I have a question. I'm setting up a grow box, and the only issue I have is air flow. What i was thinking was having a fan/blower of some sort (like a stanley blower or a can fan - I'll definitely take suggestions here - lower costs preferable) and this leads through 4" ducting to a DIY Carbon filter. The exhaust i just described would obviously be mounted on the ceiling of the box.
My real issue is intake and smell. With the exhaust system described, what is the best method for creating an intake system that will not leak out smell? I feel cutting holes on the bottom may not cut it, but if somebody has done this, and it does work - please let me know. Any other suggestions are more than welcome.
Also - I need to be almost 100% silent with the fans. Any suggestions there? Also give me suggestions or tips on the exhaust system if you have any.
