What are the financing options?
We are proud to partner with Affirm to provide financing over 6, 12, or 24 months. 0% APR is available. See this page for more details next to the Affirm logo.
Do I need to purchase the Gardyn Sprout Nursery?

Specially designed to germinate yCubes, grow Microgreens, and start Baby Greens with ease, the Gardyn Sprout Nursery boosts germination speed and success so you can enjoy more harvests sooner. It’s ideal for starting new plants when you already have plant food in your Gardyn, as plant food hinders germination. The Nursery fits perfectly on your Gardyn’s lid to soak in the ambient warmth and light from your device, and lets you continually start new plants to rotate into your Gardyn as you phase out others for continuous harvests.

If you’re growing Microgreens or Baby Greens, their support plates are uniquely designed to sit in the Nursery. For members, the Microgreens germination policy only applies if you grow them following all recommendations, including using the Nursery.

Additionally, we recommend germinating yCubes and growing Microgreens/Baby Greens in separate Gardyn Sprout Nurseries.

Where can I buy plant food for the Gardyn?

You can order plant food in the app and on the website. One packet of plant food lasts approximately 3-6 months, so you may only add one packet to your cart per order.

In the app, members can order one 8-oz package of plant food with 5 of their monthly credits, or at a 50% discounted rate of $9.95. Non-members pay $19.99 per packet.

Both members and non-members pay $19.99 per packet when shopping on the website here.

How can I find out about current promotions?
Our website is always up to date with our current promotions. You can also sign up to receive email messages from us so you never miss a deal. Members get exclusive access to special sales and promotions throughout the year!
Where can I purchase accessories for my Gardyn?
Accessories are available for purchase in the Shop on the app, and here.
Can I buy a Gardyn and ship it to a friend? What about gifting a membership?

Absolutely, you can gift either or both Gardyn devices and memberships to others!

For devices, when checking out, simply enter your friend’s address as the shipping address. When your friend receives their Gardyn, they’ll be able to create an account from the Gardyn App and activate their membership to keep receiving plants.

After your purchase, you’ll receive an order confirmation email containing an Order ID. Save this number! You’ll need to share the Order ID with your friend so they can activate their pre-paid membership in the Gardyn app.

Membership

What do I get with my Gardyn membership?

We’ve designed our memberships to help you get the most out of your Gardyn experience while enjoying unique and exclusive benefits. With all that membership offers, you’ll be able to grow with confidence, no matter your experience level. To see what membership currently includes, click here! We’re always expanding our list of member perks.

When does my pre-paid membership start?

If you purchased a membership along with your device, your pre-paid membership starts on your schedule!

You can redeem your pre-paid membership in the app 24 hours after receiving your Order Confirmation email, which contains the order ID number you’ll need in the app to get started. Your membership doesn’t activate until your Gardyn connects to WiFi for the first time, so you don’t have to worry about losing any time you’ve paid for if you choose to redeem it before you’ve set up your Gardyn.

If you created your Gardyn account without redeeming your pre-paid membership and already have your Gardyn connected to WiFi, you can redeem and activate it one step using these easy steps.

What types of membership plans do you offer?

Gardyn currently offers three types of membership plans: monthly, 1-year, or 2-year. The longer the plan, the more you save! See the next question for details.

How do I purchase a membership, and how much does it cost?

You may choose to purchase a 1-year or 2-year membership either on our website when you’re purchasing a device, or directly in your Gardyn app following your device purchase. The monthly membership is only available in the app following a device purchase.

The no-commitment monthly membership costs $39 per month. The longer-term memberships provide greater savings, with 1-year members saving $5 per month ($34/month, $408/year), and 2-year members saving $10 per month ($29/month, $686/year) over the same period of time. Financing options are available.

Who, or what, is Kelby™? What does Kelby do?

Every Gardyn membership comes with Kelby™, your personal, AI Gardyning assistant. Kelby leverages your Gardyn’s advanced sensors and cameras to keep tabs on your plants 24/7, coaching you on their care from Day 1 so you can grow with confidence and enjoy the full Gardyn experience.

