Why Should You Grow Oyster Mushrooms?

3 Steps to Growing Oyster Mushrooms

As you plan to grow your oyster mushrooms, it is important to remember a few steps involved in the process. These steps are quite easy to master. In the end, you will find that the mushrooms begin to grow quickly and with minimal amounts of upkeep. 

Inoculate the Spawn

Once you have your oyster mushroom spawn, you will want to mix them with some type of substrate material. Some popular choices include:

  • StrawSawdust
  • Sand
  • Coffee grounds

To do this effectively, it is recommended that you place everything into some plastic bags that you have punctured with small holes. These serve as filters that allow for the free exchange of air. This will start the process of growing the oyster mushrooms. 

Incubate the Mushrooms

Once you have your bags all set up, it is time to get them in a dark location. Depending on where you are in the world, you may need to get a bit creative here. Ideally, you are looking for a dark area that is kept a bit warm. 

The ideal temperature to start the incubation process is between 68 and 75 degrees F. This will jumpstart the first phase of the growing process. Remember that the area should be kept primarily dark and free from the effects of sunlight.

If you can get your spawn and substrate material in the right environment, you will notice some tremendous action taking place within only 10-14 days of beginning the incubation process. You will notice that the spawn begins to grow like a web of roots. This is an indication that the spawn is colonizing throughout the substrate material. 

Start the Fruiting Process

Once your spawn has pretty much colonized the area around the substrate material, it is time to start the fruiting process. This is when you start to see the results of your effort.

You will want to expose each of the bags to conditions that simulate the fall season as much as possible. This means you will want them to be in a place that contains some fresh oxygen, humid conditions, with little light and cool temperatures. While those are the ideal conditions, you will just want to do your best to simulate them as much as possible. 

Once you get the bags into the correct position, the spawn will sense that it is time to start creating the mushrooms you have been looking forward to. At this time, you will notice the iconic small pins that oyster mushrooms are known for start to appear. 

Here are a few key indicators of the fruiting process:

  • The pins will grow quickly – Once you start to see tiny pins growing in the bag, you will notice that they grow into a bunch of full-size oyster mushrooms within a week. 
  • Get ready to harvest in seven days – That’s right. Oyster mushrooms will harvest in only seven days once the fruiting process has begun. 
  • One crop equals three harvests – You will be able to pick your oyster mushrooms three times in just one crop. As soon as you pick a crop, another one will be ready within only 7-14 days.
  • Eight weeks is all that is required for three crops – Put another way, you will be able to pick three different crops of oyster mushrooms within just 5-8 weeks of the fruiting process commencing. 

That is really all there is to growing your oyster mushrooms at home. Following this simple procedure and getting the right environment will give you many healthy items within a short span of time.
