I am currently using 4 foot parabolics. I liked the light spread on them, but heat is a semi-issue. If I had to do it over I would go with 4 of the air cooled hoods by sun system. Think they run around 200 each?
I will for sure. I didnt realize the heat produced by 3x1000w lights. If I just got 4 air cooled hoods from the start, I could run 4000w closer to my plants with less heat.
