In this video we show you how we grow mushrooms at our indoor facility in Hadley, Massachusetts. How do mushrooms grow? Watch and find out

How do mushrooms grow? The process is certainly different indoors than it is outdoors.

As you can see in this video, we make sawdust blocks. In this video we showcase our chestnut mushrooms growing from these sawdust blocks.

The chestnut mushrooms in this video are shown in different stages, from when they are just pinning as young mushrooms, to full-grown and ready to pick.

How do mushrooms grow from our blocks?

The blocks that our chestnut mushrooms are growing on in this video are made from 50% sawdust and 50% soybean hulls.

To grow these mushrooms we start by growing out the mycelium. Once the mycelium is grown out, we cut a large X in the plastic bag. Sometimes this cut will go from corner to corner. The mushrooms then fruit from where that X was cut.

Mushrooms, like people, breathe in oxygen. So once the cut is made, the mushrooms will grow out into the high-oxygen environment.

Mushrooms also really love light and are positive phototropic, meaning that they will grow towards the light. This helps them to grow from the bag as well as they prefer to grow towards a high-light environment.

How do mushrooms grow: The four main things to consider

  • Lighting
  • Oxygen
  • Humidity
  • Temperature

As you can see in the video, we have humidifiers in our mushroom farm to add the appropriate amount of humidity to our grow rooms.

How do mushrooms grow: An easy way to grow oysters

You can purchase ready-to-fruit Fungi Ally mushroom blocks, which will help you avoid much of the tricky lab work and get you growing mushrooms as soon as possible!

Our mushroom blocks are about 5.5 pounds of supplemented sawdust, measuring about 12″x6″x8″. We offer an array of mushrooms for sale this way, including:

  • Blue oyster mushroom
  • Pink oyster mushroom
  • Yellow oyster mushroom
  • Shiitake mushroom
  • Lion’s mane mushroom
  • Other species for custom orders

Each block costs $5 and the minimum order is 50 blocks, which can involve a mix-and-match of strains. The blocks are ready to fruit when you receive them, so they need to be stored in a walk-in cooler until initiated. They can last for about 3-4 weeks in a cooler before they start fruiting in the bag and yield is decreased.

These blocks fruit in flushes. The first flush usually is 10 days to harvest and yields an average of 1 lb. You then wait for about another two weeks and they will fruit again, about another 1/2 lb. It is possible to get a third flush as well, which is around 1/4-1/2 lb. Shiitake blocks particularly need to be soaked for about five hours to initiate 2nd and 3rd flushes. Many mushroom farmers do this in low tunnels or other outdoor structures during the warmer months.
