The best digital timer for grow lights for most indoor gardens is the BN-LINK Indoor 7-Day Programmable Digital Timer Outlet. It combines 8 on/off programs, 2 grounded outlets and settings as short as 1 minute, giving you more control than a basic daily timer.

A daily timer works well when your grow light follows the same schedule every day. A 7-day model makes more sense when seedlings, herbs or houseplants need different routines across the week.

For a simpler overview of timer features, compare this roundup with our guide to the Best Grow Light Timer. If your light already has its own schedule, see our picks for the best grow light no timer.

How we chose the best digital timer for grow lights

The best digital timer for grow lights should match your schedule, outlet needs and installation location. We compared the listed programming options, outlet designs, backup memory, ratings and stated indoor or outdoor use.

Our score weighs specs, features and buyer feedback against what you're shopping for. A higher score here means the timer offers a stronger mix of schedule control and grow-light practicality.

Weekly scheduling received the most weight because it reduces repeated setup. Outlet control also matters: some models run two outlets together, while VIVOSUN provides independent outlets.

To adjust a compatible fixture's brightness, compare LED grow light dimmers.

We also looked at daily simplicity. A timer with 1 daily program may be easier to set than a model with 20 program groups, even when it has fewer options.

The best digital timer for grow lights by use

The BN-LINK 7-day model is the strongest all-around pick, while the other timers solve specific needs such as simple daily schedules, cycle control or weather-resistant placement.

1

BN-LINK Indoor 7-Day Programmable Digital Timer Outlet: Best for flexible weekly schedules

9.7/10Our score

• Up to 8 on/off programs
• 2 grounded outlets controlled together
• 1-minute settings
• Random and daylight saving modes

This BN-LINK timer gives indoor growers the most control over weekly lighting routines in this group. Its 2 outlets are controlled simultaneously.

See it on Amazon

Pros

• 8 on/off programs
• 1-minute settings
• Backup battery

Cons

• No LCD backlight
• Both outlets run together

BN-LINK is the best choice when you want to build a weekly grow-light routine with several changes. It supports up to 8 on/off programs, and each setting can be as short as 1 minute.

The 2 grounded outlets are controlled simultaneously. That suits two lights that should turn on and off together, but it won't give each outlet its own schedule.

A backup battery keeps the settings during a power outage, and the timer includes daylight saving and random vacation modes. The random mode has more value for home lighting than for plant growth, so use it only when that function fits your setup.

The timer is rated at 120V, 60 Hz and 15A/1725W. BN-LINK also describes support for 3W or higher LEDs, though lower-wattage LED strips should be checked before regular use.

Choose this model when weekly control matters most. Its main drawback is the lack of an LCD backlight, so place it where the display can be read in normal room light.

2

BN-LINK Indoor 24H Programmable Digital Timer Outlet: Best for simple daily routines

9.6/10Our score

• 2 daily timer programs
• 2-pack
• Slim side-outlet design
• Backup memory for over 3 months

The BN-LINK 24-hour timer suits growers who repeat the same light schedule every day. The 2-pack can serve two separate grow-light setups.

See it on Amazon

Pros

• Compact side outlet
• Two daily programs
• Quiet operation

Cons

• Only 2 daily programs
• 2-prong non-grounded outlet

This BN-LINK 2-pack suits two grow-light areas that each need a repeat daily schedule. Each timer has 2 daily programs, so you can set a morning start and an evening shutoff without managing a full weekly calendar.

The slim side-outlet design helps keep the neighboring wall socket available. The 2-prong non-grounded outlet is intended for compatible indoor devices, and the stated rating is 125V/15A/1875W.

Its built-in backup battery preserves settings for over 3 months after a power interruption or when unplugged. That is useful if you move a timer between grow spaces or experience occasional power loss.

Pick this set for straightforward routines and separate light locations. Choose a 7-day model instead if your plants need different schedules on different days.

