Hey guys, I am about 2 1/2 weeks into vegging from seed, I have 12 plants under a 400watt hps, 400watt mh, and 2 2bulb 4ft fixtures (flo's) sideways on the side of the plants for side lightning. They are 4-6in tall about 5 nodes for all of them, looking good with only a couple of probs/discoloration, anyways, I'll be flowering at week 4 or 5, so my plants don't get too big, however, I've read in a couple of different grow books, when I go 12/12 I will need COMPLETE darkness, no light in the grow room at all during the dark schedule or it will not grow big fat buds... Right now I don't use any ventilation other than my home a/c and leaving the bedroom door open 24/7, so I am thinking of adding a Suncourt 8in inline duct fan from HTGsupply for exhaust, it's suppose to be good for 500cfm, so I figure that should work, i'll still need more intake other than my home a,c from the floor, so I figure if I cut a hole in the door that would work for passive intake? I basically just want to know if this will work fine to grow my plants??? Also what if light is coming in from the other side of the duct fan??? Won't this fuck my budding process up?? How much light is too much during flowering (dark schedule). I'm growing a couple of strains from 2 diff bagseeds, so far one looks sativa dominant and the other looks indica ^_^. Very excited ^^!

I have my grow room, inside a room in a big wooden frame with black plastic covering around the frame itself, here is a quick picture I threw together on paint to give you an idea...

Anyways thanks for hitting me with some knowledge guys, I am just sooo excited about growing my own favorite plant, I want everything go smoothly, again THANKS ROLLITUP!, Take care, smoke, and be happy ^_^

if your using 8" exhaust then use the duct tubing to turn down away from the light.

and the same for the intake, but rather then one hole for intake (you want twice the dia. for intake ) make two 8" hole and use the ducting the same way.

hope this helps.

Thanks alot!! I'll for sure be doing this!
 
You'll want to look into odor control like a carbon filter.

12 Plants are gonna STINK towards the end.

A good stink - yes. But conspicous.
