I decided to try out growing some mushrooms after my daughter sent me a mushroom growing kit from the SF Bay area. They were oyster mushrooms and worked well, so I wanted more. I trade printing services for the opportunity to pick up coffee grounds from a place in town. I only needed about a five gallon bucket load.
Since we are adamant about having as many car-free days as possible, I try to use the bicycle as much as possible.

The whitish spawn comes in a package.

I placed the bucket outside under some fir trees. It’s mostly in the shade with a couple of slices of sun early and late.

They are growing at Day 28. Soon we will cut just a little to try out. The directions say that 1-2% of the population is somewhat allergic. If you eat just a little and get a reaction, it’s better than eating a bunch.
Just to be sure they were ready, I inquired about the mushrooms.
Looks wonderful and well done on making use of those used coffee grounds!
Thanks for the comment. We are on our third ‘bloom’ now. The little buttons are growing fast. It’s so much fun to watch them and anticipate the harvest.
