These are professionally isolated strains to produce consistently high yields and contamination resistance. The same commercial cultures we use to cultivate our own mushrooms – Many companies don’t sell their master cultures, but we do. We’re in the market for promoting mushroom cultivation, and we think you deserve the best. Beware of inferior cultures and strains sold by other companies.

Produced in our dedicated lab, we offer 100% Clean and Viable Cultures, Guaranteed or your money back.

We recommended taking multiple agar wedges and slants to backup the strain.

All cultures are supplied in either glass culture tube or plastic petri dishes, each double sealed with Parafilm laboratory film to ensure contamination resistance and breathability of all cultures.

If possible, store cultures in a Styrofoam container to stop temperature fluctuations within the culture plate which can cause condensation and lead to potential contamination.

All cultures are made to order, so please allow 2 weeks to fulfil order.

Please review the drop-down sections below before placing your order, especially product lead-times if stated.

Our shipping couriers may leave parcels with a neighbor or in a safe place if no one is home to receive them. To prevent this, please select the designated signed-for service at checkout and ensure you are available to receive the parcel. Otherwise, the package will be held at your local sorting office or returned to us.

  1. Kevin –

    £70 for a commercial isolated mushroom strain? …with insurance. Total bargain! Have wanted to use an isolate for years so I can do accurate A/B tests to improve my skills. Will update review after harvests to report back on yields and performance. Thanks, Kevin
