As it says on the tin:
Look at the huge sclerotia pushing everything out of the jar.
Initially I was going to use these just for the sclerotia. Just for fun I threw a couple jars into the greenhouse to see what would happen.
After a month of no change these little thingies showed up, overnight.
The objective behind my recents posts (1, 2) is to encourage people to experiment and give 'exotic' and 'difficult' species a try, kind of like the beer brewing motto of RDWHAHB (Relax, don't worry, have a homebrew).
If one reads most threads and information online one could be led to believe that these species are almost impossible to grow. I was convinced that a plain vermiculite layer for mexicana would not work, and that caerulescens would need very special fruiting conditions, and that definitely they would be a lot harder than cubensis.
The following family picture shows them growing next to each other, in the same greenhouse, using almost the same teks. Not pictured are the different Pleurotus growing on the bottom shelf.
Remember, if it is not worth doing it wrong it is not worth doing at all.
Container: 160ml deli container, 5 cents USD each.
Substrate: Modified PF tek, replaced about 1/3 of the brown rice flour with hardwood sawdust (mainly oak), 60 minutes at 15 psi.
Casing: Just the dry vermiculite barrier from PF Tek.
Inoculum: Print -> Potato dextrose agar -> Syringe -> This jar.
Incubation: Neglected for 40 days in a dark cardboard box kept at 25 Celsius with a reptile heating cable and a thermostat. At this point the sclerotia exerted so much pressure that container caps started popping open, I harvested all but 2 jars.
Fruiting: After 40 day incubation placed in greenhouse that oscillates between 85% and 95% Rh, with very frequent air exchange and lots of natural light. Temperatures oscillate between 18 and 23 Celsius. The ones in the picture grew overnight after 4 weeks of no apparent change.
