That makes perfect sense, happy growing.
Zandor Reviewed by Zandor on . Should MH bulb show light after power up? or does it need time to start light up for first time? it reads "time should be allowed for lamps to stabilize in color when turned on forthe first time. this may require several hours of operations, with more than one start. lamps may require 10 to 20 minutes to re-light if this is a power interuption.
