Well I used the diy that Bodom posted .. http://boards.cannabis.com/growroom-...ml#post1075003

I have to make one more then I will have completely figured out the exhaust smell issues with my grow cab. I have one already on the main cab exhaust and since I have taken one tube off my light hood to help with temps in box I have to add a filter to that as well otherwise I would say that its works pretty good. If I was going to make another one of this size I would make it longer to spread the air flow over a larger space and to not create as much back pressure of my inline duct fan. It was rated at 250cfm which is fine for this size. I will soon invest in a eco plus brand or something similar in quality, as well as a pro made carbon scrubber.

The money I have spent would be better suited if I went first class all the way instead of half ass so gradually I will upgrade everything once things are dialed in, like grow three or so. The largest cost was the light/hood/ballast which ran about 360-$420 and then the box creation. Its funny how little things add up I would have to say I have spent almost 1k or so to date. Its worth it though and wouldn't have it any other way..

Also I really wish my digi had a macro function so I could zoom in and share what I think is my preflower that I so desperately wish to see. They are not definitive just yet but should be in a few days..
