Mushroom grow bags are a simple and convenient way to cultivate Psilocybin mushrooms at home. A mushroom grow bag is essentially a plastic bag filled with a substrate. This substrate is a mixture of organic materials that provide nutrients for the mushroom mycelium to grow. Once inoculated, the mushroom mycelium will begin to grow inside the bag and eventually form a full crop of mature mushrooms that can be harvested.
There are many different types of mushroom grow bags available for purchase online. Most of these bags are available in a variety of sizes and have different filter sizes. It is important to choose a size that will fit the substrate you plan on using for your particular grow. The best type of bag for fruiting is a larger bag that will allow for ample room for the mycelium to develop before reaching maturity.
Another important factor when choosing a mushroom grow bag is its resistance to contamination. It is important to sanitize your tools and work in a clean environment. A flow hood or still air box is ideal, but any well-cleaned space will do. Keeping the bag out of direct sunlight and in a similar climate will speed up colonization time.
One feature of a good mushroom grow bag is the slip-in filter that allows for fresh air exchange without passing contaminants like mold spores or bacteria. This is especially useful during the sterilization process. During the cool down of the bag, air will naturally be drawn into the bag, but if it is not filtered there is a significant risk of contamination. The slip-in filter solves this problem by simply placing a tyvek filter in between the gussets of the bag before sterilizing. Psilocybin grow bags
