Grow Room Airflow Question

[QuickGreen]

I was planning a DWC ScrOG grow with about 150-200w of cfl lighting. The grow room will be my closet and the space doesn't have the potential for intake/out fans. The space is 3'x2' and 10' tall. I was thinking I could get away with just having 1 fan (like a Honeywell Whole Room Air Circulator or a Vornado) at the top of the closet as my airflow. Doesn't sound too good of an idea but I don't know what else to do. Can I get some advice?

You need ventilation. Your plants will need to breathe. Perhaps you can make a false door behind your closet door and put an intake at the bottom and exhaust at the top. Use the existing cracks around the door. Or open the door slightly and cover it with a tapestry or something.
You may get lucky and not "need" ventilation, but your plants will love you more for it.

Thanks for the response. Would a CO2 tank work so my plants could breathe?

im no pro, but co2 and the ventilation are two different parts of the machine. You have to be able to vent that co2 out!!! so co2 would mean you need ventilation even more so...i think

From my experience with CFL's is having enough of them it still gets pretty hot and to have them being on for 18-24 hours a day its gonna get pretty hot. You got a bigger grow area than mine but i had som major heat problems from using 6 CFL's got up to 100 degres at times, then again i had a small cabinet. But im just throwing in my 2 cents. I'd say if you absolutly cant vent at least put in a circulation fan and if it gets too hot get some plexiglass and put it right below your lights to cut off the heat from filling the parof the oom where the plants are.

Got a question tho. How many plants you plan to have in tis space?
and pics would help.

sorry for the repost, but i think as long as you opened that door a couple times a day if possible you would be just fine in that amount of space. I think co2 for your area is over kill unless your ballin homie (for a closet anyhow). its kinda pointless to go that in depth if you cant have a decent ventilation system.
Have fun, Good Luck!~

Sorry bout the shitty cellphone camera!

Thanks for the info bro. I posted some pics above, and i have about a .7" crack on the bottom of the door. I was thinking of making a wood base for the closet and putting two computer outtake fans on the base, in addition to the circulation at the top. You know wat im getting at? Thats about all I can think of, do you have any suggestions?
