i had to supercrop my last grow of sourcream as i started to run out of room.. i was super nervous doing it, but watched a few videos on youtube, and got a feel for what i was doing first.. i did it right when the lights came on and when i woke up in the morning, they had totally recovered.. the bud that had been laying down that night was now standing straight up looking at the light.. i couldn't believe that she recovered so fast and really took to it well.. i even did it about two or three weeks into flower as well, and it didn't seem to stress her in the least.. and i think i gained about 18 inches in height from the one supercropping..
