This way is easy, needs few supplies, costs next to nothing, and provides more plants than you can use.
It is called winter sowing and this is the website:
http://www.wintersown.org/ The basics are: in the winter prepare your containers. Mine are plastic water jugs which I get out of the recycling bins in my neighborhood.
Cut them almost in half, so the top is attached by a little piece.
Put holes in the bottom. Fill with soil. Plant seeds.
Swing the top back across, leave it open. (no cap)
Put outside. Leave outside under 10 feet of snow, or whatever weather conditions are.
In the spring, plants will bloom.
Plants are very hardy and disease resistant.
The website has more details, and there are many different kind of containers you can use.

Not sure how this work with fungi, as I haven't read of anyone using the method with fungi. But it works with vegetables, and flowers, herbs. I recently discovered that using this method it is easy to grow lavender for instance. And the germination rate is usually so high, I end up with more than I can use and give them away.