3

Fosmon 24 Hour Programmable Digital Timer Outlet: Best for a compact 2-pack

9.5/10Our score

• 24-hour on/off program
• 2-pack
• Large LCD numbers
• Backup battery for more than 100 hours

Fosmon offers two compact timers for growers who want separate control of two indoor lights. Its large LCD and manual mode keep daily operation straightforward.

See it on Amazon

Pros

• Two timers in one pack
• Large LCD
• Side-entry plug design

Cons

• Backup memory is shorter than several picks
• One program setting

Fosmon is a practical compact choice when you want two separate timers in one pack. Each timer has one polarized outlet and a 24-hour on/off program for a repeated daily lighting cycle.

The large LCD numbers make the schedule easier to check, while the side-entry plug can fit behind furniture or in a tight area. Its backup battery keeps settings for more than 100 hours when external power is unavailable.

Fosmon rates the timer at 125V/15A and describes compatibility with incandescent, CFL and LED lights. Use the stated rating as a limit, and match it with the needs of your grow light.

This pick works best for two small indoor setups with similar daily patterns. It is less suitable when you need weekly day selection or several separate on/off events.

4

DEWENWILS 24 Hour Digital Light Timer: Best for easy-to-read daily control

9.3/10Our score

• 1 daily repeat setting
• Large 2-inch display
• Backup memory for 3 months
• Silent operation

The DEWENWILS daily timer is a good fit when one repeat schedule is enough and a large display matters. It also keeps settings during a power interruption for up to 3 months.

See it on Amazon

Pros

• Large display
• Silent operation
• 3-month backup memory

Cons

• Only 1 daily setting
• Lower stated wattage than some picks

DEWENWILS keeps daily control simple with 1 daily repeat setting and a large 2-inch display. That makes it a good fit for a single grow light that follows the same on and off times each day.

The timer has 1 polarized outlet and a 125V, 60Hz, 15A/1000W rating. Its backup battery keeps programmed settings for 3 months if power goes out or the timer is disconnected.

The silent operation suits a bedroom, office or other indoor growing area where clicking sounds would be distracting. The large display also helps when you need to confirm the current schedule quickly.

Choose it when ease of reading matters more than multiple programs. Its lower stated wattage and single daily setting make it less flexible than the leading 7-day picks.

5

DEWENWILS Indoor 24 Hour Programmable Digital Timer: Best for 3 daily programs

9.1/10Our score

• 3 daily repeat programs
• 2-pack
• 3-prong design
• Backup memory for up to 3 months

This DEWENWILS model adds more daily schedule control than a basic one-program timer. The 2-pack works well when separate indoor lights need matching or different routines.

See it on Amazon

Pros

• 3 daily programs
• 2-pack
• Compact design

Cons

• Daily schedule only
• No weekly day selection

This DEWENWILS model is a middle ground between a basic daily timer and a full weekly controller. It provides 3 daily repeat programs, allowing more than one lighting event in a 24-hour routine.

The 2-pack gives you two timers for separate indoor lights. Each timer has a 3-prong outlet and a stated rating of 125V, 60Hz, 15A/1000W.

Its compact design is made to avoid blocking other sockets, and the backup memory preserves settings for up to 3 months. Silent operation is useful around sleeping areas and workspaces.

Select this model if you need several daily events but not different schedules by day of the week. For a full weekly plan, move up to BN-LINK, HBN or VIVOSUN.

6

Techbee Digital Infinite Repeat Cycle Intermittent Timer: Best for cycle and countdown schedules

8.8/10Our score

• Daily timer
• Countdown
• Turn-on and turn-off timer
• Short on/off cycle timer

Techbee is the specialist pick for growers who need more than a standard sunrise and sunset routine. Its cycle and countdown functions suit experiments with intermittent lighting.

See it on Amazon

Pros

• Cycle timer
• Countdown function
• Large screen

Cons

• More setup choices to learn
• Only 1 timer in the pack

Techbee is the most specialized timer in this roundup because it supports daily timing, countdowns and short repeating on/off cycles. That cycle function can help when your lighting plan uses intervals instead of one continuous daily period.

