hey folks just got a quick question about trimming, i have 3 400 watt hps lights over 45 healthy females, im doing a hempy style grow using 2l pop bottles. the area i have is narrow so im trying to find a way to trim them so they just focus more on a big bud shaft rather then branching :s.. any help would be great thanks p.s. im using GH nutes grow,micro,bloom.
