in dw's part of wv we get on our 4wheelers,play crash test dummies on ice.2 wheel drive and 700 cc's +ice = fun fun fun.Anyways i wanted to buy the old wally world 100 watt mh security light for my small veg box,instead of cfl's.i'll cool tube it and whatever.well i think it would be better with mh than cfl,my opinion anyways.I flower with 400 watt hps on 12/12 and my 250 watt hps kicks on for 6 hrs. (middle 6 hrs. of 12/12 cycle) My idea use the 250 cause i got it,and to simulate mid day sunshine.so all mh input is helpful.thanks.
