Review: expanded to agar. very happy. - Look like these reviews cover multiple strains. I'm a commercial grower, I bought 5 strains, Chaga, Turkey, agarikon, Maitake, cordyceps, 4 are growing well on agar, the chaga looks damaged, myc is glassy and only the size of a dime after 2+weeks, the other 4 have overgrown the petri and are now in grain, doing well. Going to mix the syringe and try again with the chaga, not hopeful. The turkey tail is aggressive. Not bad for the price. Other reviews lack detail, lots of pitfalls, variables growing fungi, I'd recommend expanding on agar first, as opposed to directly into substrate, just to see what you're working with. contacted vendor, it seems chaga is a slow strain, they got right back and are sending a new culture in agar.
Review: colonization temp 40-50 F, fruiting temp 70 F - Its growing its growing, took almost a month and a half on pot pot sterilized 50/50 oak/soy in filtered mushroom bags at 45 degrees. It's doing it, its a mycelial colony. No special equipment, mush bags 50/50 pellet, a hot pot.. showered, washed my hands, wiped work down area with alcohol, spritzed alcohol every so often above me in a spray bottle on mist. Injected into sterilized self sealing injection ports on mush bags that had cooled overnight. used alcohol wipe to sterilize the syringe attachment port on the needle attached needle with a twist, wiped injection port, removed needle cover, injected the port, and refrigerated that easy.

### ⭐ Did not work…
*by T***S on November 10, 2023*

I carefully inoculated two sterile rye packets, following all guidelines. I got zero results. I advised the seller who sent me a petri dish showing mycelium growth. I guess that was to make me think the spores I received were live. I don’t think so.
