Grow Room Quiet Impressive (pun intended)

[puffer1958]

I am revising this post because after more research I determined that my eBay purchase of the 4Inch was insufficient for my needs so this is my current and hopefully final set up from AC Infinity. I am going with AC Infinity 6" fan with an amazing controller that works like a thermostat for the fan, raising or lowering the fan speed as temps fluctuate as in lights on/off etc. Anybody interested here is the eBay link.

AC Infinty is really impressive IMO and I think you might be impressed also. They are definitely marketing for our crowd but their product line is also very mainstream as in electronics cooling, HVAC vent boost, etc. In other words no cannabis leaves on their products,etc. They have an eBay presence and I believe the on eBay they offer free S&H whereas on their website S&H is extra $. The charcoal filters very expensive on eBay with free S&H but on their website their 6" filter delivered to your door is less than half what they are on eBay. It's almost like a typo it's so $$ on eBay. I think it's because on their website they are back-ordered until late Decemberish and they have they available now on eBay. Maybe, still crazy $$ on the bay. So, I am getting the fan/controller on eBay and the filter pre-ordered on their website. They are on Amazon also, though not as well represented IMO.
The fans are DC which gives them much quieter operation. It is designed for quiet stealth
This is their policy that I copied and pasted: FREE RETURNS
If you're not happy with your purchase for any reason, please contact us to receive a prepaid return label - Return shipping is absolutely FREE
That's hard to beat IMO
My little tent is a 3X3X6 secret jarden but it's very important to me to discretely provide for my girls that provide for my personal needs.

hey i'm a newbie. i'm in the process of building my 2'x3'x6' grow cabinet for a total CFM of 108. My question relates to the required minimum CFM regarding the carbon filter. Like you guys i plan on buying the ac infinity products to complete my project. Does the filter need to exceed the CFM's of the fan to properly deodorize and exhaust the air? do you have any thoughts or advise for me in regards that i am also planning a passive intake through my project as well? I plan on growing only 2-4 plants at a time and using it as a drying/curing chamber between grows also. thank you.

CFM of carbon filter must, at the very least, match the inline fan CFM. My filter CFM has always been higher than my inline fan CFM.

Ok. I plan on at least starting with a passive intake system to cut down on start up costs. I will however be making enough space to accommodate another fan and light trap too in case I elect to run an intake fan in the future. Thank you for your answer though it helped me out a lot
