The Inflatable Monotub Mushroom Grow Chamber – Boomer Shroomer makes it super easy to grow your own mushrooms at home. Whether you are just starting out or already have some experience, this clever and space-saving system gives you everything you need for successful growing.

Features

This patented inflatable monotub is designed for convenience, efficiency and top results. Thanks to its clever design, you don't need to drill, glue or assemble anything yourself. The transparent walls let you follow everything without disturbing, and the adjustable air filters ensure an optimal growing climate. Cleaning and storage are also a breeze. Just empty it and slide it into the cupboard.

What you need to get started

The Boomer Shroomer Inflatable Monotub works like a compact grow room, but to get the most out of it, you need a few essentials:

• Cleaning alcohol (70%) - For proper cleaning of the tub, your materials and yourself. Hygiene is crucial when growing.

• Fully colonised spawn - This is the basis for your cultivation. You can choose from different forms:

  • Grain bags already colonised with cubensis liquid culture, for example

  • A ready-to-use kit from Mondo, FreshMushrooms, all-In-One or Mystic Fungi

• Substrate mix - Recommended for growing cubensis. A ratio of 2 parts substrate to 1 part spawn works best.

Why this system is handy:

• No hassle with self-assembly: plug-and-play design

• Compact storage: only 10 cm thick when deflated

• Smart water management: with handy drainage hole at the bottom

• Good air circulation: with red plugs and white filters

• Transparent: follow the growing process without having to open it

• Less side growth: thanks to supplied inner lining

Ingredients and/or composition

The monotub is a complete, inflatable growing chamber with:

• Removable liner

• 10 red plugs (for the growth phase)

• 10 white air filters (for the harvest phase)

• Drainage hole at the bottom

Use

1. Preparing
   Inflate the tub (takes ±2 minutes). Clean your hands, arms and the inside and outside of the tub with 70% alcohol. Also treat the red plugs and place them in the openings.

2. Make mix
   Mix your fully colonised grain spawn with a moist substrate mix (test with a squeeze: 1-2 drops of water is perfect).

3. Fill
   Fill the tub with the mixture of spawn and substrate. Mix and press lightly to remove air bubbles.

4. Growth phase (7-14 days)
   Store at 21-24°C. Wait until the mycelium has taken over about 80% of the substrate.

5. Harvesting
   Replace the red plugs with the white filters. Ventilate for 10 seconds daily. Harvest when the membrane under the cap detaches.

6. Restart
   Add 1-2 litres of water, leave for 2 hours, drain and restart. Good for 3-5 harvests.
