Midwest Grow Kits Complete Large 66Q Monotub Refill Kit
Ready for your next cultivation cycle but don't want to buy a whole new setup? The Midwest Grow Kits Complete Large 66Q Monotub Refill Kit is the perfect solution for experienced growers. It provides all the essential, high-quality consumables you need to get your next grow started quickly and affordably, ensuring continuous cultivation without the extra expense.
This comprehensive package is designed as the ideal companion for the Complete Large 66Q Monotub Kit. It includes two premium 5-grain spawn bags, ready for inoculation with your favorite spore syringe or liquid culture. Once colonized, simply mix them with the 10 pounds of our pre-pasteurized Select Bulk Substrate, which is specially formulated to fuel vigorous mycelial growth and produce abundant yields.
To ensure an optimal growing environment, the kit also comes with six replacement monotub filter disks for perfect air exchange and a custom-fit black liner. The liner is crucial for retaining moisture, preventing side-pinning, and making post-harvest cleanup a breeze. By bundling these essential mushroom growing supplies, you save both time and money compared to purchasing each item separately.
