Gardyn grow light schedules: nights, dimming and living with the light
Gardyn recommends 14 to 16 continuous hours of Boost (full-brightness) light every day, followed by a dark period, and you can slide that block earlier or later in the app to fit your sleep. Run the lights at night only if your Gardyn sits somewhere that stays dark in daylight, like a windowless basement. Most schedule surprises, such as a dim setting that snaps back to Boost, come from a few app behaviors that are easy to work with.
Key takeaways
- Aim for 14 to 16 Boost hours a day. At 17 or more, Gardyn notes plants can turn bitter, develop pale spots or bolt early.
- Dimmed light does not count toward Boost hours, so add Dim around the edges of your schedule.
- Overnight shifts must be split at midnight, and Gardyn recommends night lighting only for spaces that are dark during the day.
- A tap on the light tile or the silver lid button is temporary; it lasts only until the next scheduled light shift.
- Gardyn finds the lights rarely cause crispy or brown leaf edges. Late top-offs, plant food measuring and low humidity are the usual causes.
How many hours of light does a Gardyn need?
Gardyn recommends 14 to 16 hours of Boost light a day, in one continuous block, which mimics a full summer day. Boost means the lights are at 100% intensity, the only setting that counts toward your daily total. Gardyn recommends this schedule however much natural light your home gets, and the help center explains why sunny days don’t replace the lights.
In the app, each schedule gets a rating of Low, Ok, Great, Intense or Too High (how the rating works); aim for Great. This table shows what Gardyn says to look for at different amounts of Boost light.
| Boost hours per day | What to look for | What to do |
|---|---|---|
| Under 14 | Plants can grow leggy, turn pale or bolt early | Add Boost hours until the app rates the schedule Great |
| 14 to 16 | Gardyn’s recommended range for the fastest growth | Keep it, and shift the block to suit your day |
| 17 or more | Bitter flavors, premature bolting, pale spots and weaker plants | Trim Boost hours back to 16 or fewer |
Can plants thrive on 10 to 12 hours of light?
A 10 to 12 hour schedule sits below Gardyn’s recommended 14 to 16 Boost hours, so the app will suggest adding Boost hours. Watch for bolting, when a plant grows tall and elongated, forms flower buds and its leaves turn tougher and more bitter.
Is there a gentler schedule for lettuce and herbs?
Gardyn recommends the same 14 to 16 Boost hours for every plant and handles the difference with placement. Every Gardyn has high, medium and low light zones: the center is the high light zone, medium light surrounds it, and the outer and lower slots get the least. Each plant’s Plant Book page lists its zone, so check the pages for romaine or basil before you place them. Fruiting plants belong in the center.
Does your Gardyn need a dark period at night?
Yes. Gardyn says plants need periods of darkness, just like nighttime in nature, so keep a dark block in every daily schedule. The help center compares it to sleep, and notes that a Gardyn in a room with daylight that also gets LED light at night can leave plants over-lit.
Can you run Gardyn lights at night?
Only if your Gardyn is in a space that stays dark during daylight hours, such as a basement with no windows. In a room with daylight, Gardyn recommends a daytime schedule so plants rest when you do (Gardyn’s guidance on night lighting).
How do you set lights to turn off after midnight?
The schedule resets at midnight, so a shift that crosses it must be saved as two: one ending at 11:59 PM and one starting at 12:00 AM. The lighting and watering guide shows where each setting lives.
What if your house runs around 80°F?
Keep the daytime schedule and use placement. Gardyn’s Placement Guide gives each plant its best mix of light and temperature, and Gardyn notes leafy greens and herbs prefer cooler spots while most fruiting crops prefer warmer ones. Gardyn lists hot weather as one of the most common causes of bolting, so watch greens and herbs for it.
How do you shift the light schedule to fit your sleep?
Move the whole 14 to 16 hour block in the app so it starts after you wake and ends before you sleep. These sample schedules all land in the recommended range.
| Your routine | Sample Boost block | Boost hours |
|---|---|---|
| Early riser, early bed | 6 AM to 8 PM | 14 |
| Lights should not be on at dawn | 8 AM to 11 PM | 15 |
| Night owl | 9 AM to midnight (save the end as 11:59 PM) | 15 |
| Late shift worker | 11 AM to 2 AM (split at midnight) | 15 |
If the Gardyn shares a room with a sleeping baby or a light sleeper, end the Boost block before their bedtime or place it in another room. Gardyn Studio 2 also adds a Sunrise/Sunset lighting mode that mimics nature.
Can you shift your light cycle around peak electricity rates?
Yes, as long as the block stays in the daytime and keeps its full 14 to 16 Boost hours. In the energy figures Gardyn publishes on its comparison charts, Gardyn Home 4 uses 47 kWh a month. To plan around your utility’s rates:
- Slide the Boost block in the app to the daytime hours that suit you.
- Keep the block continuous; Gardyn advises against swapping Boost hours for dimmed light.
- Run lights overnight only if the Gardyn sits somewhere dark during the day.
How do you live with bright grow lights in an open living space?
Give it about a week. The help center notes a Gardyn is bright at first and the light softens considerably as plants grow, and many owners find the brightness less noticeable within a week or so. In the meantime:
- Add a Dim shift for an hour at either end of the day, on top of your Boost hours.
- Give the round silver button near the front left of the lid a short press to switch the lights off until their next scheduled time. Do not hold it down, which puts the Gardyn into pairing mode.