Kelby will send you messages and alerts that typically fall into a few main categories:

  • Just-in-time plant coaching, such as when to add plant food, how to pollinate flowers, and when and how to harvest each of your plants.
  • Device care, including water level alerts, reminders on when to do a simple clean of your water tank, and notifications if anything looks unusual.
  • Membership and special promotions, including when you’ve gained monthly credits, sales codes, plant portfolio releases and rotations, and notices about expiring memberships.
  • Inspiration! Whether it’s a new blog post, recipe ideas, or fun plant facts, Kelby has a message for every type of Gardyner!

At the end of the 30 days, your membership will auto-renew for $39 per month. If you wish to cancel your auto-renewal, you can at any time in the app.

Shipping

Do you ship outside of the United States?

Unfortunately, at this time we only ship throughout the US, including Hawaii and Alaska. We are in the early stages of logistics for international shipping. Stay tuned!

What are the shipping costs for the Gardyn and plants?

The Gardyn Home Kit ships for free in the contiguous United States as well as Hawaii and Alaska.

Members can take advantage of free shipping on one order per month (based on the anniversary date of your membership) for any credits available in your account. Free shipping does not apply to additional items ordered beyond your balance, and a shipping charge of $9.99 will apply for every 10 items ordered. You may place more than one order each month, but free shipping will only apply to one order per month in an effort to reduce carbon emissions.

Without membership, there is a flat rate shipping fee of $9.99 for yCube orders.

Can you deliver to P.O. Boxes?

The Gardyn Home device will only be sent to valid street addresses; there is no delivery to P.O. Boxes or APO/FPO addresses. We are able to ship yCube and plant orders to P.O. boxes. If the carrier cannot deliver the package and returns it to Gardyn, any additional cost for subsequent shipping attempts will be at the customer’s expense.

How can I find out about the status of my order?

Once your order has shipped and the courier has scanned the label, you will automatically receive a confirmation email with tracking information. If you would like to inquire about your Gardyn order prior to shipping, please reach out to our Customer Support team at support@mygardyn.com. If you purchase multiple items at once, remember that some items may arrive before others.

When do I receive my Gardyn once I've placed my order?

It depends on your location. Most shipments in the contiguous United States arrive in less than 5 days but can take longer for some regions and weather conditions. If you ordered multiple items, some may arrive sooner than the others.

How can I manage my Gardyn shipment?

If FedEx is the carrier, you can use FedEx Delivery Manager (FDM) to request delivery services, such as:

  • Schedule the delivery (available for residential addresses served by FedEx Express and FedEx Home Delivery)
  • Put your package on vacation hold
  • Hold your package at a FedEx location for pick up
  • Change the delivery address

If a delivery option isn’t available in FDM, this may be because of the status of the package. For example, if the shipment is already out for delivery, then the package isn’t available for a delivery appointment set up.

If you need to change your package’s delivery address, you may either do so through your FDM account, or by contacting us as support@mygardyn.com.

How big is the shipping box?

The Gardyn Home Kit 3.0 comes in one box, measuring 47in x 15in x 17in.

The Gardyn Home Kit 2.0 comes in two boxes: one for the lights (48in x 5in x 3in) and one for the remainder of the Gardyn (30in x 25in x 16in).

Can I buy a Gardyn and ship it to a friend? What about gifting a membership?

Absolutely, you can gift either or both Gardyn devices and memberships to others!

For devices, when checking out, simply enter your friend’s address as the shipping address. When your friend receives their Gardyn, they’ll be able to create an account from the Gardyn App and activate their membership to keep receiving plants.

After your purchase, you’ll receive an order confirmation email containing an Order ID. Save this number! You’ll need to share the Order ID with your friend so they can activate their pre-paid membership in the Gardyn app.

Can I return my Gardyn?

Yes. All Gardyn Home Kit Systems have a 60-day window to try out and return your Gardyn for a refund. See our Return Policy for more details.

Installation

How big is a Gardyn? Can it fit in a studio apartment?

The Gardyn was specifically designed to grow large quantities of food in a very small footprint, taking up just 2 square feet of floor space (the water tank measures 2 feet wide by 1 foot deep). When fully assembled, the Gardyn is 5 feet 4 inches tall.

If you’re in a studio apartment, make sure you’re comfortable with having the Gardyn’s lights on at full intensity (Boost mode) for 14 hours daily to ensure the healthiest and fastest plant growth. You can easily adjust the light schedule in the app to suit your household rhythms by following our guide here.

