Flasking in pf tek brown rice flower vermiculite cakes

[Kingjoshua]

I was just wondering if anyone has tried using pf tek to flask orchid seeds. I have never had any luck with agar as I always have had contamination in my flasks. Pf tek is usually use for growing mushrooms. It is made with two parts vermiculite one part brown rice flower and one part water. It is then placed in jars and sterilized in pressure cooker before being inoculated with mushroom spores. As I have not had any luck with agar I was wondering if this would be worth giving a try.
