So two things cause this, co2 and too much air flow. That yellowing is due to the lions drying out which can be made worse by the porous growth of lions in too high of a co2 environment where Swiss cheese like pockets form as opposed to a healthy looking fruit…so increase the CFMs of your exhaust (making sure your intake is low in co2 first) and this, with a co2 meter controller) should limit constant air flow which will cause drying of lions and increase what I call the ebb and flow system where fresh air is brought in as dirty co2 rich air is carried out in less frequent and quicker pulses. This also helps keep your humidity up in the winter time without taxing your humidification system. 

So every other sheet of corroplast goes straight from the top of the stack (return air) to the bottom of the stack for spore and co2 rich air dispersal…let’s call these the odd sheets…the even sheets have a blocker in them at the bottom and top of the stack and a shorter piece of Coroplast. Where air comes in from the side slots and up to the duct that feeds into the plenum or fruitroom. Because of the proximity to the intake and exhaust at the bottom of the stack of sheets it’s important to support the HRV up on a short wall of brick or cinder blocks of some kind with a pit of gravel (French drain) below. This way the intake (even) and the exhaust (odd) due to their necessary proximity, don’t intermingle. Does that make sense? Hard to out into words but I can certainly make a drawing…

We are currently using XLS-As that are essentially self supporting trays, I’ll make a post on here next week to show the converted slant shelf carts we made for cordy cultivation. Trays can help but if the bags on the shelves are left undisturbed through the dark colonization and light fruit formations they are unnecessary. We did just get some bins in from SacO2 which are interesting for cordy cultivation without the bag, I’ll post those up too come monday

Not currently, we are working towards more of a physical lab complex for the growing MycoWizards communities. The first one will be at the new Cap N Stem location in Lewiston Maine within a years time, acting as a launching pad and a welcome spot for any traveling MycoWizards members to work on projects, teach classes, etc!

Welcome! Whatchu got growing?!

Those beat pulp pellets are tough to break up eh? I remember using them years ago hoping the substrate would have a color effect on the fruitbodies!

Yea, its exactly as Brendan confirmed, a pretty common cultivation occurrence. Some phenotypes do it more than others and some genus are more inclined to perform this sort of selective growth as fruitbodies develop. I suspect it has a lot to do with which pathways produce faster growth for proper spore producing basidia for dispersion being the common goal. The old saying "cant save em all" likely sums it up.

What's your sub mix? Cook method? Strain used?

Sick!!! So Beech can be a real Biatch, but it just takes time. Incubation on MM takes between 4-6 weeks similar to p. adiposa in its maturation time. Fruiting is best initiated similar to AA-CNS, by top fruiting at 60-65F. While Beech really digs high humidity, it is susceptible to rosecomb like morphology so keeping a extremely finely atomized mist is preferred for proper fruitbody formations.

This is really radical stuff Phillipe, thanks so much for sharing the article with us. This sort of thing speaks to what we would love to see the mycowizards community and many more like it build in the form of community labs and collective farms, something much different than the insanity of the button industry's undoing in recent years.
