12qt Shoebox Refill Kit | Mushroom Substrate and Grain
B.P.

the grain: i picked milo took off nicely, 2 cc’s per bag, 5 bags per syringe. Works very nice, bags will be done withing a week. I should break and shake right now but, I think ill wait another week or so. As for the bulk substrate, looks great ive been keeping it in our storage room, its super chilly in there. And, it should work great when the time comes. Personally, ive never had issues with any of the bags ive purchased. I hardly inoc in my SAB anymore, as theres no need I just flame sterilize the needle, and inoculate.
