Description

This is a bulk option for purchasing 5x5lb bags of our coco coir and vermiculite substrate. This is a discount pack compared to purchasing 5 5lb bags individually.

Our proprietary substrate mix! Crafted through years of experience providing great results consistently. Tired of reading all the websites telling you to add this that or the other thing? Forget it, we’ve worked through all that ourselves and figured out what works best!

Our substrate is a mix of high quality organic coconut coir, two grades of vermiculite to ensure aeration, gypsum, and Azomite to provide mineral content for your mushrooms. We’ve worked for years to perfect this mixture and have landed on a recipe sure to give you large abundant flushes every grow. Perfect for all dung and manure loving mushrooms! Please note, this is plain substrate and does require grain spawn to achieve colonization, inoculating this material with spores or liquid culture will not grow mycelium, or will grow extremely weak or slow growing mycelium.

This product is sterilized and ready to use. Just mix with your colonized spawn and you’re ready to go! 5lbs is enough substrate mix to top dress multiple bags of spawn or to create 1 monotub when mixed with 5lbs or 3lbs of spawn in a medium to large container; feel free to message us to confirm which size for what size tub.

Heat sealed, preventing contaminants.
