Rated quite highly, this grow light timer has a big fan base among those with an indoor garden.


The BN-LINK digital timer is a UL-listed one since it went through strict quality and safety control.

This is probably the first good thing about this timer.

With this one, you can make your own schedule, or you can use some of the pre-programmed combinations.

Also, there’s a Daylight Savings mode that you can switch to when the daylight savings time comes.

As the BN-LINK 7 runs on batteries and pretty strong ones for that matter, so even if there was a power outage, this is one of the digital timers that will be up for the challenge in such situations.

The BN-LINK 7 can control up to two grounded outlets, so with it, you could have your indoor garden set up with 8 on/off programs.

These programs could be as short as one minute if that’s what you need, and they are controlled simultaneously.

What we like
  • Can work in Manual Operation mode when there is no power supply
  • Simultaneously controlled outlets
  • Has an AM/PM indicator
  • You have the ability to schedule light modes for the timer manually
What we don’t like
  • The display isn’t backlit, so it might be hard to read what the display says in the dark

❷ Nearpow Timer

  • Made to suit any wall outlet in an indoor location,
  • It plugs into a 120V grounded receptacle and is rated at 15A/1800W
  • LCD display has a digital timer
  • Has a mechanical life expectancy of 2 years
  • The shortest time interval is 1 second
  • You can have 3 different timer groups at the same time

The Nearpow is considered to be one of the best 2-pack deals that you can find on Amazon, but let’s see how this light timer performs and does it deserve to have that title.


When you buy the Nearpow grow light timer, the box has two timers inside, which is already a benefit in itself.

The most recognizable thing that draws attention to this grow light timer, is definitely its display.

On there, it clearly shows when it was off and when it was on.

This feature is actually not something that you find often among timers.

Made out of insulation material, and a child lock function as well, the Nearpow digital timers are very safe to have around.

Because of the very well-loved clock setting, these light timers usually end up being very cost-effective and could save you money and energy.

One downside is that the plug itself is very big, so the buttons and the writings around them are on the smaller side, so it might be a bit of a fuss to read what they say.

What we like
  • Getting two grow light timers at the usual price of one grow light timer
  • Nicely sized LCD screen
  • Easy to be programmed correctly
  • The digital screen shows the exact time when the timer was on and off
  • The option for having multiple timer groups, and not overload your electricity
What we don’t like
  • The display and the plug take a lot of space, so the buttons ended up being quite small
  • If you have a socket with 2 outlets, this device can cover the outlet under it, so you couldn’t use both at the same time

❸ VIVOSUN Digital Timer

VIVOSUN Digital Timer
  • Well thought out design, and easy access to the timer settings
  • Made out of extra fortified plastic
  • You can have up to 8 programs during a 7 day period
  • It has a very small built-in battery, with a battery backup

The two separate outlets are the main selling point of this device, and if you have many electronics in your greenhouse that are always on outlets, this might be a reason enough to opt for the VIVOSUN 7 grow light timer for your grow tent.

But, before you make the final decision, let’s see what does the review says.


This programmable timer is designed for plugging in a grounded outlet.

The infamous two outlets are 3 prong outlet receptacles.

Like most timers, this outlet timer has an LCD screen that shows how long it has been on.

You can have manual timer options for this one, and the 7 buttons in the front are used to program your schedule.

We know that the question of power outages is an important one to consider when buying this type of device, so it’s good to know that the Vivosun 7 is made with a standby feature, meaning that it has the ability to cut off the power completely from all connected devices, if a power outage happens.

As the outlets are on its sides, you have plenty of space for buttons and it’s quite easy to program it and set up the automatic settings you need. It is also battery-powered with a small built-in battery.

What we like
  • Double outlets
  • Big LCD screen and nicely sized buttons for easy programming
  • Made out of hard plastic making it almost unbreakable
  • Great price
What we don’t like
  • With two cables sticking out from the side, this outlet timer can take quite a lot of space on your wall

  • The operating voltage is at 125V, with a current rating of 15A
  • It is a plug-in mount, and it doesn’t take up much space
  • You can program it to turn your devices on and off for intervals as small as 30 minutes

If you prefer mechanical timers and are not a fan of automatic timers, then you should look into this one to use as a timer for grow lights.


The BN-LINK BND is the most basic and classic outlet timer.

It’s one of those manual timers with a dial and an arrow that you’ve probably seen before.

However, the simplicity might be exactly what you need, making this the best grow light timer that you can put your money into.

This could be a great timer for grow lights if your needs are simple and everything you require from the grow light timer is the on/off functions, without any other specific settings for the cycle.

Each one of these has a single 3 pong outlet, and as most mechanical timers, it plugs into a grounded outlet.

