My lovely ladies are getting too tall for my ceiling!!! They are 4 weeks into a 12 week flowering cycle and I have already raised the lights as high as they go. I gave them bushmaster last week and it slowed the growth but I don't think it has stopped it. What do I do know? Do I absolutely have to top them? How much should I cut off? Just until they are no longer in heat or do I have to cut more to allow them to grow? Should I just determine the maximum height and keep topping as they exceed the limit? Please help.