Should you cover your Gardyn to dim the lights?
The ways Gardyn supports for softening the light are the Dim setting, a schedule shift or a short press of the silver button. Kelby’s cameras are built into the light bars, and Gardyn asks owners to keep them on, clean and unobstructed for the best guidance.
Why does your dim setting keep going back to Boost?
A change you make from the light tile in Schedule Mode is temporary, so the lights return to the schedule at the start of the next light shift. That is also why lights you switched off can come back on. To make a dim level stick, edit the shift itself. Changing the dim percentage while dimmed applies the new level to every dimmed shift.
Why are your lights on, off or an hour off schedule?
Most mismatches trace back to a temporary change, the time zone setting or a lost Wi-Fi connection. This table matches what you see to the likely reason.
| What you see | Likely reason | What to do |
|---|---|---|
| Lights come back on after you turned them off | Temporary change ended at the next light shift | Edit the schedule instead of using the tile or button |
| Lights an hour ahead or behind | Time zone setting is the first thing to check | Confirm it under the gear icon, then Advanced |
| Overnight lights don’t follow the times you set | Shift crosses midnight without being split | Save it as two shifts, one ending at 11:59 PM and one starting at 12:00 AM |
| Schedule shows no block for night hours | Off hours never appear as a time slot | Nothing; this is normal |
| Light tile missing and a red offline banner | Gardyn is offline | Tap Reconnect on the Home screen |
| Lights stay on past schedule or won’t turn off | Lights not matching the app’s settings | Use the troubleshooting guide below |
If the Wi-Fi drops, your Gardyn keeps running the last schedule it saved, but you can’t change it until it reconnects. The lighting schedule troubleshooting guide walks through the fixes in order. If the lights still don’t follow your schedule after working through it, contact Gardyn support at support@mygardyn.com.
How do you restore the default light schedule?
Hand the lights back to Kelby. If you switched to Manual Mode, the light tile’s Review Mode option returns you to Schedule Mode so Kelby can manage the lights again.
Can Kelby manage your light schedule?
Yes. Kelby manages your Gardyn’s light and water from day one and flags when plants need more or less light. Repeated suggestions usually mean your schedule rating is above or below Great, and the app suggests how many Boost hours to add or subtract. Kelby’s monitoring, alerts and tasks come with a Gardyn membership, but you can set light schedules in the free app without one. For a question about your own plants, use Ask Kelby in the app.
Should the lights stay on while seeds germinate?
Yes. When you germinate on your Gardyn, the help center recommends letting Kelby manage watering and keeping 14 to 16 Boost hours a day, the same schedule as mature plants. The hydroponic seed starting guide covers the rest of germination, and the Gardyn Sprout Nursery starts new yCubes on your Gardyn’s lid while the tower keeps producing.
Can grow lights burn your plants?
Rarely. Gardyn notes the lights rarely dry plants out. Brown, crispy edges are most common on lettuces and leafy greens such as romaine and arugula, and they usually come from late tank top-offs or refreshes, plant food that wasn’t measured and dissolved correctly, or low room humidity. The signs Gardyn ties to too much light are different: pale spots, bitter leaves and early bolting at 17 or more Boost hours. Trim or move any plant growing too close to the light bars or cameras, and see Gardyn’s guide to crispy and brown leaves for each cause. If you see something it doesn’t cover, ask Kelby or contact Gardyn support.

Frequently asked questions
Can you run Gardyn lights without the app or a membership?
Yes. A membership is not required to set light and water schedules in the free Gardyn app. Once a schedule is saved, the Gardyn keeps following it even if Wi-Fi drops, though you can’t change it until the unit reconnects. A short press of the silver button on the lid also switches the lights on or off until the next scheduled shift, no phone needed.
Do the lights need to be on when your Gardyn waters?
No. Lighting and watering run on separate schedules in the app, each with its own tile on the Home screen. By default, watering runs 3 times a day for about 5 minutes, and with Smart Watering, Kelby times those cycles around your plants’ life stage, so you don’t need to line them up with your light shifts.
Can a gift recipient change the light schedule or dim the lights?
Yes. The person who sets up the Gardyn creates their own app account, pairs the unit and then controls every setting, including the light schedule, dimming and the Sunrise/Sunset mode on Gardyn Studio 2. If a prepaid membership came with the gift, the recipient activates it in the app using the Order ID the giver shares.
Does dimmed light count toward the 14 to 16 hours?
No. The recommended hours are Boost hours at full intensity, and Gardyn advises against swapping Boost hours for dimmed light. Dim is useful for an extra hour at either end of your day when you want the room softer, as long as the full Boost block stays in place before or after it.
Will a one-hour schedule shift after a time change hurt your plants?
A schedule that runs an hour early or late still gives your plants the same number of Boost hours, which is what Gardyn’s schedule rating measures. The bigger issue is usually matching the lights to your day again. Check the time zone setting in the app first, then the lighting schedule troubleshooting guide if the lights still don’t follow the times you saved.
How long do Gardyn LEDs last on a daily schedule?
Gardyn’s LEDs are rated for 50,000 hours, which Gardyn puts at about 8.5 years at 16 hours a day, the top of the recommended range. Because that figure already assumes a full schedule, you can keep your plants on 14 to 16 Boost hours without trimming light to save the LEDs.
