I have chosen from all variety of strains - Cubensis Mexican.
I used wheat, it was colonized in glasses in volume 200 ml.
After colonisation grain has been mixed with a small amount of vermiculite.
I waited some days and have transferred "pies" to a hotbed.

My hotbed - a garbage package. At the bottom there is some water.
I do not use additional illumination, the usual daylight suffices me.
Unfortunately I had no access to the camera during first three waves. Here a photo of two pies after three waves:

And it is the third wave from the big pie:

In total the weight of first three waves has made 13 gramme of dry mushrooms.
Photos of the fourth wave:






I yet did not weigh a crop.
So I will continue the supervision in process of information receipt if it is interesting to someone.
P.S. Excuse for my awful English )
