and the back-pressure caused by the filter wont burn out the motor?




Polyfill is often used in aquaria (to filter water actually) but doesnt seem to burn out pump engines.


Yeah, as long as you don't pack it ultra tight, it won't unless your pump is ultra-cheap.




LOl my pump IS ultra cheap (6$ and 240 liters an hour max). It was an bargain, normal price wasnt that high either I believe about 20$.
But untill now I wasnt planning on filtering my air. And arent contams more likely to affect incubated jars more then colonized cakes/casings in the pmp/fruiting chamber?


Yes, but you can never be too clean. Why make your mycelium waste energy fighting off contams if you can avoid it?

I guess it just depends on the pump. But a polyfill air filter shouldn't add much resistance unless it is improperly packed. I do know that significant resistance can cause them to die rapidly in some cases, though.

I think that using a HEPA vacuum cleaner bag is probably the coolest idea if you want to be hardcore. There's no way that polyfill could even come close to that kind of filtration, but I'm sure it's more than adequate for most.

I'm setting up my terrarium tomorrow. A 30gal tub with perlite and 1 8" air stone with pump. I'll also be using a home made polyfil filter on it. I have 6 cakes getting ready. 1 is ready to be dunked tonight and rolled tomorrow. The rest will be ready soon. I'm excited. First grow for me.

Any local indoor gardening shop should have it.

Open up the phone book and start calling around.

Couldn't you just put the air pump in the middle of a big box of polyfill? (Or is heat a problem?)

I used to have an air pump called a "Silent Giant". It was a heavy monster. When if finally died I did a post mortem. Inside was a tiny little stinker of a pump packed in lots of fine gravel.

For the air pump(s), couldn't you take say a 5-12 quart container, drill 2 holes, one for the electrical cords and one for the tubs, seal put the pumps into the container run the cords out the larger hole, the tubes out the other, then seal both holes with Stuffit, or some other sealing material, silicone, epoxy, etc.  Then, cover the entire top of the container with a single layer of Tyvek.  Given the very large surface area of the tyvek, would it be large enough to allow enough air flow for the pumps in the container, say 2 or 3 pumps?  You could seal the tyvek onto the top of the container by wrapping the tyvek over the edges and gluing the edges of the tyvek to the upper edges of the container with epoxy/silicone.  Would this work?