What comes with my Gardyn?

Every Gardyn Home Kit comes with the same basic components, though some parts vary in material and appearance between the Gardyn Home Kit 2.0 and 3.0. Note that the Gardyn Home Kit 2.0 ships in 2 boxes (1 for the lights, 1 with everything else), while the Gardyn 3.0 ships in 1 box.

Every Gardyn Home Kit purchase includes:

  • 2 full-spectrum LED grow lights with attached cameras
  • 3 columns
  • 1 5-gallon water tank with lid, which contains the irrigation hose system, water pump, and sensors
  • 30 yPods to hold your plants in the columns
  • 30 free yCubes so you can start growing immediately
  • 6 Pod Caps to cover any open yPods where you choose not to grow plants
  • 1 packet of plant food with a 1-teaspoon scoop
  • 1 power supply and power cord
  • User Manual to help you assemble your device, plus a Quick Start Guide with our tips for getting started

Included with Gardyn Home Kit 2.0 only:

  • 1 silicone ySleeve to easily move and handle your plants without spilling water while harvesting
Where should I set up my Gardyn?

The Gardyn is specifically designed for indoor growing and as such should never be placed outdoors. Even covered patios and screened porches experience too many temperature and humidity fluctuations to ensure healthy plants.

The Gardyn can grow anywhere in your home as long as there is a power outlet and access to your WiFi network. Ideally, the room you place your Gardyn in will have temperatures in the 65-75°F range and humidity levels in the 50-75% range. Thanks to the two full-spectrum LED grow lights, you don’t need to worry about finding a sunny spot! Some people even choose to grow their Gardyn in a closet, pantry, or basement. We recommend placing your Gardyn against a wall so you can secure the wall safety straps, and avoid looking at the lights directly, as they can be bright!

What does the Gardyn need to work?

To operate the Gardyn, you need:

  • Access to a 110V power outlet
  • An indoor space to house your Gardyn (the Gardyn is not designed or intended for outdoor use)
  • Requires a 2.4 GHz* 802.11n wireless network to connect the Gardyn to your WiFi so you can pair it with your phone. This gives you full control of your Gardyn and access to its full functionality at your fingertips.
    • The Gardyn App requires a phone, tablet, or smart device with operating systems iOS 12.0 or Android 4.1 and up. The app is free to download.
    • The Gardyn can operate without WiFi, but its functionality and your ability to control it will be limited.
    • *The Gardyn is not compatible with 5GHz
Do I need a water connection?

No. All you need is access to water clean enough to drink, and in fact, tap water is the best option! The Gardyn comes with a 5-gallon water tank which you will fill about once a week with fresh tap water. If you’re a member, Kelby will remind you when your tank’s water level is getting low.

Do I need to secure my Gardyn to the wall?

Every Gardyn comes with two wall safety straps so you can easily fasten it to the wall using the appropriate hardware for your wall type. The Gardyn is designed to balance even when full of heavy plants, but we recommend securing it to the wall as an additional safety precaution, particularly if you have young children or pets.

Gardyn Device Use & Care

What are the different parts of the Gardyn made of? Is it PVC?

We strive to build the Gardyn (and its packaging) with sustainable materials whenever possible, and we are continually testing our materials to make improvements.

Gardyn Columns, yPods, Pod Caps, & Water Tank

The Gardyn’s columns, yPods, Pod Caps, and water tank are not made of PVC but made using food-grade, FDA-compliant, ABS plastic, commonly used in medical-grade equipment and children’s toys.

Gardyn Lid Top

The Gardyn 3.0 lid top is made from Hevia wood, also known as rubberwood, a type of hardwood tree in the maple family. The Gardyn 2.0 lid top is made from bamboo wood.

yCubes: Casing, Rockwool, & Seeds

Garydyn yCubes are made up of three parts: the casing, rockwool, and seeds.

Casing

We are transitioning all of our yCubes’ casing from a corn-based plastic to a more sustainable, tapioca-based casing. Both casings are compostable in industrial composters. You’ll notice a slight visual difference between the two casings, but it will not affect your yCubes’ growth.

Rockwool

The interior of yCubes is made up of rockwool, a natural, rock-based growing medium. Rockwool holds water well and does not dry out when stored for prolonged periods of time, while also retaining its structure when wet, even after many months on your Gardyn!

