A:a 400 watt hps with enhanced blue spectrum is more than enough for seedlings.....what you need is a couple floros for the first two weeks from seed.....check my fotos in basic growing......i have posted my ladies' pics in week 5 from seed, week 4 in veg......they have been grown from the beginning under a 400 watt hps grolux.....
B:if you insist in trying to cheat your fathers' ability to detect marijuana plants, then try to grow tomatoes next to them
