yea, i think im just going to stick with the 400 for right now.. im so damn paranoid cause like i said its a 5 year deal if i get caught.. not that i mind pullin the time just gotta be smart about it..I have a 4 x 4 x 6.5ft tent and use 2 600w Apollo Ballasts and reflectors they work great and you cant beat the price.
ah right on bro thats a big change for me i normally get a avearage of 5 oz a plant when its oudoorsI grow with a 400 watt dual MH/HP in a tent close to your size,(just a tad smaller.) I grow 3plants at a time in 5 gallon SmartPots with good results.In other words great bud and about 3 oz each grow.