Rockwool is composed of natural mineral elements melted into fibers and woven together. They are not compostable, but remember, neither are rocks!

Rockwool does not contribute harmful chemicals to the environment, and you can add rockwool from retired yCubes directly to the ground without worrying about negative environmental consequences. Reused rockwool can be especially helpful to increase water retention in gardens or flower pots that otherwise quickly go dry.

Inhaling rockwool fibers is only dangerous when you are handling and manipulating rockwool in large quantities. This danger does not apply when handling yCubes. We recommend preventing your pets from drinking water out of germination trays containing yCubes so they do not accidentally ingest any fibers. The Gardyn Sprout Nursery has a built-in cover and tray to block access to its water.

Seeds

We include 2-6 seeds in each yCube to maximize your chances of germination. The number of seeds varies depending on seed size. Gardyn’s seeds are non-GMO and organically sourced whenever possible, but don’t worry, the resulting plants you grow will still be pesticide and herbicide-free! We also offer seedless yCubes for you to grow your own varieties!

Packaging

The Gardyn Home Kit 3.0 features our sleekest packaging yet, using all-recycled materials and just 1 box to reduce the amount of materials used. All cardboard used in every Gardyn shipment also comes from 100% recycled content and 95% post-consumer waste.

What do the cameras do? Can I disable them?

Every Gardyn comes with two cameras, one on each light bar, which helps both you and Kelby monitor your Gardyn. The cameras take photos of your Gardyn every half hour to populate the Live View in your Gardyn app.

Over time, your Gardyn will produce time-lapse photos so you can watch your plants’ growth and share it with others. Members enjoy the added benefit of editing and saving these videos!

If you’re a Gardyn member, Kelby will use the images from the cameras to evaluate your Gardyn and its plants. These images help drive Kelby’s personalized recommendations and alerts to optimize your plants’ growth and device health!

The cameras are stationary and you cannot adjust their angles. You can find more details about our privacy policy here.

You can disable the cameras, and you are free to do so at any time. Just remember: no cameras means no help from Kelby!

In your Gardyn app, tap the three-line menu at the top-left of the home screen, then select “Settings”. When the cameras are on, the toggle next to “Gardyn Cameras” will appear green. If you toggle the cameras off, it will appear grey.

If any part is not working properly, what happens?

Every Gardyn comes with a one year warranty, so any damage that may happen during shipping or normal wear and tear is covered under your warranty and we will send you replacement parts at no cost to you. Simply reach out to Customer Support and send photos to support@mygardyn.com if you happen to have a broken part so we can confirm the part that needs to be replaced and record this for quality assurance. We’ll get you Gardyning again in no time!

If you’re outside of your warranty, you may purchase replacement parts here. If pricing for a particular item is not currently listed, you can contact Gardyn Support for details at support@mygardyn.com.

Are the Gardyn’s lights full spectrum?

Yes! The Gardyn has the best quality grow lighting available for hydroponic systems. The Gardyn uses full-spectrum 60W LED grow lights to mimic natural sunlight across the entire PAR range (the visible light range), without added infrared and ultraviolet rays that can be harmful.

How long do the LED lights last?

Our LED bulbs have an expected lifespan of 50,000 hours, which equates to over 5 years of continuous use. Our recommended light schedule of 16 hours/day would yield an 8.5-year lifespan.

Gardyn also warrants the components and all original parts of the Gardyn, other than yCubes, against defects in workmanship and materials for a period of 12 months from the date of original delivery.

How much energy do the lights use? What is the monthly cost?

The energy draw per second for both lights operating simultaneously is 60W on average. Following Kelby’s recommended light schedule, the Gardyn is estimated to use 60-68kWh per month depending on the device model. Gardyners have reported only paying a few dollars more per month on their usual bill due to minimal usage increases (electricity supply rates vary based on your utility provider). Some Gardyners even save on their electric bill because they end up using the Gardyn’s lights to light their home instead of other light fixtures!

Can I adjust the lighting schedule or the lights' intensity?

Yes, you can easily adjust both in the app. Choose the time of day your lights turn on and at what intensity to balance your plants’ needs with your household rhythms. Kelby recommends 14-16 hours of light on Boost mode (100% intensity) daily for the healthiest and fastest growth. Click here to learn more about adjusting your light schedule!

