i would recommend using a cfl for start, no need to waste electricity on a 400mh for those. make sure that mh is atleast 3ft away id say, maybe more.
when u say Ima set them babies under a 400mh for about a week or so. Then change bulbs and start 12/12....so your saying your gonna flower them after they get 4 inches high?...lol..i dont get it...yes thats exactly what im reading. you need to veg them way longer than one week from where they are now. ...then next time around , start them with a cfl. 400w mh on those are a waste of money and light.
