I'm asking because the plants will need either fresh air or CO2 (if you go with the sealed room), and because I have an idea for you. See if this makes sense: Keep everything like it is, but put a Y-duct splitter just before your fan. Then, you can attach a carbon filter to the open slot. That way, you can run fresh air through the cooltube AND suck out hot/stinky air from the growspace through the carbon filter. That way you solve a couple problems, and no smell. My fan is only 220 cfm and takes care of both my carbon filter exhaust and cooltube.

I see you ran out of money already ... but I was thinking the carbon filter would be the next thing on your shopping list, seems like you solved the ducting problem:jointsmile:
yo bigtops, yeah i have another rvk100a running with a carbon filter in the room to circulate air plus a rotating fan but i really like your idea about the y splitter heh it makes sense I'll give it a go, gotta find one first though heehehe.. thanks man that really helps :jointsmile:


I will let you know how i get on

Peace,
