Get the 1 gallon pail of ona gel-----------------get a cheap fan that you can duck tape to the top-----------drill the holes and turn it on------you can do this project under the budget you have----50.00---I think you will be surprised.

Suggest mayb close off corner of room, closet, something, to keep smell to minimum, that way its easier controlled.

hmm... didnt know that rule of thumb but i had assumed that you would probably want the air turned over in a pretty short amount of time, so i was a little surprised with the 170 cfm. that is the only room that i have available right now and boxing out a section of it wont be possible at the moment, i am actually setting up a cab about 2x4x5 but it wont be ready till my next grow. i may just have to breakdown and go ahead and just buy a fan/filter combo and maybe supplement it as best as possible with ONA.
