Thank you for that advice, And I will keep it in mind for my next grow, But that doesn't really answer my question. I need to know if keeping the lights out for 24 hours or more just to sex quick is dangerous for my plants. I have had the light out for 22 hours so far and just took a quick peak without turning the light back on and I haven't seen signs of sex yet but the plants are still doing really good, none are wilting or anything, still standing strong. I was thinking about cutting the light yet again today for another 24 hours seeing if they sex. Any advice or opinions would be greatly apreciated!! thanks.:thumbsup:
