Brainstorming ventilation ideas

Alright so I'll be growing in a dresser about 2.3' wide, 1.2' deep and 3.35' tall.(3.35cf) I plan to go scrog with 2 plants, so this will be just the right amount of space. here's how ima do the lighting: a 270w son agro will mount at the top, under the light will be 2 layers of 1/2" thick tempered glass, with a 1/2" of air between the two. They will seal the light from the grow and there will be 4 cpu fans that are about 40cfm each, 2 of which will sit low enough to cycle air from the buffer layer between the glass. What do yall think about that? I dont expect very much heat.

So for the grow chamber I'm really trying to figure out if I can run a closed system, because I'm using co2. I'll use 2 inline 4" duct fans(about 65-80 cfm each) for intake and exhaust and a 4" carbon filter for scrubbin. They will route thru the wall to a neighboring dresser and loop right back. How can I control heat and humidity? Im not asking for the fundamentals I got that, and no shit itd be easier to run it open that doesnt matter. But this is a small set up and with what I'm doing for the lights and because I have way more airflow than I actually need in the chamber I figure that alone could keep temps where I need them(which would be around 85 for co2 right?). I'll also have 15-20 of those same cpu fans( found em cheap ) place interchangeably along the walls to evenly blow shit around.

Has anybody ever done anything like this? believe me I searched.

I doubt I'll have heat issues but I'd love your input
What Im really worried about is humidity


??

nobody????

Are you running an enclosed hood? Is that what you're saying about the glass, I'm really stoned and am having a hard time picturing this...

Use a fan! Hahaha
Seriously fans and a cooltube hood!
Best of luck to you bro

If your plenum dresser can dissipate about 100 watts of heat under the most adverse conditions you expect ... you should be good. The air in your DIY double-glazed light hood ... to where will it exhaust? cn

I love the name by the way

I also am having a hard time picturing this, but from what I think your saying about the co2 a closed system would be best

picture it like this( shit im baked 2 haha), the light is at the top of the dresser, which is a rectangular prizm.the fans for the light are in the back of the dresser, they are seperate. the grow chamber gets sucked in to a minichamber that will have a Eva-Dry EDV-1100 dehumidifier and a equally efficient humidifier, they will be hooked up to some sort of humidity control ill either buy or make that will kick the dehumifider when its 60% and the humider when its 40%.(theyll both stop at %50)

The question is do I need AC to keep temps down or do I have enough airflow? If you cant understand that we'll have to revert to smoke signals

What is the smallest possible portable air conditioner a man can buy?
