If you can conquer the heat issues, that's great but I'm wondering about the lumens per sq ft ratio. In the FAQ's it says to have 3000 to 5000 lumens per sq ft. With a 400w having 58,000, that's over 10,000 per sq ft. for youe cab. Maybe the more knowledgable growers here would have a better idea on whether that 5000 per sq ft number is accurate or not. Anyway, in the FAQ's it said you can bleach your plants with too much lite.
