hey guys, just bought a 4x4 spyder farmer. This is my first grow in a nice sized tent. The old lady said I could start growing a couple plants again, but her only stipulation is there has to be excellent odor control. My first couple grows, i just grew 5 plants out under a 600 watt hps in the corner of my basement and it started to reeeeeeeeek to high heaven during the last couple weeks of flower. I'm only planning on growing out two, possibly 3 plants in 5 gallon fabric pots. I'm growing all organic soil this time around. No liquid nutes, just the occasional compost tea. Whats the best fan and filter setup to ensure i don't have a pissed off baby mama on my hands???

This fan on 25-50% will be plenty.
You can get the fancy temperature/humidity controlled one for 40$ more

Amazon is out of stock of ac infinity filters but this is a good one.

My filter works best at slower speeds, be screwed without a variac. Theres a speed that no odour makes it through and its a lot lower than the filter rating.

Yes. Capability is always good, it is quieter at lower speeds and having more than you need allows you to plan for the 4x8 in 4 months

What is the 8" version rated cfm? I think the filter will pull it down a lot more than 30% no matter the make or model.

So is it bigger is better or lower is better as far as scrubbing and eliminating

Bigger will last longer and put less drag on your fan and i feel like the air moving through it slower will help remove more odor. A 6'' fan pulling air through a 6'' filter will probably see a 30% decrease in cfm where a 6'' fan pulling air through a 8'' filter might only see a 15-20% decrease in cfm.

Besides the actual an obvious attachment size what's the difference between the 6 inch filters and the 8-inch filters?

The physical size of the filter. 8 inch filters are bigger around and typically longer too. Ive done the math and they usually have about 2x as much carbon in them.
