The Monotub Mushroom Grow Kit allows you to start your first monotub grow with ease. This bundle includes an official Boomer Shroomer inflatable monotub, a 2kg sterile CVG bag, and your choice of 1kg sterile grain bag. This creates an optimal 1:2 grain-to-sub ratio inside your monotub, which is ideal for growing exotic mushrooms. An isopropyl wipe is included with each bag to help you with the inoculation process, but you can also add an aseptic technique kit for best results. 

You’ll need to purchase your own spores or liquid culture to start using this monotub grow kit. But don’t worry about contamination! Our grain and substrate bags are included in our 100% sterile guarantee. Looking to replenish your used monotub instead?

Storage Instructions

All sterile bags should be removed from any delivery packaging immediately after being received. This allows the filter patch to breathe, which prevents moisture from passing through the filter and drawing contaminants into the bag.

We recommend storing the bags upright, in a cool, dark place like a cupboard, for up to 7 days to observe that the bag is sterile before use. Do not store in the fridge. All bags can be stored for up to 6 weeks, but should be used as soon as possible. Our sterile bags are covered by our sterile guarantee, so in the unlikely event that your unused bag contaminates within 30 days of receiving it, please contact us for a replacement.
