Bulk Mushroom Substrate
About Our Magic Substrate for Monotubs
Our proprietary mushroom substrate blend, sized for a monotub, pre-hydrated to field capacity and ready to spawn straight out of the bag. Built for growers running at scale.
What it is
The same proprietary blend, sized for a monotub. It is pre-hydrated to field capacity, so it is ready to spawn directly out of the bag without adjusting the moisture yourself.
What it is for
This is our heaviest-hitting substrate, built for growers running at scale, in large monotubs or outdoor beds.
How to use it
Use it as a bulk substrate on its own, or layer it with grain spawn. Moisture is already dialed to field capacity, so it is ready to go straight from the bag.
Shipping and pickup
Ships nationwide from our San Diego farm, with free shipping on orders of $50 or more. Free local pickup in El Cajon is available at checkout.
