:lol: Not important to "blow carbon filtered air" at all.  That's just silly. 
As far as air movement is concerned, you do want an oscillating fan or some other method of moving air around your plants to keep them moving and help them develop strong stems.  If you have a good exhaust, and a clear intake then the temps in your tent should be okay.

Harry: when you were growing with the tent, did you just set up the fan exhaust, and do the passive intake? Are there pictures of your setup somewhere?
My grow space just got a whole lot smaller (as in about 2x2) and I'm trying to figure out the best way to use it.  Might be my first ever SCROG grow!

yep, I had a 95cfm squirrel cage fan that I had sealed on the exhaust, and then I left only one of the 2 velcro windows open and one of the weird little drawstring sleeves on the opposite side for maximum passive intake.

I found that that arrangement actually created enough wind inside the tent that I didn't even need another fan inside. the passive intake facilitated evapostranspiration, it was magnificent




In the 2x2 how many plants did you have going?
I can't recall if you had a grow log...link if so?
good to hear that you were able to create enough air movement with just the passive.
To clarify then, you didn't duct/air cool your light; temps were controlled by the exhaust fan+passive intake.
Do you think its wise to max out the wattage inside the tent at 600 or could she handle a 1000w setup if you had a higher CFM fan?

hahaha...I don't know why I put the 1000w question out there, I keep thinking of my 4x4 space.
So, you think too hot with 600?  I'd love to see some great yields from that space, and I don't think I'm passing the point of diminishing returns with 150w per sq ft do you?
400W would give me 100w/ft^2 so maybe that's my best bet.
Just thinking out loud...I don't want to do a CFL grow, I like the results from HID too much.

These are my final plans.� My only concern is the position of the carbon filter and the length of ducting used. There is also going to be an oscillating fan not shown in the pic.1) Will the 449cfm Vortex fan work well enough for passive ventilation and light cooling despite the sharp bends in the duct and its length into the attic?� I want to place the fan in the attic to reduce noise, my room is next to the front door.:grin: Should it be inside the tent?2) Noise reduction ideas? I was going to stuff foam or something into my windows but was wondering if anyone had any tips to muffle noise without sealing the room and probably making it real hot.3) Is the carbon filter ok there, over the light?




I would personally put my fan and filter together.  You mention passive ventilation, but from your sketch it looks like the grow room is a sealed environment...where is the air coming in?

DJ, your LIGHT-->Filter-->Fan would be fine.  Just make sure that your tent is still light tight with the holes open.

Please don't use 1000 W in a small space like that. No matter how much ventilation you use, shortwave infrared energy from a 1000w bulb will burn/kill the plants in no time. .




Asinine. I've literally seen 2000w HID grows run over a 4x4 space and the only thing that happened is INSANE yields. Please ignore this guy.

I don't know about another squirrel cage/computer fan, it would make more sense to me to just use one fan but with a higher CFM...
The oscillating fan is handy to keep the plants moving, and to prevent bud rot, and assist in transpiration by lowering humidity in the room.
