thanks for the reply, and I think thats what i'm going to do, build some sort of box

This is what i'm thinking, building a 4'x4'x7' box sealed with silicone + screws, covering the inside of the box with penguin paper, put an exhaust fan at the top pushing the air through a carbon scrubber and adding a passive intake hole about 4"-6" round very close to the bottom for fresh air, sound alright?

just wondering about a few things, can I use just about any type of wood? I want to spend the least I have to, but if needed, i'll spend the money. I was thinking about using around 180-190 CFM exhaust fan(has to be powerful enough to run through the scrubber) does this sound efficient? and should I use an intake fan or should the hole be enough? Anything else anyone can recommend me doing? thanks in advance for replies, i appreciate it:thumbsup:
