wow first going into the home without a warrant and then coming back with it, after already entering the house and finding the weed. we all know he's gonna get off on it.
Re: 400 or 600 ??
actually, get a vented hood, and you'll produce some killer with that 600, but unvented hood i'd have to agree with dankN 400 will be plenty. must have grow room ventilation though.
i second that endo, your gonna yield piss with those lights. the only way to grow is to grow right. if your gonna grow, why waste ur time on a few grams, when u can go sink $100 in a 400W hps kit. and yield ounces..... just an opinion i know the locals share.
yeah u can burn seedlings easy, all in all, it doesnt take much to adjust it, your talkin about good quantities of the stuff, besides your supposed to empty ur res often anyway. ur not dumpin the whole bottle in there shit lol... dude u run a risk of burning plants everytime u put anything in...
