Below is a comprehensive guide to getting you started in picking a suitable brand for your needs.

While we have the top pick in this guide being the BN-LINK 24 Hour Plug-in Mechanical Timer, there are various other models in this guide for you to consider. Before we get started, let us look at some factors to consider when buying one.

Buying A Grow Light Timer

There are various key factors you have to consider a grow light, especially since growers often have different needs. Below is an informational guide:

Benefits of Using Grow Light Timers


Timers make up for excellent solutions to control lights in your garden, which is an important resource for plant growth. With a timer installed, your lights are always ready to function when the plants need them, even while you are away. For instance, you might be asleep, or perhaps away on a business meeting. In such a case, the light timer will calibrate the lighting in relation to your specific preferences. 

Safety and Security

You can use these resources as a mechanism for keeping your home safe. How is this possible? Well, most high end grow light timer brands include the vacation function. It’s a feature that such brands include to give the impression your home “lived in” when you are not home. The mechanism works by activating the light at specific times or responses to stimuli such as movement. Therefore, it makes up for an excellent way to deter criminal activity. 


Rather than leave your light on throughout, such as when you are out on vacation, it would be good to get a grow light timer. It’s a mechanism that helps you save up on extra cash by activating the lights only when the plants need them. Furthermore, these tools often feature special sensors that can adjust the intensity of the light to suit your plants’ specific needs.

Plug-in Timers vs. Direct Wire

Plug-in Timers – these types are simple to use and can be installed using DIY techniques. You just plug the wires into a socket, and directly to the grow light you want to control. Usually, this type lets you control one or two devices.

Direct wire – these types might require some experience of professional installation. Why? Because they require direct hardwire installation. They let you control several devices and offer access to several programming functions.

Types of Grow Light Timers

  • Mechanical- These types leverage precision clockwork to function. Usually, you set these types by adjusting a dial, which works in the same way as a kitchen timer. Plus, you can use it to operate devices such as lamps, grow lights and more
  • Digital Timers – technology has made it easy to customize the functions of grow light timers. Not only are these types simple to use, but they also have various unique features such as programmable timers. Also, you can expect LCD screens to make things convenient.
  • Photocells – a photocell is a special component that can sense and adjust to light changes in the environment. Thus, grow lights with photocells will automatically adjust to your preferred settings for the best results. 

Features of the Best Grow Light Timer

  • Outlets – a good grow light timer should provide at least two outlets through which you can connect the grow lights. 
  • Programmable functions – are you leaving for a vacation for a long business meeting? Well, then consider getting a grow light with programmable features for your convenience. 
  • Ease of use – some high-end brands let you customize the timer’s functions in relation to specific time factors. These include week, hour, minute, and seconds. Plus, they are also easy to use and can meet your particular preferences for plants.
  • Material construction – remember to go for a grow light that has a heavy-duty construction. You are likely to move it around, or might be exposed to elements such as moisture or dust over time. Thus, it should be durable enough to withstand such issues.

Brand manufacturer – choosing products from the right brand ensures you get the best value for your money. Some top brands to consider when it comes to growing light timers include BN-LINK, NEARPOW, and VIVOSUN.
