Don't forget to clean your exhaust fan!
    #14595385 - 06/11/11 10:53 AM (12 years, 8 months ago)

For the past month or so I have been wondering why my pasteurized straw logs were going foul while colonizing in my basement (I use basement for fruiting area as well).  I have a nice hydrofarm inline 440cfm fan that I have been using for the past year.  I had never cleaned it, it never 'looked' dirty, but of course the fan blades are on the inside so unless you stop the fan (which I never did to check) and open it up you never know.

So I took it apart and cleaned it out with hot water and a rag.  There was 1/4 of spores/dust caked up over every internal part.  Needless to say now it is running twice as hard.  I feel pretty stupid/careless for not checking sooner.  Now you can learn from my mistake.

Is there a way to rig up a filtration system for the fan?

I give you a year at most and you'll never be able to grow oysters indoors again, if that's what clogged up the blower.  Watch for headache, coughing, fever, and general flu symptoms.  That's how you'll know it's oyster spore allergy setting in.

Its a combination of sticky spores and dust.  I don't let my oysters mature to the point of heavy spore load so I am not worried.  I have no allergies and I played outside when I was a kid, and took showers in a nasty black mold infested basement.  I'm pretty resiliant to dust and spores, unlike some city folk.

Me too.  All that went out the window a few years after I started growing oysters.  I have no other allergies.  Zero.

Is this an oyster-specific problem because of the massive spore load of oysters?  Or will sensitization happen with any mushroom if you work with it enough?  Do you have any problems with allergies from indoor shiitake cultivation, for instance?

Nope, just oyster mushrooms.  The spores are toxic as hell.  In OK and TX I used to hide my garden in ragweed patches and never got allergy, even though nearly everyone gets ragweed pollen allergy.  To this day, the mold spore and tree pollen, etc., can be sky high and I'm fine, but the Mrs brought in a small basket of oyster mushrooms she picked by the creek to cook for dinner, and within minutes I had a fever, hacking in my chest and headache from hell.  I didn't even know she had brought them in until she said she knew why I was sick.  An hour later I was fine.

It takes a few years to develop, so if you're growing oyster mushrooms, always wear a respirator before problems start, to forestall the onset.

Jeez, that sounds nasty as hell.  Would you like some dengue fever symptoms with those oysters sir? 

That's some good advice, thanks RR.

Well I've been growing bulk oysters for the past 3 years with no respiratory problems, and the first year I let them mature far longer.  I would have to say it is person specific.  I think you were just made to grow other mushrooms RR, doesn't Mrs. Rabbit expose herself to oysters often too?

BTW, now that my fans are clean I have a HUGE improvement in cap formation, etc.. in my basement.  Things just slowly degraded such that I never could pinpoint the problem till now.

Glad ya got it worked out.

I became allergic to the spores when I had a mini-greenhouse in my bedroom, so I was sleeping for several hours a day in there.  If I had always just entered when necessary, I probably wouldn't have developed the toxicity to them.

I still like to eat them, but they have to grow outdoors.  Of course, they do better outside and form much better and meatier fruits out along the creek anyway.  I've got some remnants of straw logs from three summers ago that are still producing.  I'd never be able to keep a straw log indoors for three years without it turning green.

How do you keep slugs, earwigs and millipedes off your outdoor fruits?  When I put some spent blogs/bags out to do follow up flushes the local wildlife get to them well before I do.

I'd like to hear this question answered, too.

I don't have to.  They don't exist in this harsh climate.  The only insect that gets on my mushrooms is some tiny spore-eating insect, which drops right off when I thump the cap.  They only eat the spores and don't damage the product.

Slugs don't like to crawl over copper. If the earwigs and millipedes are consuming the fruits, you might need to make a screened in area.
