I would like to start by saying mushroom gardening can be both fun and lucrative, no matter how big or small the operation. Shroom cultivation needs growth medium. How to make commercial growth medium is easy enough, and can considerably cut your costs when growing mushrooms. However, creating it can be a reasonably lengthy process, and you need to think about whether you’ll actually be growing mushies on that large a scale. If you are, then making your own growth medium is just about the best thing that you can do. It depends on the quantity you wish to grow and on the amount of space you have available. If you’re just getting started and would like to study the process, I would suggest that you buy one of the mushroom starter kits. These starter kits usually provide you with a container to grow the mushrooms in, a growth medium, and of course the spores or spawns (mycelium). Generally speaking, growing shrooms from such a kit is extremely easy.
You can sometimes get a good many fruit bodies from a single batch of growth medium and spawn, and they can provide some very nutritious and tasty meals for your family. So a mushroom growing kit is a great idea if you like mushies, or even if you want to learn the basics of farming them. But if you want to grow them on a larger scale, you’re going to need more space. Of course they don’t take up too much space to begin with, but you still need the bare minimum.
You can either buy growing mixture and spawn, or you can make your own growing mixture and buy the spawn, just as you wish. After you go through the process, you will learn how to create your own spawn and keep it on hand for further growing. Making your own growing mixture is likely to lower your operating costs if you’re at all thinking of commercial mushroom growing.
So, if you’re going to be growing a lot of shrooms, but not necessarily on a commercial basis, then perhaps buying some growth medium when you need it is a better way to go. Remember that with mycology farming you can’t just use soil, because mushrooms are rich in protein, and so use up a lot of nitrogen. Well, in case you decide you want to go in for commercial mush growing, here’s how you go about preparing it.
Firstly, growth medium consists of a roughly equal quantity of manure and straw. These need to be mixed thoroughly in a large, flat container with holes in the bottom. As you mix these two ingredients, you need to keep adding a third in, which is gypsum. After the mixture is well mixed, all you need to do is to throw some burlap sacking over it. This sacking keeps the heat that the mixture generates inside. You need to check the temperature of this mixture at regular intervals – perhaps once every day.
