I have a question about venting my cabinet , my flower space is 4 foot 5 1/2 tall x 1 foot 10 1/2 wide and 1 foot 7 deep and my veg space is 2 foot 3 x 1 foot 10 1/2 x 1 foot 7 deep. I was wondering if its possible to vent this cab with high cfm computer fans? I plan on using led and cfl and the main reason for the computer fan idea is cause I don't want some big ass exhaust fan stick on out the back, any help or ideas is appreciated.

None I can recommend from experience. I've seen an inline ozon generator being used as backup once, not sure how effective or suitable that is.

Good ventilation is essential regardless. You got plenty of space (the left side of the top storage space) to build in a decent exhaust to hide it from sight and silence it as well.

I like the idea but would I need to build that box if the fan itself was gonna be inside my cab? And I've seen cfl grows ventilated with pc fans and from my experience leds run cooler than cfls, I was thinkin I could have a couple running if needed but idk I'm open to ideas

"Need" depends on the requirements but if you turn part of that top storage into a box you can insulated the inside and don't need a separate box.

While you could do with less ventilation with LED heat-wise, you mentioned carbon filter in the pic and that needs a decent fan to be able to pull air through it fast enough to make it effective and still ventilate enough too.

Ok so the fan itself is inside the insulated box, is the carbon filter attached to the outside? Any chance you have some more detailed pictures? would help me alot

The carbon filter is on the inside of the grow space, you suck air through the carbon filter. Although, pushing air through it works too. Just stick with one method.

Ok so if I had the exhaust fan and carbon filter in my storage area , would I be able to use pc fans for the intake ? And also I was wondering is that foam on the inside of the box to silence it?

I actually had that myself, a large pc fan as intake. Turned it off one day and it kept spinning... it just works obstructive unless you have a weak exhaust. There's really not need for an active intake in a small space.

Soundproof foam.

Can I ask where you purchased the soundproof foam? Also any suggestions on an exhaust fan that's quiet?

Does that fan in your pic have a built In speed control?

You could use the fan/can to clean and vent the air from inside the box and the Ozone Gen to clean the residual air outside the box. That's what I would do anyway.

A built in thermostat, it has 4 different speeds but controlled on temp. If I set it on 19C it will run full all the time, if I put it on like 25 it will run slower till it exceeds that temp.
