In about 3 or 4 days I had mushrooms sprouting. A week later I harvested nearly 3 lbs from the first fruiting, and they were delicious . Pretty amazing how fast and large they grew. It's been 3 weeks since and there's no sign of a second round. I'll be purchasing again, but I'll probably wait until the weather is a little more moderate, it's been pretty hot the last few weeks.
Lots of mushrooms, easy, great directions. Great gift!
