Growing King Oyster Mushroom on coffee ground in a plastic container

Today I will write about growing Pleorotus Eryngii – the King Oyster Mushroom – in a plastic container.

I used a plastic container suited for keeping your spaghetti dry in the shelf.
As substrate, I used spent coffee ground (about 60%), carton (20%), peanut and pistachio shells (20%).

The plastic container I used is made in PP 5 (Polypropylene).

Details:
The container is about 2.2 Liters and I used water at 90 degrees to sterilize it internally, just a couple of washes. In addition, I cleaned it internally with alcohol, as the top lid is big enough to fit my hand inside. Apparently, PP 5 could even support a steam-pasteurization, but I didn’t try that yet.

Growing Oyster Mushroom on coffee ground in a plastic bottle

Today I will write about growing Pleorotus Ostreatus – the Oyster Mushroom – in a plastic bottle.

As substrate, I used spent coffee ground (about 60%), carton (20%), peanut and pistachio shells (20%).

I used an empty water plastic bottle, made in PET 1 (Polyethylene).

Details:
The bottle is 1.5 Liter and I used water between 60 and 80 degrees to sterilize it internally, just a couple of washes. In addition, you can add some alcohol inside (don’t inhale in case you do this, hot water + alcohol creates gasses!). Higher temperatures are also possible, but water at 90-100 degrees modify the structure of Polyethylene 1, so it should be used very shortly.
