Ive got 2 barneys farm red cherry berry in veg at the mo, they are 3 week old,both 6inch and very bushy,ime just about to top them. My question is when is the best time to trim all the undercarriage,and how much can you trim without causing too much stress to them. They are in coco and under a 400w hps.
This is my 4th grow so still new to it and just after a few tips. Ive never trimmed b4 but wish i had when it came to harvest, what a ballache!!
many thanks.
