Air Pump idea...need input...

Ok so I have seen the HEPA box for air pumps. Cool idea. I was wondering if a similar system would work...instead of the box and filter, just put the pump in a clean tyvek mailing envelope {maybe 2 envelopes?) and run the air tube as normal. Seal up the holes with duct tape or electrical/plastic tape after putting tube and cord in place. Hang off a nail or hook on a wall, as CO2 tends to be heavy and stays low. Anyone done/seen similar? Wonder if the tyvek would filter as well? Would it keep out as much bad stuff as a HEPA filter? I dont know but any input would be great!

For that type of an application I would use a new hepa vacuum bag as it will still filter efficiently but let a lot more air through then tyveck would. No chance of over heating of the pump that way. It works great .

I'm assuming you're using the air pump for you fruiting chamber? If so, you don't need to filter the air. It's not sterile anyways & as long as you don't have a plethora of mold all over your house, you'll be fine. I never filtered the air going into my blower for my GHs when I had them hooked up & it worked fine.
If you are going to filter it, use appropriate filter material, not tyvek. Just go to wally world or your local hardware store & buy a "hepa" air filter for your furnace & cut that to size.

Even if you don't =need= to keep the air in your FC sterile, it's still a great idea to keep it as clean as possible for a handful of reasons, the closer to sterile the better, IMHO. (<Begin list>1), if you want to make sterile spore-prints, having clean fruit in a clean-air environment is a great first step in ensuring sterility. (2) Same, of course, for cloning fruit. And I know you can clone really filthy, contaminate-ridden fruit, but why risk the waste of petri dishes and precious time cleaning up your cultures/spores when you could keep them clean to begin with? (3) When contaminate spores do get into your FC, and they =will= if it's exposed to open air, they will always have a chance at grabbing hold of some corner of vermiculite, some little bit of hay, a casing or whatever. If that never happens, cool, but it happens to people all the time. (4) Perlite can harbor contaminates. And it's cool if you never need to change or replace/sterilize the perlite in your FC. Mine almost always gets funny eventually, even in the clean air FC. So just as a time-saver/perlite-extender, filtered air is nice.(</list>)
Most of all, why would you want to expose your FC to all that crap when ya just don't have to? It took me 30 minutes and some scrounged parts to set up an automated HEPA filtered air setup.
Cleanliness is next to godliness, and what kinda fruit are we growing? The fruit of the gods.

(But for the record, I do have a plethora of mold in my house. More than that... it's awful. Stupid old building is a mold-farm.)

you dont need a sterile fruiting chamber.
or anything close to a sterile fruiting chamber.
people take clean spore prints daily from non-sterile fresh air-rich fruiting chamber.
and have zero problems with contams.

1 - no print is 100% sterile. That's damn near impossible.
2 - PE6 clone done in open air. I Ousted the air, opened the mono grabbed the pin then opened my jar & dropped that beast in.
3 - contaminates will ALWAYS be in your FC
4 - perlite comes sterile. After a while, it does get funky, but you just have to take it out & give a nice bleach water solution bath. Rinse well & put back in...or toss it, it's not that expensive & will still work in your garden.
I think your old moldy house is the problem, friend. IMHO

Because you get better yields if you do.

Interaction between surface bacteria and the mycelium is desirable.
Tyvek isn't going to allow enough airflow for an air pump. The pump will create a vacuum on the envelope, which will get probably sucked into the pump, further blocking airflow.

I like to keep things as clean as possible..nothing wrong with that.
I wouldnt put a pump in a tyvek envelope though, they dont allow for breathing..try putting it over your face and think if an air pump would do any better. The HEPA vacuum bag sounds like a good idea.

wow lots more input than i expected! thanks guys.
If you never hear from me again, its because i put a tyvek envelope over my head and it got stuck.....
