Block looks very healthy except for some stains from the grain and compost on the plastic, should I or can I attempt to fruit this as a block in a fruiting chamber? I haven't had good luck with bulk grows and I'm out of mushrooms so I'm looking for the safest most promising way to restock without losing to contamination. Any advice appreciated. Strain is B , started in May.

Bag is rye with my own amended compost with cow manure compost/wood fines/food waste digestrate compost amended with gypsum, vermiculite, and coir (yes I know the lignin is not digested by cube sis, it's for moisture control and compost that's available).

Anyway, any advice appreciated.
