Ventallation Question

[midnitetokker]

Ok, I have my new cabinet that I am going to use as a garden. My only question is where I should have spaces for ventalation. I am guessing that since there are two sides, I will need two vent's for outgoing, but where should i put them? On the top, or towards the bottom? Or does it matter? I will be using duct fans to push air out (and in, i suppose), so I will have a bunch of 4" holes when its done.

Anyway, can someone take a look at the unit here and give me an opinion?

Thanks

Yes, it definatelly matters.

Heat rises, so putting the active (fan forced) exhaust up high, is best.

Passive (no fan) intake near bottom, but be careful of light leaks from both. Not necessary to cut that big of intake holes. You can likely get away with smaller. (2")

You'll need a circulation fan for inside the cabinet, too. (exhaust and intake don't work well alone, so additional air circulation is needed.

Have you taken a look at other wardrobe conversions, for guidance?

[midnitetokker]

No, I really haven't. This is more of a hybrid of my closet attempt and a grow box...on a larger scale. Do you have a link to a decent wardrobe conversion post?

[midnitetokker]

You can likely get away with smaller. (2")

Also, if I can get away with smaller, what type fan(s) would you suggest? The only one's i can really see are the 4" duct fans from home depot, but am definatly open to suggestions

[Rusty Trichome]

Fans on the intake are unnecessary. The suction caused by the exhaust fan(s) will pull the air in just fine.

so I can get away with a few little slits towards the bottom then? I am a n00b in this, so any help is appreciated.

[Rusty Trichome]

I don't see why not, if you can keep all light out, and it doesn't restrict the incoming air. Do you have plans for keeping the light from entering thru the doors? Step inside and close the doors...If you see light, it will need to be addressed.
Don't lock yourself in, tho. :thumbsup:

[midnitetokker]

Yeah, I have a thick black painters plastic sheet that I am hanging in front of the doors. That way, you have to open the doors, then open the plastic to have access. All other little holes will be covered by tape when I am done with cutting the new holes (not the vent holes, I'm working on figureing out how to make those light proof as well......)

[Rusty Trichome]

Perhaps putting them in the back of the closet, and keep light from getting back there...?

[midnitetokker]

I was thinking. If i take an air duct, and make slits in it, and extend it the entire length of the area, (similar to the concept of an air conditioner), would that work? in other words, have a hole where a duct comes in on the bottom of one chaimber, then the duct goes to both chaimbers on teh bottom, then take a knife and make holes in the ductwork. That way air can get into both sides, and minimal (if any) light issues. I suppose the same would work on the outgoing air holes as well....except with two fans on top (one on each side, pulling air out both ends).
