I've run my drain line into the planter behind the house. We'll see how the shrub likes it.

In The Netherlands there is an initiative selling growth-kits for this (Rotterzwam). They supply a bag of spores, a bucket and a number of instructions (these are also in Youtube). Really cool if you ask me.


I love this idea. I hope I can find such a kit to grow oyster mushrooms in Indiana.

I once had a scare with spent espresso grounds. I had a rhubarb plant next to my white garage. I was spreading the grounds around the rhubarb. One day in the hot August sun, I witnessed the grounds spontaneously combust. I assume it was the sun reflecting off the white garage onto the coffee. I wouldn't have believed it if i hadnt seen it. Anyhow, i quit doing that.

I put all my brewed grounds in my potting soil directly, even working it into the top inches of already planted pots.
