Well Denni,

Yes a 400 can make a big difference in growth. Personally, I veg with the 1000 watter. I'm not sure why you are not vegatating them 24hours a day but what ever. How far you keep it from your plants depends on if you have an aircooled hood or not. Aircooled 24 to 30 inches from the plants is fine. No aircooled hood you should be about 36 to 48 inches from the plants with an oscillating fan being a must. Are you cool with that?
