24 Hour Optimum Segment Timer by Grasslin
Unless you want to be in and out of your grow room every time your lights need turning on and off, a timer is an absolute necessity. Grasslin Timers represent the best that money can buy and are definitely a worthwhile investment for every grower. Make sure that you protect your timer with a contactor if you intend to control HID grow lights. Getting your grow room timer to switch on an appliance for the right time and duration couldn't be easier! Just do the following: 1.) Ensure that the timer is in the manual override mode and that the arrow points to the correct time. 2.) Select the "on" period(s) by pushing up the relevant 15-minute time segments on the dial.
