Mushroom Substrate

This is the perfect mix of our compost and wheat straw. This mushroom substrate will produce great results for dung/straw loving fungi species. You will get much larger yields using this 50/50 mix compared to just casing grains or all-in-one grow bags. This product is sterilized and ready to use at your front door. Simply add your gourmet mushroom spawn to the 50/50 grow bag, reseal it, and mix. Out-Grow's straw/compost mix is one of the best mushroom growing substrates available on the internet. We use only natural and chemical free products to make our substrates.

Wheat StrawHorse ManureCoconut Coir vermiculite

Out-Grow uses field leached and shredded horse manure, shredded golden wheat straw, coconut coir, vermiculite and a couple other secret ingredients to produce a high quality mushroom substrate with a very nice, airy texture. Out-Grow's 50/50 mix will come heat sealed and sterilized in a mushroom grow bag for your convenience. You can grow right in the bag or add to trays or tubs to grow in.

I spawned 1 pint to 1lb of Out-Grow's 50/50 Manure/Straw Substrate. 1 week later, it was colonized. I didn't have everything setup yet, so the casing felt a little dry. I dunked the entire casing before first flush. Today, I'm in the middle of flush 5 and that was the only time I dunked. Performs fantastically! I will definitely use this product again! A+
