Is it right to grow oyster mushrooms on cotton-seed & use Formalin + water for pasteurization?
It's my first time growing oyster mushrooms. I am using "cotton-seed" as a growing medium since it's the material I can find in my area. And for pasteurization, I add "Formalin" into water and soak it for 2:30- 3:00 hrs. This is how the instructors in my area told me. Do you think I'm doing it the right way OR Do you have any suggestion on how I should grow it better???