Can I go on vacation and leave my Gardyn?

Yes! Members can enjoy time away from their Gardyn for up to 2 weeks without worrying about a thing by turning on Vacation Mode in the app. This research-backed mode lets Kelby control your Gardyn on a unique, reduced light and water schedule to effectively press pause on your plants’ growth and conserve energy while you’re away so you won’t miss your window to pollinate or harvest! Learn more about how to prepare your Gardyn for Vacation Mode and how to enable it in the app here.

What happens if my WiFi or power goes out? Will my Gardyn still work?

Your Gardyn requires power to function, but it will keep running without WiFi on your last saved light and water schedules. Without WiFi, you’ll also have limited functionality and your Gardyn will lose connection with your app.

If your power goes out, the most important thing is to water your plants by hand if you suspect your power will not return within a day or two (how long your plants can go without automatic watering depends on their age).

Once your power and/or WiFi come back on, your Gardyn will automatically reconnect to your remembered WiFi network. For more details or to get help getting your Gardyn to turn back on or reconnect to WiFi, start here.

How often do I need to clean the Gardyn?

We recommend refreshing your tank monthly to give your plants a healthy growing environment with a consistent balance of nutrients. It’s a simple process that only takes about 10 minutes.

With regular HydroBoost use right from the start, you can also decrease the need for (and potentially eliminate) whole-device cleanings later in your Gardyn’s life by keeping the inside of your Gardyn clean (while boosting plant health, among other benefits!).

Can I use tap water in the Gardyn?

Yes! Tap water is in fact the best water source to use in your Gardyn. The only type of water we don’t recommend using in your Gardyn is softened water treated with a water softener. Please note, this is different from naturally soft water. Click here to learn more.

How much water does the tank reservoir hold?

The Gardyn’s water tank holds up to 5 gallons of water. After you’ve added plant food for the first time, we recommend topping off weekly with water and dissolved plant food to maintain a consistent balance of nutrients for healthy, happy plants.

Do I need to measure my water’s pH levels?

No! We designed the Gardyn system to be as simple as possible. Our plant food plus our plant-based water treatment solution, HydroBoost, are specially formulated so you don’t have to worry about pH.

Simply follow our plant food usage guidelines, top off your tank weekly along with HydroBoost, and refresh it monthly for a clean and healthy Gardyn, inside and out.

Plants & Growing Tips

What kind of plants can I grow on my Gardyn?

All plants available in the Gardyn portfolio have gone through a rigorous testing and validation process to ensure Gardyners will have a positive growing experience. We only bring you the most delicious, nutritious, and beautiful harvests, and we’re always adding new varieties to the portfolio!

If you’re interested in growing a variety outside of our portfolio, try our seedless yCubes, available in the app’s yCube Shop! Designed for the experimental Gardyner, you can pop in your own seeds and watch them grow. For tips on picking your own varieties, click here!

Where is the full list of plants that you offer?

You can find the full list of our plant varieties, including greens, herbs, fruits, vegetables, and flowers, on our website and in the Plant Book in your Gardyn app. We are constantly adding new varieties and routinely update the list as new plants become available.

Will you be adding more plants?

Yes! We are always expanding our plant portfolio, and members get access to the widest variety and most unique plants we offer.

What type of seeds are you using?

All of Gardyn’s seeds are non-GMO and organically sourced whenever possible, but don’t worry, the resulting plants you grow will still be pesticide and herbicide-free! We also offer seedless yCubes for you to grow your own varieties. All plants available in the Gardyn portfolio have gone through a rigorous testing and validation process to ensure Gardyners will have a positive growing experience. We are constantly adding new varieties to try!

How and where do I order plants?

You can order plants directly through your Gardyn app. From the 3-line menu in the top left of your app’s home screen, select the Shop to explore all of our plants, including Microgreens and Baby Greens.

If you’re a member, you can use your monthly credit balance to order plants for free! Orders in excess of members’ credit balance will be charged at a discounted rate of $1.99 per yCube plus flat-rate shipping (versus $4.99 per yCube plus a flat rate shipping fee of $9.99 for non-members).

