Ready to maximize your mushroom cultivation yields with a large-scale setup?
The Midwest Grow Kits Complete Large 66Q Monotub Bulk Spawn Growing & Casing Kit provides everything needed for successful bulk cultivation of dung-loving mushrooms in our largest available growing chamber.
Perfect for both beginners taking the next step beyond jar cultivation and experienced growers looking to increase production capacity.
This comprehensive system features a spacious 22.5"x15.5"x12" custom-designed monotub with precision-engineered airflow and humidity control systems. The kit includes two 5-grain spawn bags for robust mycelium development and 10 pounds of premium Select Bulk Substrate - pre-mixed and pasteurized for immediate use after spawn colonization.
The cultivation process is straightforward: inject 5cc of your preferred spore syringe or liquid culture into each spawn bag, allow full colonization, then mix thoroughly with the specialized substrate in the provided monotub. The included vermiculite casing layer creates ideal moisture retention and microclimate conditions for optimal fruiting.
Six self-adhesive monotub filter disks and specially designed incubating hole plugs ensure proper gas exchange while protecting against contaminants. The black monotub liner prevents side pinning and simplifies harvesting and cleanup, while the precision spray mister helps maintain perfect surface conditions.
Precision-engineered 22.5"x15.5"x12" growing chamber provides 66 quarts of cultivation space for dramatically increased yields.
Two pre-sterilized 5-grain spawn bags provide double the inoculation capacity for faster colonization and higher production.
10 pounds of pre-pasteurized substrate with specialized formulation for promoting vigorous mycelium growth and abundant fruiting.
Six filter disks, incubating hole plugs, and precision mister work together to maintain perfect microclimate conditions.
This kit represents the perfect progression for growers who have mastered jar cultivation and are ready to scale up their production. The bulk growing process follows these straightforward steps:
1. Inject 5cc of your preferred spore syringe or liquid culture into each of the provided spawn bags
2. Allow the spawn bags to fully colonize with mycelium (typically 2-3 weeks under optimal conditions)
3. Break up the colonized spawn and mix thoroughly with the Select Bulk casing mix in the monotub
4. Apply the vermiculite casing layer to create ideal surface conditions for pinning and fruiting
5. Install the filter disks during fruiting phase to maintain proper fresh air exchange
6. Use the included mister to maintain optimal surface moisture during the fruiting phase
The larger 66-quart capacity of this monotub significantly increases potential yields compared to smaller systems, making it ideal for those who want to maximize their production efficiency while maintaining the simplicity of an all-in-one kit.
