My first time growing and plants are 2 1/2 wks old and about 8-10 in. I still have the ligts on 24/7. should i change that to 18/6? Also when do i change the bulb to my hps? ANY help is apprieciated!
first off the 18/6 is a veg light cyclto flower you have to change toa 12/12 light cycle.
the hps bulb is good for flowering. you could probule start flowering them when they reach 12- 18 inches tall. for more info read through the grow faq.
