    Product Details

    Simplified Monotub Setup

    This kit is designed to make it as easy as possible for you to start your first monotub grow. We've included everything you need - just add spores or liquid culture.

    Sterile, Reliable Components

    Grain and substrate are sterilized in a lab environment and packaged in filter patch bags for proper gas exchange. Just inoculate the grain bag with your spores or liquid culture, allow it to colonize, and then mix with substrate inside your tub.

    Designed for Bulk Fruiting

    Whether you’re growing in a closet, grow tent, or open-air room, this kit provides everything you need to grow high-yield flushes with species that thrive on coir-based, dung-style substrates.

    Usage

    Inoculate the grain bag with your spores or liquid culture via the injection port or in sterile conditions. Once colonized, sterilize all tub parts and liner with 70% isopropyl alcohol and mix the grain into the substrate inside your lined monotub. Apply the filters to your airflow holes and monitor conditions as your mushrooms fruit.
