Yet another addition to our mushroom growing supplies!

Sterilized rye berries mushroom spawn.

We only use 100% certified organic rye berries for our spawn. Rye berries have been the choice grain spawn of mycologist for decades.
Known for their wonderful consistency and resistance to contamination, properly prepared rye berries are second-to-none for healthy mycelial growth. We fortify our rye berries by adding sulfur and calcium enhancing the performance of the rye berries as a substrate. In fact, they are so nutritious, you can just case the colonized grains or fruit right in the bag! Or you can do a bulk grow by doing a grain transfer to our other mushroom substrates. Please see our other items for casings, bulk substrates, and other great deals.

This sale is for a one pound (equal to 1 quart) bag of sterilized rye berries.

Great product. The grains always contain the right amount of water content and never have any popped kernels. Always sterilized to perfection. And Mike's customer service and shipping speed is impeccable. If you go anywhere else for your mycology needs you are just foolish.

I cannot recommend out-grow enough. My experience with them has been amazing. I ordered 4 of these bags, and somehow they got contaminated. I sent them and email and they quickly replied and sent me 4 new bags at no cost at all. Best constumer service ever and their products are superb. If I could give them 10 stars I would. Thanks guys you have a customer for life!!

Ordered it on the 16th of April and received it on April 20th. Paid only $15 for "First-Class Package International Service" into Canada. In all I am very impressed that my order was shipped the same day I ordered it. Will be inoculating my bag today, and will report back with results.
