3lbs Sterilized Grain Bag with Injection Port

Our 3 pound grain spawn bags are sterilized and ready for inoculation.

Unicorn Bag

Our mix and bag choice (Unicorn Bags 10T) optimize growth rate and size, these bags require only a spore syringe or liquid culture for inoculation via the injection port.

Injection Port and Filter Patch
Each bag features a self-sealing injection port for ease of use with spore or culture syringes. A 0.2-micron filter patch ensures clean air exchange while keeping contaminants out. (Note: Injection port color may vary.)

Cape Mycology Grain Mix
The blend includes millet and rye, selected for their nutrient content and hydration to support healthy mycelial growth.

Millet’s smaller grain size increases the number of inoculation points, promoting faster colonization. It is also less prone to contamination due to its lower endospore load.

Recommended Use:
Use 1 lb of grain spawn per 5 lbs of substrate. To inoculate the grain, 2.5-5ccs of spore or culture solution should be injected into each 3 lb bag.
