I've had several questions concerning how my carbon filter is tied into the inline fan. Unlike most grow cabs, my fan and carbon filter as well as ballast are located in the crawlspace under the house. Due to space constraints (anyone who has seen my cab knows what I mean by "space constraints"), and that I needed to utilize every square inch of the area of the grow cab for just that-growing. I'm lucky to have gotten the wife to sacrifice the space I've acquired. As far as UNDER the house, well, I don't think we'll ever have to worry about "violating her space" under the house, so I determined to locate whatever I could there, including fans, filters and ballast. These alone, would have COMPLETELY eaten up my clone/veg area. The reason for this project was to up the cfm from the 170 cfm turbine fan. To do this, I opted for the next step up, a 6", 440 cfm turbine fan. It will be enclosed just like it's little brother before it was. In addition, as well as before, soundproofing has been incorporated into the design. I have a client who has some leftover eggcrate foam he used for soundproofing his at home recording studio, and has given me permission to use whatever I need, which won't be much to line the INSIDE of the 30 gallon tub. Maybe this weekend I'll complete the project. Here's where I'm at. Enjoy.
Even with the R-13 exterior insulation, I CAN'T wait to glue the eggcrate foam to the interior of the tub. Also, all the pipe, including the 4"PVC leading through the floor has received an insulated wrap as well. With the extra cfm, (even though I've had to reduce the fan inlet and outlet) should not only function hands down better than the 170 cfm unit, it should enable me to finally utilize the fan reostat (5 amp ceiling fan control) located in the grow cab and not have to run the fan at full bore 100% anymore.
So, I think this little project is about complete, and should take care of the last of my heat related cabinet issues, and now do so without breaking a sweat. It will also give me a chance to see just HOW well the 2nd revision carbon filter flows.
