Get to know us by using one of our cultures produced in-house - build your genetic library & trial our strains made here at Redwood Mushroom Supply.

What gives? All we ask is that you follow us on Instagram or Facebook, and sign up for our email list using the form below. Once you do that, you'll receive a code for $20 off a single culture from our liquid culture bank. Limit 1 per user.

Shipping and Handling: In order to help us get the culture to you, we ask that you pay shipping and handling - your discount code covers the cost of your first culture, but we ask that you meet us in the middle on shipping so we can continue to help grow the mycology hobby with this program.
