i would get a 3x3 thts there footprint pretty much..a 4x4 is like the maxxx for a 400w..
i ran a 400w a few grows ago in a 3x3 by 7ft tall tent with only a duct booster fan ($25 on amazon) venting from the top and bottom vents open always, and a fan inside mixing it up..temps never got over 85F...
ya i cant find the answer any where.. its says 110,000 lumens tho im just wondering if 3feet from canopy is gunna cause airy nuggets..thts where i keep a normal 1000w
So if this dual arc bulb has a 600w hps and a 400w mh..
does tht mean it doesnt get the penetration of a normal 1000w bulb??
does that mean i have to keep it closer than i normally would a 1000w?
