the only way you are going to get better bud size is with ideal grow enviornment and to use a bud promoter and hardner prior to flower cycle.Ok, so i'm in the last few weeks of flowering now. Probably about 2 weeks to a month from harvest. I am using cfls and I'm on a 12 12 cycle. I was wondering if I switched the light cycle to 24 hours for a few days, would this increase the bud size.
