Using the Magic Bag is simple. Inject your liquid culture or spores into the mushroom grow bag. Keep the bag in a warm, dark environment with no light (between 72 and 80 degrees is ideal). Wait a week or two.

Once the bag starts turning white (that stuff’s called “mycelium”), give it a shake to make sure the mycelium spreads throughout the whole bag. Wait another few weeks.

Once the bag turns completely white, your mycelium are ready to become mushrooms. Cut the bag open to give them some air and a little light (a few mists of water from a spray bottle every few days helps too). Pin the side of the bag with the provided paper clip so it’s loosely closed with enough room for a little air to seep in. Your Magic Bag should start producing mushrooms in another week or two. Pick them right before the cap separates from the stem. Your mushroom grow bag will keep producing mushrooms for another week or so (each crop of mushrooms is called a “flush” – your Magic Bag should produce 2 or 3 flushes). Once it’s done producing mushrooms the insides of the bag can be composted and the plastic bag can be recycled at a designated soft plastics recycling bin.

The all-in-one design of the Magic Bag is different from typical mushroom growing methods that have many disparate parts and separate fruiting tubs. The Magic Bag simplifies and streamlines the mushroom growing process.

Unfortunately you can’t reuse our mushroom grow bags. Once it’s done producing mushrooms the inside of the bag can be composted and the plastic bag can be recycled at a designated soft plastics recycling bin. But remember to pick your mushrooms and let your bag keep producing mushrooms. It will produce 2 or 3 “flushes” (aka ‘crops’) of mushrooms.

You should inject 5 CC’s (mL) of spores or liquid culture into your Magic Bag. Too little, and there won’t be enough material to latch on and grow. Too much, and the substrate will become too damp and become susceptible to mold and mildew.

Grow times will vary depending on the strain you’re using but typically your bag should start to produce mushrooms by the 8-10 week mark. Colder temperatures will prolong growing time

Our bags will produce around 2 to 3 ounces of dried mushrooms. For slightly higher yields, you can transfer your bag contents into a tub to fruit (fruiting is the last stage of the growing process when actual mushrooms are produced). We recommend fruiting right in the bag though, as the bags are designed for this. It’s also easier (less hassle) and there’s less chance for contamination.
