[quote name='"Dr Hoops 23"']Is it really necessary? (air cooled hood)[/quote] Absolutely since you are growing in tents. Wings are more for when you have an actual room. Trust me on this. I think the air cooled ipowers are only like 30 bucks more. I have 2 ipowers sets btw..1k and a 600.You can also get your lights closer to the canopy...in turn getting more useable light for your wattage dollar.
