My first attempt using a tent and 600 watt HPS/MH bulbs went terribly wrong and I just recently restarted growing on a lark and had a second very successful grow; the buds were (and I'm a chronic smoker) kick ass! The downside of #2 grow was that I trimmed when I should not have made rookie mistakes that could have been helped or eliminated had I read a little more and spent more time researching. So now, we are in the first week of flowering for grow #3 and I need some help!
