Not sure how much people here will be interested in this, but since i personally want to see more diversified posts here on wide various topics and i just saw that cool Algae Bioreactor post, i figured i’d post this. I have ideas about using those piezo disc mist/fog makers underneath a inoculated log in a container might work well, but i have not experimented with that yet. A plant breeding collaborator of mine in Utah has experimented with putting inoculated logs in a greenhouse and has had good success with that.
Anyway, i just bought a blue oyster mushroom kit from Fungi Perfecti that should work easy to start out with. I am growing that in the garage. But i wanted to try experimenting with creating my own mushroom growing as well. I was too excited to wait. lol. This is what i came up with.
The container is a “honeycomb vase” from thingiverse. I really have no idea what it was initially intended for, though it looks super cool. Probably the coolest thing i’ve 3d printed yet. I am re-purposing it for potentially growing oyster mushrooms. It is printed at 100% infill of biodegradable Coffee-infused PLA (Polylactic acid). (I no longer use ABS). I was planning on putting some “pea-straw” with some Dextrin and Agar. Maybe i should add some other nutrients as well. Anyway, i’m hoping the Dextrin, Pea-straw, and PLA will provide enough nutrients and support for the Oyster Mushrooms. I hope to avoid major sterilization. My only worry is that mold will colonize the dextrin before the oyster mycelium, but we will see.
Got it ready. didn’t take a photo, sorry. But i put in first a layer of Dextrin powder followed by some (TSA) tryptic-soy-agar, followed by some oyster mushroom spawn dowels, followed by a layer of pea-straw mixed in with some Teosinte/Corn “straw”, followed by a few more layers of roughly the same. Also included small sprinkles of some mushroom soup bullion cube powder that has yeast extract in it. No sterilization done. I’m taking a page out of Joseph’s lazy book and hoping that the oyster mushrooms have the ability to out-compete the mold and any other contaminants. I guess we will see. but that is why it is called an experiment… so many things could go wrong… but that is why it is exciting. So ya, that’s my geeky experiment project for this week.
