Our Lifetime Guarantee

At Martian Mushrooms we pride ourselves in the quality of everything we sell. As the UK’s leading mushroom company, we go to great lengths to make sure we are giving everyone the best service possible.

We’re so confident about everything we have at Martian Mushrooms, that we fully guarantee our products for your entire lifetime!

Mushroom growing is not easy, and we know mistakes can happen. Our guarantee even applies to ALL of our grow bags, substrates and grains. So when things don’t go as planned, we’ve got you covered! We will replace anything for you free of charge.

🧫 Cultures or other growing products purchased elsewhere will invalidate this guarantee. This is because we cannot verify the quality or sterility of items not purchased from us.

🚫 Cultivation of prohibited species will void this guarantee.

🏽 Our LabPro Mushroom Laminar Flow Hoods are not covered by our lifetime guarantee, but they do come with a 2-year guarantee for quality assurance.
