That's what I'm thinkin' too.. When I pull the root ball after chopping, the root system always looks pretty healthy. My general rule has been not to screw with them once in flower with the exception of regular cultivation of the soil at the top of the containers and staking when I have to if they can't handle the weight of the buds.

I think compared to others I don't grow in very large containers either. Just recently I've started to move up to #3 from a #2 for an experiment. With Kush in #2 containers I generally get 2.5 oz trimmed bud from each plant under a 1000 watt HPS. Based on .5g per watt, I should be getting about 500g per cycle and if you consider the amount of trash (trim and lower buds), I'm close. We'll see if there's a significant change going up one container size..

I'd still like to hear if anyone is repotting during flower and why you did?
