OutGrow®'s 50/50 Mix
50% of our great horse manure based mushroom substrate and 50% golden wheat straw
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. OutGrow®'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.
OutGrow® 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. OutGrow®'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.
