I'm giving it a go at hydro growing for the first time. So far I have left the full spectrum grow light on 24-7. Is it time to use a little less light or are the plants still at the stage that constant light is good?
6-7 weeks of 24 hr. fluorescents is good after germination. When I transplanted mine into hydro I had an 18/6 cycle when they were in the vegetative stage and then when they were in the flowering stage I went to 12/12.
