I have a 8x12 room full and want to know if i should go 2 400 watt MH lights during veg and HPS during flower? Or should i use a 1000 watt light during both stages? Heat not issue what will give me best product at the end. What is the difference in 400 and 1000? Is it the area of light coverage or is it a better light for plant? Last question or those arch light good? You can use for both cycles right?
