How to Make an Incubator for Magic Mushrooms

Mushrooms are most often found in the wild or it can be cultivated. These magic mushrooms or also known as psilocybin mushrooms can be found in all continents but most species are found in humid woodlands or forests. Magic Mushrooms grow in natural temperature. But for most people especially those growers who are concerned in getting the best yield possible, placing these mushrooms in an incubating jar may not just be enough.

This article will give you the steps on how to make an incubator for magic mushroom. So instead of buying an expensive incubator, copy the incubation process by creating your very own magic mushroom incubator.

Magic mushrooms like any other mushrooms need moisture and warmth. Growing mushroom can be fun and interesting but these little creatures differ a lot from a regular plant. A grower may need to have an incubator intended for magic mushroom. These incubators will help maintain the best condition of this psilocybin mushroom or shrooms. As a fungus, mushrooms need warmth and moisture to grow. So they either grow freely in the wild at a specific place at a specific temperature or it can be cultured so definitely they need an incubator.

To build an incubator for magic mushrooms , you will need the following supplies and equipment:

  • An adjustable aquarium heater (saltwater safe and submersible)
  • A big plastic jug with a tight lid. The jug should be large enough to fit the water heater.
  • A large plastic cooler. Don’t use a metallic cooler. The metallic cooler has wires and electricity.
  • Two small 2V computer fans (or processor fans)
  • Glue
  • Digital aquarium thermometer – this can be bought at your local stores or Walmart. You may need to consider the one with the long wire so the sensor can remain inside while the display is outside.
  • Water
  • Duct tapes and sealers

Don’t use a metallic cooler because of the wires and electricity involved. A plastic cooler’s flexible lid will also keep your wires from getting pinched when the lid is closed and opened.

Steps in making a magic mushroom incubator

Modification of the jug’s lid is important. You need to be able to run the wires through it and still close it tightly even with the aquarium heater inside. The jug should have a water tight seal with the heater inside.

Use a good quality jug to make for easier sealing. You can also use any large plastic bottle, preferably a 2-lliter soda bottle. This process will involve plenty of silicon and duct tape if you’re using regular bottles.

Make sure the jug can seal well otherwise the hot water will easily evaporate from the inside of the incubator and will drop with humidity. Leaving openings for evaporation also means having to open the jug back up to refill it with water regularly. An aquarium heater that runs even partially dry will burn out quickly, possibly starting a fire. Hence, a water-tight seal is necessary.

The jug, with the aquarium heater sealed inside, is now called a heat bomb.

After all the glue on the heat bomb is dry enough, add 5 or 6 tablespoons of salt and fill it up with tap water. Check for any leaks and seal them up when you find them. The heater should be 100% submerged 24/7 to avoid burning out.

To avoid microbes from growing in the warm water inside the bomb, add salt. The salty environment will make it hard for them to proliferate inside the incubator.

You can use any aquarium heater but the Won Brothers Pro Heat is probably the best choice for this method. The Won Brothers Pro Heat heater is a good investment for budding mushroom growers because it has an easy to adjust dial, a remote thermal probe, and a digital temperature display.

Attach the little computer fans by gluing them high on the incubator walls at an angle aiming at the bottom of the cooler. Don’t allow the fans to blow directly onto the temperature probe. Wire the fans to a 12v power supply and tape up the wires to the side of the cooler. The fans should run continuously to prevent the formation of hot spots inside the incubator.

Close the incubator and allow it to run for a few hours. Once it’s running smoothly and you’re sure it won’t explode or catch fire, close the incubator and don’t open it for 24 hours.

Once you open the incubator after 24 hours and you see plenty of condensation when you open it, it means you have leaks inside. Re-inspect and seal up the leaks. The inside of the incubator should remain dry.

After running for 48 hours, the temperature inside the incubator would have become more stable. Use a thermometer to test the accuracy of the heater’s control dial. Set the temperature at 81 or 82 degrees F. If you’re unable to hit the ideal temperature, go cooler. Any temperature warmer than that will only bring trouble for your mushrooms.

At the end of this process, you’ll have a big plastic cooler that’s capable of maintaining a specific temperature. You have completed the steps in building an incubator for magic mushrooms.

Final notes on building a magic mushroom incubator

Make sure there’s plenty of space inside the incubator. The space will help air flow more freely inside the incubator. By allowing air to move inside, heat is distributed more evenly. Without an air current and without space, the heat bomb will become much warmer and can possibly put your growing mycelia at risk.

Don’t overcrowd the incubator with many jars or trays. This will cause hot spots to form and the results will suffer a great deal. Build another incubator instead of filling the incubator beyond capacity.

Depending on the incubator size, the heat bomb will run anywhere from 4 to 10 degrees warmer than the ambient temperature inside the magic mushroom incubator. To maintain the ideal temperature, don’t be afraid if the heat bomb may have to run from 86 degrees to 95 degrees F.
