I'm just getting into growing mushrooms right now. I purchased a kit, that comes with mushroom spawn instead of spores. Based on what I have read, with spores you need to create the substrate (growing medium) and keep it in a sealed container. Inject the spore solution into the substrate (keeping things sterile is very very important) and sterilize your container of substrate and spawn in a pressure cooker for about an hour at 170 deg F. Then you need to keep the container of substrate and spore in a dark and warm place (26-30 deg C) for about a month (Im a noob so my time may be off) once your container looks like its full of white hairy moldy stuff, you need to remove your "cake" from the container and soak it in water for about 20 hours. Then you put your soggy cake into a "fruiting chamber" or a grow chamber. Maintain 13-15 deg C and keep it humid for about 4 weeks. Then pick your shrooms by cutting them at the base, not pulling them out. That is your first "flush" you can soak your cake for 20 hours again and repeat the fruit chamber procedure for your second or even third flush.
It sounds like your kit is only made for fruiting mushroom spawn and not spores. Mushroom spawn is different from mushroom spores. Simply injecting mushroom spores into a fruiting chamber, probably wont work. If you have mushroom spawn, then a sterile fruiting chamber and sterile substrate should give you the mushrooms you want to grow. If you have mushroom spores, you are going to need to make cakes and let the spores do their thing in the cakes for a month at 26-30 deg C in the dark before moving on to the fruiting chamber, or growing chamber.
