So I've got these bags of colonized Ps. Mexicana var. Tampanensis, I was growing them out just for fun while I worked on my Brazilian and grow room processes.  This is a sclerotia forming variety, which I've never played with before.  

 

Should I fruit these or just leave as is for a few months and harvest the stones then?

That's up to you, man.  I would probably do both myself.  They are easy to fruit normally, and you can grow them like you would cubes or pans.  Very nice species.  I think you will like them.

I would do both as well. I have never grown any sclerotia producers before. I would be very interested in your experience with them. Good vibes.

just a few links from new vaults

As confirmed above by jammer and frog, as well as by the "Comprehensive Sclerotia" all-in-one Mex tek that is saved in the new vaults (stonesun 2011) sclerotia can be harvested at the same time as the spawn innoculates the final substrate. If you have a couple of bags, first I would use them slowly (one bag at a time) and i would experiment by spawning to multiple fruiting substrates and trying it with different amounts of stone harvesting.

Most pictures on here are shoebox-size or ziploc sandwixh type plastic trays, or mycobags. Those containers all suggest a thin depth is the way to go when you fruit. Either crumble and case withot expanding your mycelium, and fruit directly (simple) or expand to a suitable media and wait for colonization again (1 week, higher yield). Media could be pure coco coir or pure verm, very likely. Poo and straw in moderation.

Absolutely needs high fae on the entire fruiting surface, moisture shiuld be well controlled. Really calls for an automated system or a good shotgun terrarium in the right climate with ideally fanning throughout the day. There may be a strategy for pinning, such as a difference in temp between colonizing and fruiting conditions For that info consult Stamets.

You can use your bags to mag many times the number of bags, of course. Exponential growth has a way of netting massive yields. Fruit to larger casing trays if you do, or be ready to work overtime on prep and maintanance. According to Steampunk Scientist, mexicana has a clear preference for the unhulled millet grain, a component of most wbs mixes.

Shotgun terrariums for mexicana are not unheard of. I wonder if MlBjammer or anyone else can grow and mexicanas in sandbags? Properly ventilated and sized, and pasteurized....

A recipe I just read for these was like what for cubensis would be an all-out poo based fruitng substrate: poo/coir/straw/verm/gypsum. etc.

Btw apparently some isolates of the species, from back in the day, had trouble fruiting on the first few flushes. And dropping spores. (Workman 2006) waylitjim's post (2006) has some considerations of agar work, including sclerotia on agar and reviving/cleaning sclerotia for further agar work.
