if not i need some alternative substrate for shroom cultivation.
Yes, you absolutely need vermiculite. That is what will keep the eggs moist enough to incubate properly. I have been breeding for several years now, and I don't do anything more than put the eggs in an empty sour cream bowl with vermiculite. The vermiculite should be moist to the touch, but not soaking wet. I keep it lidded with a few small holes for air. I recommend opening it everyday or two just to check on the eggs. Keep the temperature constantly between 79-88. If all works fine, you should have little ones in 6-12 weeks. Good luck!