Members can take advantage of free shipping on one order per month (based on the anniversary date of your membership) for any credits available in your account. Free shipping does not apply to additional items ordered beyond your balance, and a shipping charge of $9.99 will apply for every 10 items ordered. You may place more than one order each month, but free shipping will only apply to one order per month in an effort to reduce carbon emissions. Without membership, there is a flat rate shipping fee of $9.99 for yCube orders.

How quickly do plants grow on Gardyn?

Plant growth and germination times depend on the species of the plant. Lettuces, for example, can sprout in a matter of days, and will typically reach full size in about 3-4 weeks. Cherry Tomatoes, on the other hand, can take 60 days to start forming flowers and begin bearing fruit. You can learn more about growth rates and germination speed for each species we offer in the Plant Book, found in your Gardyn app.

The environment around and inside your Gardyn also factors into how fast your plants grow. Externally, ensure the room your Gardyn is in maintains temperature and humidity levels in our recommended ranges. Internally, keeping your Gardyn columns and water tank clean with regular tank refreshes and weekly HydroBoost additions is the best, lowest-maintenance way to ensure healthy plant roots.

Do I need to wash the plants before eating them?

The beauty of Gardyn-grown produce is that you know your plants’ origin. Since your Gardyn plants are all pesticide- and herbicide-free and grown in your home, you can feel comfortable snacking on plants directly from the Gardyn without washing them first! Bonus: there’s no grit or soil or wash off!

What growing medium do you use?

Our growing medium of choice that makes up the interior of yCubes is rockwool, a natural, rock-based material. Rockwool holds water well and does not dry out when stored for prolonged periods of time, while also retaining its structure when wet, even after many months on your Gardyn!

Rockwool is composed of natural mineral elements melted into fibers and woven together. They are not compostable, but remember, neither are rocks!

Rockwool does not contribute harmful chemicals to the environment, and you can add rockwool from retired yCubes directly to the ground without worrying about negative environmental consequences. Reused rockwool can be especially helpful to increase water retention in gardens or flower pots that otherwise quickly go dry.

Inhaling rockwool fibers is only dangerous when you are handling and manipulating rockwool in large quantities. This danger does not apply when handling yCubes. We recommend preventing your pets from drinking water out of germination trays containing yCubes so they do not accidentally ingest any fibers. The Gardyn Sprout Nursery has a built-in cover and tray to block access to its water.

How often do I need to add water?

In the first 30 days when your plants are young, they won’t drink much water. When you have mature plants, and especially fruiting plants, which drink a lot, you’ll need to add water with dissolved plant food at least once per week. We call these weekly additions "topping off your tank."

Kelby will remind members if their water tank starts to run low, but it’s best to keep your tank at least 50% full at all times. This gives your plants the most balanced nutrients for healthy growth, and it ensures your tank never runs too low for the pump to reach.

What is the plant food you provide made of?

Gardyn plant food is mineral-based to give plants access to the nutrients they need in a way that helps keep your device clean. The ingredients listed are also found in natural soil, including:

  • Nitrogen: 8% (includes 1% Ammoniacal Nitrogen and 7% Nitrate Nitrogen)
  • Available Phosphate: 5%
  • Soluble Potash: 13%
  • Calcium: 7%
  • Magnesium: 2.5%
  • Water Soluble Magnesium: 2.5%
  • Sulfur: 4.5%
  • Iron: 0.2%
  • Manganese: 0.03%
  • Molybdenum as 0.001%
Can I use organic plant food?

We do not recommend using organic plant food in your Gardyn (or in any hydroponic system). Mineral plant food provides the same nutrients as organic plant food, but without generating excess waste that will clog your pump. Since there is no soil present in a hydroponic setup, mineral plant food is always preferred because it is cleaner and will prevent biofilm from developing in your tank and columns. Your plants will still be organic, so no worries! You can learn more about what our plant food is made of here.

What do I do with a plant once I'm done with it?

Option 1: Compost it

Simply remove the plant and rockwool from the yCube’s casing, and add them to your home compost pile. The yCubes’ corn- or tapioca-based casing can be composted in industrial composters – check with your town or local waste management system to see if this is an option near you.

Option 2: Transplant it outside

Many Gardyners like to start plants in their Gardyn before transplanting them outdoors, especially in the warmer months. This is also an excellent redirection when dealing with pests, so you can give your plants another chance in nature, which often remedies indoor pest problems naturally.

Why do I need to replace plants from time to time?

