Air Circulation

So the lighting I'm about to order doesn't have any ports for ventilation, so I have a little question ...

Would it be a good idea to buy, say, 3 small fans, and rig up something ghetto like this



or just to have a couple fans moving air in there with some co2?

it would be bare minimum to work with but not a good idea if there is any chance to do it better;) see, the problem is not only to keep air moving in there but get fresh air in and moister out of the grow...

say, do you grow in a entire room or just in a closet?

You would need to run something like this through into another space/room to exhaust your old/stale air.



Suncourt 8" Inline Duct Fan Rated at 500 cfm (cubic feet per minute)Tried and true tools for the heating and cooling trade, wisely adapted for cooling grow light reflectors. An Inline Duct Fan is a reliable and cost effective way to keep temperature in the indoor garden under control. Use one fan per light or to increase the efficiency of an exhaust system. These economically priced fans have a lesser cfm (cubic feet per minute air exchange) than the high output CAN-FANS also available on this site. Perfect for air cooling a single lighting reflector or ventilating a small closet sized grow room.

Remember the more air movement (and this does not just mean moving the stale air around) the better. Bring in fresh air and exhaust the old.

See, thing is, this grow will be in a (closed) closet, and I cant make any holes in the doors or anything like that. :neutral:

So you don't own this property? Renting?

Well you do have the space underneath the door to suck air in. That is your intake. I don't know exactly what you have to work with.

Always provide air circulation and fresh air even during the night cycle. All the air indoors should be replaced every 5-10 minutes. Those are the tip top best conditions. Which we all should be striving for.

Yup, renting. Should I just crack the door open a tiny bit 24/7? A proper exhaust/intake isn't really viable given my situation :cry:

Well you would be surprised with the door cracked and a good fan right by the crack how much air you can pull in there.

Had an idea. Is this a sliding door or a door that swings open?

If it opens and shuts like a regular door there might be a solution after all. But it does involve a little cutting into the wall.

In my house everything is sealed so tight that there is a small register like vent above my door. Like a floor register cover but more narrow. This vent allows air movement even when my door is closed.

When installed this looks like a professional job and part of the home decor.

Looks solid, but I simply can't modify this property at all :?

Would co2 alone be enough or is that absolutely out of the question?

The exhaust and intake can't both run or blow into the same tube and is that the plan?

That's basically the plan, but I'm guessing there's no point to having it since I need "new air" and this would basically recirculate "stale" air? Anywho, I'm going to purchase the 400W with the hood that comes standard
