  • Our take on the Grow Kit Mushroom Grow Kit

    This is a mushroom growing kit built around standard 1020 trays: a deep mesh tray, a deep solid tray, a humidity dome with adjustable vents, a blackout dome and a coco coir brick. The blackout dome lets you colonize substrate in a lit room, and the vented humidity dome controls moisture for fruiting. Spawn is not included, so you supply your own culture or inoculated grain. It suits beginners who want a reusable tray-and-dome setup rather than a one-shot grow bag, and it fits monotubs and Martha tents.

    Questions and answers

    Do I need to buy mushroom spawn separately?
    Yes. The kit ships with trays, domes and a coco coir brick, but no spawn or culture. You add your own grain spawn or inoculated substrate.
    What mushrooms can I grow in this kit?
    It works best with species that fruit in trays and tolerate high humidity, such as oyster and lion's mane. Coco coir alone suits oyster mushrooms; wood-loving species need wood chips or sawdust added.
    How does the blackout dome work?
    It covers the tray and blocks light so the substrate can colonize in a normally lit room. Once the block is fully colonized, you swap it for the vented humidity dome to trigger fruiting.
    How do I control humidity and fresh air?
    The humidity dome has adjustable vents. Open them wider for more fresh air and lower humidity, close them to hold moisture. You still need to mist and check the block daily.
    Can I use this kit inside a Martha tent or monotub?
    Yes. The 1020 trays fit standard Martha tent shelving and monotub setups. The domes are optional once the block is inside a larger fruiting chamber.
    How should I store the kit before use?
    Keep the coco coir brick dry until you are ready to pasteurize it. The trays and domes store flat and stack; refrigeration applies to the coir once it is hydrated.
