Enjoy the fruits of your efforts!
I grow my own mushrooms too and when I started I was using really basic teks to get the hand of it and it took me a long time to get where you are. You should be proud!
I've posted an article with instructions on how to grow mushrooms in smaller scale and with more basic techniques and I thought you might find it interesting:
