Timers

Your grow room may go 24 hours, but you can’t. Our timers can. Timers turn your pumps, lights, fans, air conditioners and dehumidifiers on and off. Some detect when it’s night or day in your grow room, and others work with apps on a smartphone. Learn More

Find a timer that works to fit your schedule and needs. Need a timer for just one device for just an hour or two at a time? We have several. Need one that can control a single light, or a whole bank of lights? Find one here. You’ll also find timers on these pages that allow you to set a cycle and repeat it automatically.
