Yes that is fine to veg if you have a hood that can direct the light to cover the area. As for flower HPS is what you want I would suggest 1000w just make sure you have a large glass bottom hood to deal with the heat.
Zandor Reviewed by Zandor on . first grow this is my veg room runnin a 400 halide. the dimensions are 6ft high about 3.5 ft wide and about 5 ft deep growin some bagseed right now but a buddy of mine has got some humbolt clones he is gonna give me. my question is do you think 400 is enough to veg 10 plants and what would be my best choice for a flowering light for the ten plants maybe 15?
