FAQs
What is included in this refill kit?
This kit contains everything you need to start a new cycle in your existing monotub: one 5-Grain Spawn Bag, 7.5 pounds of pre-pasteurized Select Bulk Substrate, six replacement Monotub Filter Disks, and one Custom-Fit Black Monotub Liner.
Do I need anything else to start growing?
Yes. This is a refill kit and does not include the monotub itself. You will also need to provide your own spore syringe or liquid culture to inoculate the grain spawn bag.
Is this kit suitable for beginners?
This kit is designed for growers who already have a monotub. If you are just starting out, we recommend a complete system from our range of mushroom grow kits, such as the Simple Mushroom Grow Kit Plus, to ensure you have everything you need.
How much culture or spore solution should I use?
We recommend injecting 5cc of your preferred spore syringe or liquid culture into the 5-grain spawn bag for optimal colonization.
Can I use this with a different size monotub?
This kit is specifically measured for a 44-quart monotub. Using it in a different size tub may result in a substrate depth that is too shallow or too deep. For larger setups, consider the Complete Large 66Q Monotub Refill Kit to ensure you have enough substrate.
What is the benefit of the pre-pasteurized substrate?
Using pre-pasteurized substrate saves you a significant amount of time and effort. It arrives ready to use, eliminating the complex and messy process of pasteurizing it yourself, which helps minimize the risk of contamination and gets your grow started faster.
