Bulk Substrate Casing Mix Kit FAQ
Do I need a bucket?
Nope! Our dry mushroom substrate kit is self contained. You achieve sterile substrate right in the bag by adding water, the supplied calcium supplement, and microwaving. Made hot and fresh the way ma used to.
How long does it take to make your kit?
Expect a 5-6 hour process, consisting primarily of cooldown. The substrate must be at room temperature after sterilization before it’s ready.
Can this kit be used as a substrate for spawn beds or as a simple casing?
Yes
Why Add Calcium to my substrate or casing layer?
pH Buffering:
Many casing layer materials, like peat moss, are naturally acidic. Adding calcium carbonate (like agricultural lime) helps to raise and stabilize the pH of the casing layer. This is important because:
Optimal pH levels are crucial for mushroom fruiting.
It helps to suppress the growth of unwanted molds and bacteria that prefer acidic environments.
Structural Support:
Calcium can also contribute to the structural integrity of the casing layer.
Nutrient availability:
While the casing layer is not the primary food source, the pH buffering provided by the calcium, helps to make other nutrients more available.
Adding calcium to a casing layer is primarily about creating a more favorable and stable environment for mushroom fruiting.
What is a spawn bed?
A spawn bed is created by combining mushroom spawn (grain) with a nutrient-rich substrate. This mixture is then spread out evenly in a pan or tub. The mushroom colonizes the contents of the spawn bed then fruits.
