This is a 4 lb sealed bag with a grain spawn layer on top of a CVG substrate layer of coco coir, vermiculite and gypsum. You inoculate through a self-healing injection port and leave the filter patch to handle gas exchange, so the bag never has to be opened until it is ready. It suits first-time growers and hobbyists who want to skip sterilizing grain and mixing substrate themselves, and experienced cultivators who want a low-prep trial bag. Against separate spawn bags and bulk substrate bought on their own, it trades flexibility in layer ratio and bag size for fewer handling steps and less contamination risk.

This is a 4 lb mushroom spawn bag that holds a grain spawn layer and a CVG substrate layer in one sealed unit. CVG stands for coco coir, vermiculite and gypsum, a blended medium that holds moisture and supports mycelial growth. Because both layers are already in the bag, there is no separate mixing step.
The bag is pre-sterilized in certified autoclaves, which gives a clean starting point and helps reduce contamination risk. A self-healing injection port lets you inoculate with spores or liquid culture while the bag stays closed. The port reseals after the syringe needle is removed. A filter patch allows gas exchange while helping keep contaminants out.
The single 4 lb bag suits home growers, first-time cultivators and small trial runs. Experienced cultivators can also use it as a low-prep test bag.
