thank you so much guys for answering my questions. you really helped me a lot. by the way, i do not grow them, there's a forest near my house where my family and i harvest it. i'll try to make a website and post the photos of the reishi and me. i'm 22 years old and its my first time to start a business, so if anyone is interested to buy, just contact me, we could even chat in skype for better communication
