How to Use

• Apply the provided stick on filters over the vent holes
• Add your chosen substrate and mushroom spawn, mixing thoroughly
• Keep the monotub in a warm, dark spot and mist lightly to maintain humidity
• Monitor pinning and allow gas exchange through the vents
• Harvest your first flush within 3–4 weeks, with multiple flushes possible

Why Choose a Monotub?

• Higher yields than smaller grow kits or shotgun fruiting chambers
• Stick on filter patches provide precise air exchange and contamination control
• Less hands on maintenance compared to shotgun setups
• Supports a wide range of Gourmet Health Mushroom species at scale
• Compact, reusable, and simple to set up

Compared to shotgun chambers that require constant misting, a monotub retains
humidity better, reduces daily maintenance, and produces more reliable yields.
Ideal for gourmet species such as Oyster, Shiitake, and many more.
