Defoliation only stunts growth and is not needed. Its been proven to do so.Speaking of defoliation, after flipping to flower , when should a grower do this ?
Which week if your looking at 6/8 weeks of flower ?
On that note: Only do it if it suits your grow style or in my case, to keep from bud rot and mold because its packed so tight.
You want to do it after the stretch which is 2 weeks.
