Collection: Monotub Mushroom Grow Kits & Monotub Refills

These products are designed for both monotub and BagTek ‘fruit in the bag’ style cultivation. Choose from a complete monotub mushroom grow kit (monotub, a sterile grain bag and sterilised bulk substrate), or keep it simple with a bag combo that can be used for refilling your monotub, or BagTek growing. These kits are much more cost effective than buying separately. Plus, they’re available with next-day UK delivery as standard.

Monotub Mushroom Grow Kit & Refill Bundles FAQ:

What is a monotub grow kit?

A monotub grow kit includes a monotub fruiting chamber, and a pre-measured bundle of sterile grain and substrate – designed specifically to be used for monotub mushroom cultivation. Monotub refill kits provide the fresh supplies (sterile grain and sub) you need to reuse your existing monotub.

What is BagTek?

BagTek is a mushroom cultivation method where sterile grain is colonised and mixed directly with the substrate inside the substrate bag for further colonisation. Growers using the BagTek method then either fruit directly inside the bag or place the bag into a designated fruiting chamber.

How do I choose the right bundle size for my monotub?

The correct monotub refill size to choose depends on the volume of your tub and the desired substrate/grain depth. For the most accurate choice, try our Spawn & Substrate Monotub Calculator.

Can I use these bundles with any mushroom species?

Our bundles are designed to work with most cultivable species of mushrooms. Our grain & CVG bundles are better suited for gourmet and exotic mushrooms, but if you are growing gourmet or functional mushrooms instead, you may want to use our Master Mix as substrate.

What’s the difference between a monotub grow kit and an all-in-one grow bag?

A monotub grow kit is a multi-bag bundle (grain bag + substrate bag) designed for fruiting in the provided monotub, while all-in-one grow bags combine everything into a single bag for standalone use (no grain to substrate transfer necessary).

How quickly are monotub kits shipped?

All of our monotub grow kits and refill bundles are prepared fresh and sterilised before dispatch. Most in-stock UK orders placed before our cutoff ship the same day via the DPD next-day delivery service.
