Best Timer for Grow Light: Buying Guide

There are several timers you can choose. However, you need to be selective to choose a model that will be safe and reliable. Here are a few features to consider:

Mechanical versus Digital

Mechanical timers are simple mechanical devices that are made up of a mechanical clock and a few mechanical switches for starting or stopping a system at a particular time.

Most manual timers on today’s market are fitted with a control knob/dial. All you have to do to set the time is to turn the dial.

These timers tend to function similarly to mechanical alarm clocks. They feature a mainspring that operates the device.

When compared to digital timers, manual designs can only manage a limited number of zones. They may be suitable for grow lights, but inefficient for more complex appliances.

They also don’t function during a power failure. So, you have to reset them every time you have a power outage.

They are still manufactured, but their popularity is fading as new digital devices with enhanced convenient features are added to the current market.

A better solution for indoor growers lies with the modern digital timers. Unlike their mechanical counterparts, digital models come with LCD readouts and an array of built-in functions.

Digital versions are fitted with control buttons that are easy to navigate. All you have to do to program the timer is press the appropriate button.

The most contemporary digital timers allow you to program settings for different days of the week. They are the perfect choice for those who like to sleep out on Friday night.

You will even come across digital models that allow different weekly patterns for different times of the year.

Plug-In versus Direct Connection

Timers for grow lights are sold in two major designs: plug-in and direct wire connection.

As the name suggests, plug-in models do not need any installation. All you have to do is plug them into the wall socket to power.

On the other hand, direct wire connection needs a hard-wire connection/installation. They allow you to control several devices and offer extra programming options.

Special Features

The essence of having a timer is to program you to grow lights to function in an organized manner without you being present.

One of the virtues of a high-quality timer for grow lights is time setting. The unit should be twenty-four-hour or seven-day programmable.

The finest digital designs are capable of controlling up to twenty groups of on/off switches. A convenient model should provide you with several timing combinations.

The timing combinations can be a group of weeks, weekly, daily, or hourly. You should also pay for a device that has automatic repeat weekly settings.

The most recent digital timers come with a manual override button that allows you to momentarily operate the timer manually.

Another special feature that is found in digital designs is a built-in backup battery. This backup battery allows you to operate the timer without connecting to power.

Also, the built-in power source allows you to save your programs in case of a power outage or failure.

Another special feature that will most likely entice you to choose digital over mechanical indoor timers is silent operation.

Mechanical designs can be silent in the short-run, but after a considerable amount of time has passed, they will start generating a crackling noise that is quite annoying.

The number of outlets also matters the most popular timers are either one-prong or two-prong. Two-prong allows you to connect two lights and one-prong connects one appliance.

Final Words

In addition to a good grow tent and hydroponics system, your LED grow lights are a crucial aspect of your grow operation. FA timer is a lifesaver for any indoor grower. You no longer have to turn the timer on and off. You can program the timer to do exactly that on your behalf.

Quality timers for grow lights are not difficult to choose. For starters, you should always go for a digital design instead of a mechanical one.

Digital timers come with built-in backup batteries, seven-day programmable features, manual override, and vacation mode (in case you need to step away for a day or two).

The ability to control how and when your grow lights come on, allows you to provide your plants with sufficient light whenever they need it, even when you’re not around for a while.
