I beleive its only 3x3.the maximum lighting area that a 400 watt HPS can light is 4x4.
my closets about 5 by 2 and i have 1/2 blocked off right now to conserve the light, but its worked great and the plants are growing awsome. Btw, htg has a 1 year warranty on the bulb and 2 year on the ballastI will measure when i get home ,but I have the plants close togather in medium/small pots.Heres the other light from the local shop wich one is better, http://www.gchydro.com/Aluminum+Wing+Grow+Light+Package+-+HPS|MH+400.html Can some of you guys give me venting ideals,Will these grow fine in a grow tent with fans in a room with the window open?Righ now I have my 6 clones in a outdoor closest that i keep cracked with a fan when im home stays at 70 degree
Im going to buy that bulb that was the best price i found,Know i just need to figure out the best place to flower my babies ,closets or grow tent,I have a huge outside closest that i vegg my plants,but its built like a vault no way to vent with the door closed i the think they will burn up in the with a 400 watt in theremy closets about 5 by 2 and i have 1/2 blocked off right now to conserve the light, but its worked great and the plants are growing awsome. Btw, htg has a 1 year warranty on the bulb and 2 year on the ballast