What we like
  • Small and compact
  • Simple to use
  • Inexpensive
  • Water-resistant
What we don’t like
  • It’s not highly programmable since it’s a mechanical timer

❺ GE 7-Day Programmable

GE 7-Day Programmable
  • 4 of the outlets are programmable, and the other 4 are always on
  • All of the 8 sockets are grounded outlets, making this a very safe
  • Ability to store and execute 7 days worth of programs
  • It’s UL listed and rated at 120V/15A/1800W 60Hz

This one comes up as a favorite if you are in need of a power strip.


If you have a lot of grow lights in your grow tent, in combination with plants in the flowering stage that need to be taken care of, using a power strip could be the right choice for you.

Also, there might be more things in there besides the grow lights.

It looks like a basic power strip, but, as you would expect from a digital timer, it has an LCD screen.

Said screen shows the time when the digital timer was on, and also there are seven buttons meant for programming whatever kind of schedule you need.

It has 8 outlets, which are not all the same – 4 are programmable, and 4 are always on.

This could be extremely useful in a greenhouse, as there are usually many more devices there besides the grow lights.

What we like
  • Made out of heavy-duty materials, making it very durable
  • A lot of sockets for the greenhouse
  • Safety covers
  • Great as a surge protector
What we don’t like
  • The price is high

Canagrow Digital Programmable Timer
  • This device can store and execute up to 20 on/off programs
  • Child lock function
  • It has a Random function
  • Rating of 120V, 60Hz, 15A/1800W

This grow light timer is very loved among people whose main interest is growing Cannabis specifically, but even if you need a timer for grow lights for any other kind of plants, the Canagrow may be a great choice.


The main benefit of using this for your LED grow lights is the fact that it has two outlets, making it very practical.

The design of this timer is very straightforward and simple.

The screen is of course an LCD one, and on it, you’ll be able to see the time, day of the week, as well as what mode is it currently on.

Its display is also one of the great features of this device, as it’s very big and nicely colored, so you won’t have any problems reading from it.

  • It has 9 different modes
  • The size of the LCD screen and buttons is great and everything is nicely labeled so it’s easy to program it

What To Look For When Buying A Timer

As you can see, there are many different kinds of timers that you can choose from, so we understand that looking for a timer for grow lights isn’t an easy task.

Down below, we’ll list some of the most important things to consider when you’re buying a timer for grow lights.


The main thing that you should consider is whether that specific device is going to work for your specific needs.

Think about what plants you have, and what kind of a schedule they prefer.

Also, you should know how your plants react to the grow lights, and when you crack their routine, you will know how much grow light they need.

Depending on that, you’ll know if a high-quality timer with lots of functions is what you need, or will your plants do with a simple one.


You will probably spend a lot of time looking at the LCD display, so you need to make sure that the one you choose works well with your eyes.

Also, take into consideration how many led grow lights are there in your greenhouse, and whether you need the display to be well backlit if the greenhouse itself isn’t very well lit.

Another important thing is that you need to have in mind how many programs will you need for your plants.

Do you need more than 5, or is it just a simple one?


Of course, it’s very important to consider how much money are you willing to invest in this.

If indoor gardening is more than just a hobby and you have money to invest in this, then it might be useful to splurge a bit.

If, on the other hand, you need it for just a few plants that you like to have around, going for a cheaper option might be a better choice.

Also, do you need only one timer for grow lights, or does your greenhouse have many led grow lights that will need a lot of the timers?

Should Grow Lights Be On A Timer?

Finally, this is an important question to consider before you even start looking.

The answer is mostly yes.

The reasoning behind this is that firstly, LED grow lights should never stay on for the full 24 hours, as that can result in the opposite of what you would want to achieve with grow lights.

Your plants won’t know the difference between you manually controlling the lights and the natural sunlight, and a grow light that has been automatically programmed.

And, since you most likely have a life separate from the plant, you probably won’t have the time to always be right on schedule.

Most plants love their schedules, so having something that will help you in with plant care could only benefit both you and the plants.


How many hours should grow lights be on?

This mostly depends on what kind of plants you have. What’s the same for all plants though, is that they don’t like being in the lights 24/7.

Your goal is to replicate nature and make it a tad bit better, and nowhere in nature do plants have 24-hour long light exposure.

However, if you have edible plants, most of them need around 14 to 18 hours of light per day. They should have at least six hours of darkness, too.

Should grow lights be on during the day?

This depends on how much light you get in your grow tent. Plants like vegetables need around 16 hours a day in light, and 6 to 8 hours in darkness to rest.

See how many hours do your plants get from sun exposure, and then just add the light from the grow lights in order to reach this number.

If your greenhouse is in an environment where there’s not enough light during the day, then you will need to turn on the grow lights even during the day. Also, if the weather has been foggy for prolonged periods of time, you will need to use the grow lights.
