In this article I will be talking about growing mushrooms in a jar. There are many different methods of doing this and I will cover some of the basic ways to do it. The most popular method that I have found is using a jar with a mesh lid, and using a small amount of substrate.
There are also other ways to grow mushrooms in jars, such as using a bag of substrate, or even using a plastic container. This article will focus mainly on the jar method though.
The first thing you need to decide when you are going to grow mushrooms in a jar is what kind of substrate you are going to use. There are two main types of substrate, which are:
1) Mushroom spawn
2) Activated substrate
I personally prefer the mushroom spawn because it is much more potent than the activated substrate. The reason for this is because it has already been colonized by mycelium, so it is much easier to start your jar with. You can use either type of substrate, but I would suggest starting out with the mushroom spawn if you are new to this.
The next step is to choose a jar. I like to use a wide mouth jar, because you can easily clean it out. It also makes it easier to drain your substrate out. I prefer to use glass jars for this, because they don’t break when you shake them. Plastic jars tend to crack when you shake them, and then the mycelium can’t penetrate the cracks.
The next step in growing mushrooms in a jar is to sterilize the jar. This can be done in a variety of ways. You can use a dishwasher, or you can boil the jar for 15 minutes in water. You should let the jar dry completely before placing the substrate into it.
Now you need to add the substrate. You want to add enough substrate to fill the jar, and then place the lid on it. If you have used mushroom spawn, then you should not need to worry about adding any substrate. However, if you have used activated substrate, you should add some. Make sure that you add enough substrate so that it covers the entire surface of the substrate. You can add more substrate if you need to, but it is best to just leave the lid on for 24 hours.
After 24 hours, you will notice that the substrate has started to develop. In a few days, you should see the mycelium penetrating the substrate. You will want to take the lid off, and keep an eye on the jar to make sure that it does not get too wet. Also, make sure that you remove any excess substrate that has fallen down to the bottom of the jar.
When the jar starts to show signs of fruiting, you can now put the lid back on, and wait until the jar is completely filled. When you see the first signs of fruiting, you should carefully remove the lid, and allow the jar to sit for a couple of days. Then you can remove the mycelium from the jar, and put it into a fruiting chamber.
It is important that you maintain the humidity of the fruiting chamber. Make sure that you mist the jar regularly, and that the jar does not get too wet.
Once the jar is in the fruiting chamber, you should observe it for a few weeks. The mycelium should start to form primordia, and the fruiting bodies should begin to form. When the fruiting bodies are ready, you should harvest them.
If you are interested in growing mushrooms in a jar, there are a lot of different options available to you. This article has covered one of the most common methods.
