Help with 2 Questions about fans & DYI Carbon scubber

[phatpharmer]

Hi guy's to the first question right away I'm investing in some proper fans and was wondering what size I'll need. The demensions of the room are 10ftLx10ftWx8ftH, I use half to veg and half to flower I also will be using a DYI carbon scrubber for the smell I also use a 1000wMH for flower and 3 double tube T8 floros (6x28w bulbs) for my veg .Right now I'm using just normal house hold fans (like 6 of them) so the noise sounds like a small aircraft plus at times it can be hard to handle heat . The fans I'm looking at are the Vortex 6" 449 cfm or the 8" 747 cfm fan I'll be buying 2 one for intake one for exhaust, the price difference is about 100$ so if I can I would like to get the smaller cheaper one but if needed I will fork out the extra $$ for the girls:hubba: or should I even go bigger! Now to the second question I'm making my own DYI carbon Scubber following the direction on this forum the question I have can I get away with an 8" scubber like the one thats on the forum or should I make a bigger one. I can get the parts to make a 12" scubber but I'm not sure if I'll need to make one that big actually I probally can get the parts to make 14" scubber but like I said I'm not sure what size I should build. Well those are my 2 questions any and all help appreciated as I'm going to be working on these projects this weekend!thanks again PP:hubba:

If your got two 5ftx5ftx8ft rooms thats 200 cubic foot per room. you will want to change the air in those rooms around 3 times a minute, so buy both fans and put the smaller 449 cfm fan with no scrubber in the veg room, and the bigger 747 cfm fan with your diy scrubber in the bud room, also i would make the 8" carbon scrubber but just make it longer. If heat is an issue cut some holes for passive air intakes you dont need fans on the intake..
Hope thats helps ya phat.
