So I'm gearing up for my first indoor grow. I've got my lumber and drywall and as soon as I knock out a couple more projects around the house I'm clear to build. My grow room will be 5'W x 6'L x 7'H (210 csf) although my actual grow area will be smaller with 6 - 8 plants in a scrog setup. I've been busy accumulating knowledge and have found these boards to be full of wizards and grow-geeks, all very willing to help. In my situation, odor is the number one concern. It is a basement grow in a house that I own. Everything very secure but I have venting issues. There is no way to vent externally so I will be scrubbing and venting into an adjacent room. In-laws, cleaning lady, and guests are my biggest concern. This needs to be bullet proof and I don't mind spending a little dosh to get it right. After reading through the tutorials and other stickies here, I was set to go with a 6" inline fan coupled with a carbon scrubber plus an ozonator for redundancy. However, I am wondering if I should just pop for an inline ozone generator. The carbon filter is going to set me back ~$100 to start and then $100 / year for replacements. The 1000 csf ozonator is ~$200 to start. I can get a 6" inline ozone light for $350 which needs replacement bulbs every 2 years at $120. So the inline ozone solution is a bit more to start but less to run year over year. Like I said, cost isn't the determining factor. My question is, which solution will provide the most reliable, fail proof odor control? Are they similar? Does anyone have experience with the inline ozone controllers? Would someone using a carbon scrubber please comment on their effectiveness? General feedback much appreciated.