The timer is rated at 120V and 15A and has a large screen for viewing the settings. Its built-in battery memorizes programs during power outages, and the plastic housing includes a child lock function.

Use the countdown mode when a light needs to run for a limited period. Use the cycle mode only when that type of intermittent schedule matches your plants and light instructions.

Techbee is a better fit for an advanced routine than a first timer purchase. If you only need one daily on and off period, a simpler model will take less setup.

7

myTouchSmart 26898-P1 Indoor/Outdoor Weather Resistant Digital Plug-in: Best for weather-resistant placement

8.6/10Our score

• 2 grounded outlets
• Custom on/off settings
• Daily presets
• Up to 24-hour countdown

myTouchSmart stands out when a timer may serve indoor or weather-resistant outdoor lighting. Its presets and custom controls cover more than one fixed daily routine.

See it on Amazon

Pros

• Weather-resistant design
• 2 grounded outlets
• Mounting bracket

Cons

• Not a 7-day timer
• Larger than compact indoor picks

myTouchSmart is the standout choice when a timer may be used indoors or outdoors in a weather-resistant location. It has 2 grounded outlets, custom on/off settings, daily presets and a countdown of up to 24 hours.

The timer works with CFL, LED, incandescent and halogen light sources. A large LCD and blue LED indicators show active programs, while the attached bracket supports mounting near an outlet.

Its rating is 125V/60Hz and 15A/1875W for general purpose and resistive loads. For outdoor use, place it in a location that matches the timer's weather-resistant design and keep the grow-light connection suitable for that environment.

Choose this model when weather resistance and flexible presets matter more than 7-day scheduling. It is larger and less focused on indoor plant routines than the compact picks.

8

HBN Outlet Timer Indoor Plug in Timers: Best for 8 programs on a budget

8.3/10Our score

• Up to 8 on/off programs
• 7-day scheduling
• Random vacation mode
• Dual grounded outlets

HBN provides many of the scheduling controls needed for a weekly grow-light routine. It is a practical alternative when you want dual outlets and random mode.

See it on Amazon

Pros

• 8 programs
• 7-day schedule
• Dual grounded outlets

Cons

• Indoor timer
• Both outlets are controlled together

HBN gives you a 7-day schedule with up to 8 on/off programs, making it a useful alternative to the top BN-LINK pick. The 2 grounded outlets are controlled together, so both connected lights follow the same programmed events.

Settings can be as short as 1 minute, and the timer supports individual days or preset combinations. Daylight saving and random vacation modes add flexibility for home lighting, although random timing is not a plant-growth feature.

The stated rating is 125V, 60Hz, 15A/1875W resistive, 10A/1250W tungsten and 1/2 HP. Use those limits to compare your equipment before connecting it.

Pick HBN when you want weekly scheduling and dual grounded outlets. BN-LINK scores higher here because its product data gives clearer detail about backup memory and setup controls.

9

VIVOSUN Digital Timer Outlet 7 Day Programmable: Best for the most program groups

8.1/10Our score

• 20 on/off program groups
• 2 independent outlets
• 1-minute interval
• Countdown and random modes

VIVOSUN gives advanced indoor growers the largest number of program groups here. Its independent outlets can control two devices on separate schedules.

See it on Amazon

Pros

• 20 program groups
• Independent outlets
• Countdown setting

Cons

• More programming work
• Lower score for simpler grow-light routines

VIVOSUN is the choice for the most complex schedule in this group. It offers 20 on/off program groups, a countdown setting and 2 independent outlets, so two connected devices can follow different schedules.

The timer supports 1-minute intervals and schedules from 1 day to 7 days. Its 3-prong design is rated at 125V, 60Hz and 15A, with a maximum load of 1875W.

A larger LCD, side-entry design, rechargeable battery and child lock add practical controls. The random mode is intended to vary light timing for an occupied-home effect, not to replace a plant-specific lighting schedule.

