LST it, may be the only way, but its not a good idea to be chopping the tops!

Is it just getting to high for the grow room?

If thats the case, then you should have concidered this, and flowered it early, as they double in size while flowering.
LIP Reviewed by LIP on . HELP TOO TALL Ok they have been flowering now for two weeks very little flowers but enough to know all girls and over 3ft. high and still growing . Should I start chopping their tops off to keep away from HPS? Rating: 5
