Our 2kg bulk substrate bags are a special blend of coconut coir and soybean hulls, designed to give maximum yields. The substrate is sterilised at 15psi and then sealed in our HEPA-filtered laboratory, ready for you to inoculate at home.

Our products are more than just a purchase - they're a guarantee! Yes, we promise your substrate will arrive free of any contaminants, or we'll send you a replacement.

Don't wait! With all orders shipped the next business day, your mushroom adventure can start ASAP.
