Whatever approach you use, make sure everything is CLEAN. I wiped down my kitchen with chlorox wipes, then sprayed lysol in the air and let things settle. I used small canning jars, sterilizing them in my pressure cooker. Since I had syringes instead of raw spores, I punched a hole in the top of each jar then put a piece of masking tape over it. My medium was vermiculite, and after sterilization (and cooling) I used a cotton ball with alcohol, pulled back the tape, swabbed the entrance and put in the syringe, hitting along the glass in several areas working in a circle (then covering the hole with the tape.
Sorry I'm a little sketchy since my notes aren't close by, but CLEANLINESS is the word because you don't want to contaminate the goods (easy to do). I mixed more vermiculite over a bed of pearlite in a $2 aluminum roasting pan, then covered with foil and 'baked' (sterilized) for an hour at 350d. After the mycelium was showing well in the jars, I dumped them out on the medium and placed the pans in plastic storage bins (from Staples, with the split-hinged tops). I'd keep some distilled water to spray on them to keep them from drying out, but I had good yields and results.
I'll try to add more when I can dig out my notes - best of luck, it's very rewarding. I took some of mine and put them in a blender with 151 Bacardi rum, mixed them good, let it sit, then filtered out. I put that into a plastic flask and snuck it into an Allman Bros show, and within an hour when the band started it was off to the races !!!
