Well, I think I've changed my mind... Again...

I have decided to up the cabinet dimensions to 28"x37"x65" tall. I'll use a 400 watt HID (switchable bulb), a 6" elicent inline fan and 6" ducting. I'll still be making my own carbon scrubber (6" inside, 8" outside, about 12-15" long) but will likely just buy a cool tube so that it fits into the 6" ducting without reducers.

The system will be:
DIY scrubber ----->6" cool tube---> 6" elicent inline----> possible DIY duct muffler-----> out of cabinet.

Total volume is about 40 cubic feet. I need at least 40x3=120 cfm to clear the air 3 times per minute. I think the 247 cfm elicent will be fine even with the resistance due to the scrubber and cool tube. What'ya think?

I have noticed that elicent makes two 6" fans, the 150A and the 150B. One is 247 CFM, one is 309 CFM... Now I just have to pick one... Any recommendations?

With information from this site, I was able to successfully complete a rubbermaid tub grow. So I have to THANK YOU ALL for this wealth of information. Now I am planning to build a second, slightly more classy cabinet. As a patient I have an easy supply of clones, so my plan is to start the clones in the rubbermaid, then move them in to the new cabinet for flowering when they are ready (somewhat Rating: 5
