White cotton ball on top of Pearl Oyster casing?
    #28186651 - 02/14/23 03:30 AM (1 year, 10 months ago)



These Pearl Oysters have been fruiting for about 4 days - I noticed that they seemed tight on space because of the bag, so I started cutting the bag vertically and found this big white fuzz ball on top of the casing. Should I hit it with hydrogen peroxide or physically remove it, or leave it be? Or something else? Thank you!

don't worry about it, it's just myc
never grown pearl oyster but these look very stringy for an oyster and need more FAE
where are you fruiting them?

also you might get more answers on the gormets board https://www.shroomery.org/forums/postlist.php/Board/13

Awesome thank you! Glad I didn't jump to the wrong conclusion. These are being fruited in an unmodified tub with an ultrasonic humidified piped in, set to start at 85% rH and stop at 89%rH. Oh, and some rainbow LEDs for a bit of supplemental light. Originally I had them placed in a SFC and as I understand it, top lighting is part of what helps regulate the humidity in the tote in an SFC.

you are going to have problems getting enough fresh air there
how is the weather around you?

Southern California so relatively dry... The dual requirements for high humidity and lots of FAE is a bit challenging imo. The first time I grew Pink Oysters I cut a hole in the side of a block and had a humidifier pointed directly at it, which worked pretty well. But it was really inefficient using a a humidifier to grow only one block so this time I tried loading up a tub, but from other threads here I suspect Oysters grow much better from a vertical slit rather than horizontal like how I've placed them.

I'm also trying to see if I can grow these outdoors -- I'm hoping mister nozzles inside an outdoor 'martha tent' of sorts will provide enough air exchange and humidity to keep oysters alive.

When I was looking up how to build a SFC, I found an old quote by RR on the subject:

"The holes in the bottom increase humidity. How? It's a development from something I learned working on the Alaska Pipeline project in the 1970's, helping to engineer the supports that are actually self contained refrigeration units that keep the tundra frozen even in summer so they don't shift, thus preventing the pipeline from rupturing. The supports require no electricity to operate.
The methodology is this: Air currents travel from high pressure to low. Heat expands the air, thus causing low pressure. Cold compresses the air, thus causing high pressure. The damp perlite is cold, so the air surrounding the perlite is our 'high' pressure. The substrates within a terrarium produce heat, as does the lights shining through the sides or top, thus the air in upper terrarium becomes 'low' pressure. This causes air to want to flow through the perlite and into the terrarium, but only if there is an entry point at the bottom for the air to be drawn in. The air, by natural convection passes through the perlite, absorbing moisture as it does. It then enters the terrarium, and is expelled through the holes above. This natural circulation provides FAE without fanning, while keeping the humidity higher than it would otherwise be.


*The fruiting chamber I designed has holes in all six sides. This results in convection and circulation. It is NOT a still air environment! The mushroom substrates produce heat, and also the lighting that shines through the fruiting chamber produces heat. These two produce convection. Perhaps if you'd read posts before jumping into shit you know nothing of, you'd have seen that. Sorry, but this pisses me off. Don't attack my work because you don't understand the science behind it. Now, in a so-called 'shotgun' fruiting chamber with holes on all six sides, would you suppose the CO2 drains out the bottom? It doesn't. It mixes with the air. I see absolutely NO change in CO2 concentration from the top to the bottom of the fruiting chamber. CO2 levels are higher than ambient in the room, but lower than they would be in a 'still air' terrarium, as if anyone who has knowledge of the life cycle of fungi would ever make such a thing"

I may have misunderstood the importance of the lighting, but after I set up my SFC initially, I measured the temp of the blocks and noticed that they didn't really create much heat so I assumed that lighting was contributing more to the heat required for convection.

Thanks, you are totally right. I originally had the plastic bag a few inches above the substrate level and found that the stems stretched upwards as if they were enokis. I just harvested and cut the plastic so hopefully this time they will not be growing in concentrated Co2 >.<
