If you're already going with a 1000W Bulb and not getting any heat problems then yea MH is the way to go for vegitation. However, If the grow area isn't too big, then look into those T5 lights or whatever. I was told they can veg better than MH simply due to the fact that they can be put a lot closer without burning the plants. But then again, I think you probably have a larer area your trying to grow in cuz you're using 1000W.