Choose VIVOSUN if you truly need many events or separate outlet control. For one grow light with one daily routine, its larger programming range may add work without adding value.

How many programs does your grow-light timer need?

Most single-light setups need only one on time and one off time each day. A 24-hour timer with 1 or 2 daily programs is enough when the schedule stays the same every day.

Choose 3 or more daily programs when your plan includes several lighting periods. Techbee adds countdown and cycle functions for routines that do not fit a simple morning-to-evening pattern.

A 7-day timer becomes useful when the schedule changes by day. BN-LINK and HBN offer up to 8 programs, while VIVOSUN goes up to 20 program groups.

More programs are not automatically better. Extra settings can make setup harder, so choose the smallest programming range that covers your actual light schedule.

Should you choose one outlet or two?

Choose one outlet when one grow light runs by itself. A single outlet keeps the setup simple and avoids connecting a second device that does not need the same schedule.

Two outlets help when two lights should turn on and off together. BN-LINK, HBN and myTouchSmart use dual outlets, but their outlets are not described as independently scheduled.

VIVOSUN is different because its 2 outlets are independent. That makes it the best fit here for two devices with different routines.

Check whether the timer is grounded or non-grounded before connecting equipment. The BN-LINK 24-hour model has a 2-prong non-grounded outlet, while several other picks use 3-prong designs.

How to set up a digital timer for grow lights

Set the current day and time first, then program the light's on and off events. After saving the schedule, switch the timer to AUTO so it follows the programmed times.

Keep the light schedule consistent unless your plant plan calls for a change. Put the timer where you can read the display and reach the controls without pulling on the grow-light cord.

Check the timer's voltage, current and wattage limits before connecting the light. A timer's maximum rating does not mean every attached device should be used at that limit.

After a power outage, confirm the clock, program and AUTO mode. Battery backup can preserve settings, but checking the display helps catch a clock reset before it affects the next light cycle.

If you are choosing the light and timer together, compare our Best Grow Light With Timer guide. A stand-mounted setup may also benefit from the Best Grow Light On A Stand roundup.

Best digital timer for grow lights: final picks

The best digital timer for grow lights is BN-LINK's 7-day model if you want flexible weekly schedules, 8 programs and two grounded outlets controlled together. Pick the BN-LINK 24-hour 2-pack for two simple daily routines.

Choose VIVOSUN when independent outlets and 20 program groups matter. Choose Techbee for countdown or repeating cycles, myTouchSmart for weather-resistant placement, and DEWENWILS when a compact daily schedule is enough.

For a complete combined growing setup, see the Best Hydroponic System With Grow Light And Timer. The right timer is the one that matches your light schedule without adding controls you will not use.

Frequently asked questions

What is the best digital timer for grow lights?

The BN-LINK Indoor 7-Day Programmable Digital Timer Outlet is the best digital timer for grow lights for most indoor gardens. It has 8 on/off programs, 2 grounded outlets controlled together, 1-minute settings and a backup battery that keeps settings during a power interruption.

Choose VIVOSUN if you need independent outlets and up to 20 program groups.

How long should grow lights stay on a timer?

The right schedule depends on the plant and grow light, but a consistent daily routine is the main goal. Set the timer to provide the light period your plants need, then keep the on and off times steady.

Our guide on How Long Should You Leave Grow Lights On? explains how to plan the daily cycle.

Are digital timers good for LED grow lights?

Digital timers can work with compatible LED grow lights, but check the timer's outlet type and electrical rating before connecting equipment. Some low-wattage LED products may need testing before regular use.

Keep the timer indoors unless it is specifically weather resistant, such as the myTouchSmart model.

Do grow-light timers keep their settings after a power outage?

Several timers in this roundup include backup memory. BN-LINK, DEWENWILS and VIVOSUN describe battery-backed settings, while Fosmon specifies more than 100 hours.

After an outage, check the clock and confirm that the timer is in AUTO mode before relying on the next lighting cycle.