As your plants grow and mature, you’ll enjoy harvesting them many times. All plants, however, come to a natural end to their life cycle. The specific timing greatly depends on the plant variety. All lettuces and herbs, for example, eventually bolt, which is when the plant starts growing flowers and going to seed instead of growing more leaves.

To help enjoy continuous harvests for all of your plants, we recommend germinating new yCubes in the Gardyn Sprout Nursery while you’re harvesting their mature counterparts so that as one plant reaches the end of its life cycle, you have another ready to take its place.

Can I grow my own seeds?

Yes! If you’re looking to experiment, we recommend choosing plants that are determinate (meaning they stop growing in size at a set point) and, if you’re looking at fruiting plants, ones with smaller fruit. We offer seedless yCubes so you can experiment with ease.

Are there any plants that are toxic to pets?

Some Gardyn plants should not be eaten by pets, including but not limited to Cherry Tomato and Pepper leaves. If you have a curious pet and are concerned about them snacking on your Gardyn, we recommend reviewing the ASPCA Toxic and Non-toxic Plants List, and placing any plants with potential negative effects at the top of your Gardyn. You can also purchase a pet or baby gate to block off your Gardyn from unwanted attention.

We recommend preventing your pets from drinking water out of germination trays containing yCubes so they do not ingest any fibers from the rockwool (keeping the lid on your Gardyn Nursery helps with this).

Does Gardyn replace plants that don't sprout or grow?

Yes! This is a member-only benefit and includes yCubes, Strawberries, and Microgreen seed pads. For details on this policy, click here.

Can I grow marijuana in the Gardyn?

The Gardyn boasts the highest quality, full-spectrum LED grow lights available in a commercial hydroponic system, and as such are well equipped to grow cannabis. Gardyners have reported using the Gardyn to grow cannabis with excellent results. Growing cannabis isn’t legal everywhere, so check your local and state laws first. Gardyn does not condone growing cannabis in states where it is not legal.

Is it possible to get pests?

Pest issues are less common in indoor gardening, but they can happen from time to time. Gardyn sends plant yCubes that are composed of inorganic material and seeds to eliminate the possibility of outside contamination.

However, pests can still find their way inside through outside doors or windows, or from being carried in on soil-based houseplants or pets. We offer many resources and expert plant support should you ever run into any pest issues. Plus, members can rest easy knowing they’ve always got enough credits banked should they need to replace any plants.

Gardyn App

Is the Gardyn App free? Do I have to download it?

The Gardyn app is free to download.

While you don’t have to download the app, it is the only way you can connect Kelby, your smart Gardyning assistant, with your device. The app also lets you control your device, from activating Kelby Assist so Kelby can adjust your light and water schedules based on your plants’ growth, to switching into Vacation Mode, logging your tank refreshes, checking on your plants through Live View, and more. Plus, the app is the easiest way to shop for new plants and find answers to your questions in the Help Center.

What type of phone do I need for the Gardyn App?

The Gardyn App requires a phone, tablet, or smart device with operating systems iOS 12.0 or Android 5.0 and up.

What can I see or control from the Gardyn App?

The Gardyn App makes it possible for you to control your Gardyn’s automatic lighting and water scheduling remotely. If you are a Gardyn member, you will also receive notifications from Kelby, the Gardyn Smart Assistant. You can view photos of your plants growing, as well as your Gardyn’s current temperature, humidity, water level, watering schedule and light intensity.

What kind of notifications will I receive on my phone?

Kelby sends you messages through your app and to the email address linked with your Gardyn account. App messages arrive just like text messages from a friend, filled with helpful tips, alerts, and personalized guidance. You can choose if you’d like Kelby to send messages to either or both your phone and email by adjusting your settings in the app.

Kelby sends you messages and alerts that typically fall into a few main categories:

  • Just-in-time plant coaching, such as when to add plant food, how to pollinate flowers, and when and how to harvest each of your plants.
  • Device care, including water level alerts, reminders on when to do a simple clean of your water tank, and notifications if anything looks unusual.
  • Membership and special promotions, including when you’ve gained monthly credits, sales codes, plant portfolio releases and rotations, and notices about membership renewals.
  • Inspiration! Whether it’s a new blog post, recipe ideas, or fun plant facts, Kelby has a message for every type of Gardyner!
