Psilocybin grow bags are a great tool for growing mushrooms in a small space. These plastic bags are filled with a substrate and then inoculated with mushroom spores or mycelium. The mycelium grows inside the bag, eventually forming mushrooms that can be harvested. Mushroom grow bags are made from polypropylene and have a filter patch that allows for air exchange, which is essential to growing mushrooms. They are autoclavable, which means that they can withstand being subjected to high temperatures for hours at a time during the sterilization process.
These bags are ideal for beginners. They come pre-sterilized and ready to go with a layer of sterilized grain for mycelium colonization and a layer of coco coir substrate for fruiting. They also include a self-healing injection port for easy inoculation using a spore syringe.
The mushroom substrate in these bags is a custom blend of sterilized rye grain, straw, vermiculite, coffee and coco coir fortified with all the necessary nutrients for fast mycelial growth. Mycologists agree this is one of the best and fastest colonizing substrate mixes available.
This bag is designed to be a self-contained growing chamber, but it can also be used in conjunction with a BoomRoom martha tent or Monotub mushroom grower for fuller control of environmental conditions. It has a 5 micron filter patch to block contaminants while still allowing for an optimal amount of air exchange.
The 2.2 mil thickness is the best option for these bags as it’s less likely to tear or puncture. It’s important to sanitize your workspace, scissors, or utility knife before handling the bag. Sanitizing your gloves is also recommended.
