hygrozime is the best i use it too most on here will say don't cut anything in flower stage as it can turn hermi but stinky said she takes clones early in flower sometimes so and i myself have taken a couple within the first week and it did nothing to my plants and i trimmed them up through out the flower stage and nothing has happened to mine so just be easy i would'nt take alot maybe 1 from each and u can grow them out and toss the males as u find them say u take 1 from each and label as what went with what plant and as u see sex on the main plants u can toss the ones that are male and the clone that went with it.eveybody has good safe info on here but i have found that this whole growing thing no one has it down 100% as iv'e done things that everyone has said to never do and mine are fine even down to how u start them i started all mine in the rr's under300w of cfl's in a dome and had 98% success everytime. but i listen to most of what is said on here and tweak it from there to fit u. as long as u don't go crazy with it.
