Relays and Contactors
Because of the high wattage used with grow lighting a contactor or relay is needed to switch the lights on and off when used with a timer or the high wattage can melt normal timer contacts together leaving your grow light stuck in the on position risking flowering plants reverting back to grow because of the constant light on hours.
Hytec Hydroponics sell many different types of relays and contactors some with inbuilt timers to control your grow lighting hours without any risk of over powering any weak house hold timers and risking electrical fires.
This grow light timer is ideal for controlling the on/off cycle of one 250W to 600W lamp, perfect for use in a smaller grow tent for example where only one grow light is necessary.
