im going to be running 4 600 in the flower.
how many plants do you think i should put under each light. id like to use 3 gallon pots so i can top them and get a few nice colas.

also i hear about "a perfect room" "no in and out vents"

how does your room stay cool? is an air conditioner enough to cool the whole room with 4 lights going in the summer?

right now i dont use cooling but i have 2 carbon filters
1 going 24 hours venting straight up and another going 15 mins every hours venting out i have virtually no odor problems.

im going to be moving and just want a few suggestions

35 views and no one has anything to say?
i know its not the same question all the 14year old kids are asking about 1 light and wondering the basics but i thought someone would be able to help

a couple suggestions, i used to run a sealed room no in and out, i had a huge ac unit, and 5 x 1000 , and honestly it couldnt keep the room cool,

i was under the impression that it would be cool enuff, and no it wasnt, you can try but i wouldnt advise it, plus you ac running 24hrs a day$$$$$ aint cheap, check my grow i just went back to in and out vents, no sealed room

i would put 4 rows of 4 under each light mabee.. 12 -16 pr light

hope this helps...

i agree w/bayarea you need vent unless your only going togrow2 or3 plants. I'd say 12 plants per light in soil but if hydro i'd go more like 15 or 16 depending on your space/table size. also get some big ass fans you'll need 'em in a couple months

I would suggest running a loop through all of your lights, taking air from a clean/cool area coming in through the ceiling and through the lights and back out of the room. Then you can have a carbon scrubber hooked up exhausting air through the ceiling. You should be fine this way, even with 2400w worth of lighting.
