A grow light timer decreased the workload of the grower, allowing for automation of lighting in the indoor garden. Without a digital light timer, cultivators often find themselves feeling chained to their garden. These allow for more freedom, and cut down on human error by establishing consistent light periods.
If you are looking to optimize your grow room for 1 or 2 lights, these timers will be perfect for you. If you are outfitting a larger indoor garden, or a commercial greenhouse, you will be better suited with a grow light controller.
When selecting an indoor light timer for the lights in your grow room, it is important to consider the electrical system in the garden. There are timers with 1-2 outlets, which are perfect for small, hobby grows, and there are timers for larger grow rooms with 3-10 outlets. This will come down to how many grow lights you plan to employ.
Supply voltage of these grow light timers ranges from 120 Volts to 277 Volts. Most small household grow rooms will use a 120 supply Volt, but some larger operations will require the popular 240 supply Volt.
Deciding which timer is best for you will also come down to the features you want included. Photocell allows for more automation of other components of the grow room that work on the same schedule as grow lights. For example, a timer with photocell will shut off exhaust fans and CO2 generators during the lights off period, and reactivate all necessary equipment when the lights come back on.
Some indoor light timers are required to be hardwired directly to your electrical system, and you should consult an electrician prior to installing these. Other features to consider are:
Plants will need different light cycles depending on the stage they are in. A general guideline is:
