i have done it to about 4 of them but i think i have left it to late as they were about 10 inch away from light and my light wasrite at top maxed out it cant go anymore, the ones i super cropped have took about 5 days and now are bending back up about 5 inch from light, i have 4 weeks flowering left hope they dont grow no more mate, my light dont give of to much heat as my bulb is vertical,,,
