    🏠 Monotub Starter Kit — Everything You Need to Build Your Grow Chamber

    The Monotub Starter Kit gives you the hardware to create the perfect fruiting environment for your mushroom grows. A properly built monotub maintains humidity, provides fresh air exchange, and gives your substrate the space it needs to produce flush after flush. Whether you're upgrading from a shoebox grow or starting your first serious cultivation project, this kit takes the guesswork out of building a fruiting chamber.

    What's Included

    • Monotub with appropriate modifications (as listed on product detail page)
    • Substrate and/or grain where applicable
    • Basic workflow and care instructions

    How to Use

    • Assemble the monotub with provided components per included instructions.
    • Add your colonized substrate to the tub and level the surface.
    • Maintain humidity (85-95%) and provide fresh air exchange via the tub's filtered holes.
    • Mist and fan as needed, then harvest when mushrooms reach maturity.

    Storage & Care

    Store in a clean, dry place at room temperature. Clean and sanitize between grows to prevent contamination buildup. Tub components are reusable across multiple grow cycles.

    Quality

    Each kit is assembled with durable, grow-tested components. Instructions are included to get you from unboxing to fruiting conditions quickly.

    Difficulty

    Beginner — ideal for first-time monotub projects.

    How to Use This Growing Enclosure

    1. Drill holes in the sides of the tub according to your fruiting chamber design (if not pre-drilled).
    2. Fill with colonized substrate — break up your colonized grain/substrate mix and pack it into the tub.
    3. Mist daily to maintain humidity at 80-90%.
    4. Fan the tub 2-3 times daily for fresh air exchange.
    5. Harvest when caps open — pick before the veil breaks for best quality.

    Tip: A monotub is one of the most reliable and cost-effective fruiting chamber designs. Polyfill or micropore tape over the holes provides filtered air exchange while maintaining humidity.

    What's in the Box

    • 1x monotub container with lid
    • Drill bit set (if applicable)

    Shipping & Storage

    All orders ship within 1-2 business days from our Colorado facility. Liquid cultures ship in insulated packaging to maintain viability. Store LC syringes in the refrigerator (35-45°F) until use. Grain spawn and substrate bags should be used within 2 weeks of delivery for best results. Ready-to-fruit blocks can be stored at room temperature for up to 2 weeks.

    Our Clean-or-Replace Guarantee

    Every liquid culture is test-inoculated on agar before release to verify purity and viability. If your culture arrives contaminated or fails to colonize, contact us within 14 days with a photo and we'll send a free replacement. No return required.

    New to Mushroom Growing?

    If this is your first grow, we recommend starting with a All-in-One Grow Bag or a Ready-to-Fruit Block — both are designed for beginners and require minimal equipment. For liquid culture use, you'll also need a grain spawn bag and a substrate bag. Check out our growing guides for step-by-step instructions.
