jaydee84 Reviewed by jaydee84 on . Question about lighting schedule fluctuations I have been fairly lax on my lighting schedule in flower. I like to do lights on at 3pm and off at 2am. Sometimes I fluctuate + or - 1 or two hours on or off (never more than 11 hours of lights on though) So basically I have a range of + or - two hours. Is this bad, and what if any thing will it do to my plants. They are in week 5 of flower and look beautiful, but I think the main colas are a bit tall and maybe a bit thin. What do you think?
