Better than even a little light is no light at all. They also like a stable temperature range, so make sure that stays within the range of between fifty and sixty degrees Fahrenheit - anything more than that will cause problems for your mushrooms. You need to be careful to keep out any draughts. The air needs to be moist, because that's just how mushrooms like it. If you've looked at any mushrooms growing in the woods, you'll have noticed that they don't exactly grow in the soil. Similarly, when you grow them in your greenhouse, or even in a garden shed, you're going to have to arrange (or buy) a special growing medium for them.

There are two ways of going about mushroom growing, and the method that you choose will depend upon just how many of these fungi you plan to grow. If you're starting out on the very smallest scale, a log of wood should do just fine for a growing medium. Yes, that's absolutely right, you can grow mushrooms on a log of wood. And why should that surprise you - haven't you seen them growing around tree stumps in the woods? All you need is a good log of some reasonably hard type of wood - oak does just fine.

Take that log and make a few reasonable holes in it, and fill each of them with some mushroom spawn. Then let nature take its course. If, on the other hand, you intend to grow mushrooms on a larger scale, you're going to need to bed them down in trays filled with a special mushroom growing medium. Well, I did tell you before that they won't grow in soil. What you're going to need is some compost mixed up with straw or a mixture of straw and horse manure. You can plant the mushroom spawn in this, and your mushrooms will grow just fine. If you need to grow more mushrooms, you'll just have to set out more trays and set aside more space for your mushroom growing.
