Pre-Pasteurized Casing Mix

Starting at: $5.95

Please Choose:

Pre-pasteurized mushroom casing mixture in a gusseted autoclave bag with filter patch. Specifically formulated for mushroom cultivation, this product is to be used in conjunction with our pre-pasteurized mushroom compost. The Shroom Supply casing mix is a non-nutritious blend of four choice ingredients: organic peat moss, coarse vermiculite, hydrated lime (for pH adjustment), and organic powdered gypsum (supplementing the mix with calcium and sulfur—essential elements for fruit body formation).

Although a casing layer is not required for the cultivation of most mushroom strains (unless fruiting directly from colonized grain, in which case, it is required), it can be beneficial to the life-cycle of bulk substrates. A casing layer provides mushroom mycelium with an optimal micro-climate which promotes pinning and also serves as a contamination barrier to the cased substrate. These combined effects promote the longevity of the substrate which can lead to additional flushes and higher yields.

The casing mixture should be applied in a thin layer to the top of a block of fully colonized bulk substrate, like our pre-pasteurized mushroom compost.

Shroom Supply casing mixture comes pre-pasteurized at an optimal moisture level, making it ready to use right out of the bag. All casing material is adjusted to the ideal pH of 7.5 before it is shipped. This product comes heat-sealed in sterile, filter-patch mycobags and can be stored at room temperature for up to 21 days. If more time is needed, it can be stored in the freezer and dethawed before use. All casing orders over 1 lb. come separated in 5 lb. bags.

Made to order, usually ships within 2 business days.

What can be said that has Not Already been professed about this company and there attention to EVERY DETAIL. This compost has NEVER let me down.. ALWAYS arrives Completely STERILE and the automatic and accelerated growth is seen taking hold in under 24hrs of combining with spawn. Not to mention it has dramatically increased BOTH mushroom size and harvests. Has all the nutrition your mycellium projects require from first flush to the last. Very professional personnel with amazing tech support and Very Quick Responses should anything arise. The ONLY company I will EVER purchase from. Mush Love and THANKS for everything Fam Ash

Fastest shipping on the market that I've ever come across, and the casing mix has exceeded my expectations. No one can top this product in any way in my opinion! MushLove for the shroom supply. Entirely worth the modest price!

The only way shipping could get faster is if you were psychic! Everything is blended and hydrated perfectly. You almost make it too easy. And I appreciate the fair prices, low shipping rates and the fact that you don't over package. Also, you answer all my questions.
