Psilocybin grow bags offer a simple, sterile solution for beginner and advanced mushroom cultivators alike. These bags are pre-sterilized with a layer of sterile grain for mycelium growth, followed by a layer of coco coir substrate for fruiting, and equipped with a self-healing injection port for easy inoculation with spores or liquid culture using a syringe.
There are a few ways to sterilize these bags: an impulse sealer, bag clamp or zip tie. These tools can be found online or at your local hardware store. It is essential to properly seal your bag after inoculation. If you don’t, your spores or liquid culture may begin to degrade and will not germinate.
After sanitizing your workspace, scissors or utility knife, and your shroom bag, fold the edges together a few times. Then, slip a tyvek filter in between the gussets. This will prevent contamination from air leaking into the bag during sterilization.
You can grow different types of mushrooms in the same bag as long as it is fully colonized before moving to another strain. However, it is a good idea to separate each spawn bag or sawdust block into its own bag to reduce the risk of cross-contamination and competition between mycelium strains.
Mushroom bags are essentially self-contained growing chambers that can be used as standalone systems or stacked inside other larger growing containers like a monotub or BoomRoom martha tent for greater control over environmental conditions. They also make for an excellent substitute for grow trays in an outdoor environment, especially if you don’t have access to a greenhouse or barn.
These bags are autoclavable, meaning that they can withstand high temperatures during sterilization. When sterilizing them, it’s important to ensure that the bag does not come in direct contact with the base of the autoclave or pressure cooker for extended periods of time. This is because the heat could melt or warp the bags.
One of the best things about a Psilocybin grow bag is its filter patch, which allows fresh air to pass through while blocking contaminants like mold spores. Without this feature, the bag would eventually become contaminated with mold and other pathogens if left unattended.
While the tyvek filter is optional, it’s highly recommended to use it for optimal results. This filter patch helps prevent contamination from contaminating the spawn in the bag while it is being sterilized, as well as during post-sterilization cooling down. It’s especially important to use the tyvek filter when sterilizing bags with sawdust fruiting blocks. This will help prevent side pins from forming on the surface of the block. While not necessary, a rubber band can be placed around the fully colonized block to cut off oxygen to the bottom and help prevent side pins from forming. It’s also a good idea to use the tyvek filter with spawn bags and sawdust fruiting blocks when growing in a monotub or boomroom for maximum efficiency. This will give you the best chance of a successful flush.
