I am able to offer both manure & sawdust based substrates in 5lb bags, accommodating needs for growers seeking to work with either wood loving mushrooms (lignophiles) like pleurotus (oysters), lentinula (shiitake) or hericium (Lion’s Mane) and also for dung loving mushrooms (corporphiles) like agaricus blazei, agaricus bisporus or other cultivated species of dung loving mushrooms.

For custom blends or bulk orders (10 bags+), please contact

Supplementation is @ 20% unless you indicate in the notes otherwise. Sawdust is supplemented at rates suited for most mushrooms aside from Shiitake, if you’re looking for sawdust substrates for shiitake PLEASE INDICATE IN THE NOTES! Otherwise you will have mutated fruits!

Shipping is in flat rate boxes only. If you order alongside other items these will ship separately.

This keeps costs lower (free boxes & supplies) as 5lb boxes (up to 20lbs can go in a large flat rate) are heavy to ship, doubly so when you order more.

Hardwood substrates are cooked 2x/mo, please email me if you’re curious on the current lead time.
