High there!
Try to make it like this:
Thats the way I do..
try to get some glasses used for marmelade and put the fertile soil in 3/4. after this, put some dry vermiculit (mineral used for the fertile soil) over 1/4.
Put it in the Microwave 25min for sterilizing, after this clean the lids of the glasses with alchol, strillium for example, and screw them lightly on the glasses. take a nail and hammer and put 4 holes in the lid, every side 1, Nord, South, West, East, and place some tape over the holes. In every taped hole, you inject 1/4 of the spore spyringe. Put them in a dark room...with about 27°C and let them incubate for 7 to 14 days, when the mycel has completely taken the glass, open the lid and turn the glass. So you can put it in the terrarium covered with kitchenwrap -> or growbox completely(without the glass). Just wait 10 days and harvest.

'edit' Never ever touch something with your hands! Keep it very sterile, sterilize everything! and keep attention on your hair and mouth.
