This page will be to help follow the first actual test of the old idea to use grapevine cuttings to grow oyster mushrooms
Introduction
Context
This is a part of an idea that came out of the Biofest in Greece. To note: a second one will soon be run again, 22-26 April 2026
There we discussed using olive branch cuttings to grow mushrooms. So, the idea was that here, in a grape growing region, we could try similar, with grapevine cuttings.
Objectives
to see how well mushrooms might grow on 'waste' from ordinary agricultural practices.
- This is our first test with grey oyster mushroom grain spawn on chopped up grapevine cuttings
Background & Inspiration
Some theory needed ?

Biofest first of all.
Run / prototype #1
Setup description
General principle: chopped up vine cuttings (thx to Antoine of Polymeka pictures to share), then got sterilised at Floyd`s and inoculated...
As of last week, early April 2026 (2 bags are still at In Pompaples under optimal growing conditions.
& one bag is in Hackuarium, under a box
Block with mycelia - grain spawn inocula) fully colonized in about a week! (Floyd says this is 2x faster than usual...)
Step in pictures: especially sharing pictures in Biofest II drive
Floyd presents at last #OH of March 2026
after air out of block, x2 Xs cut, and put in humid box with light...
Update 8 April 2026:
- all done for the 2 blocks at Floyd's under optimal fruiting conditions - 9 days to gorgeous harvest (weight and taste test to come)
- 1 block at lab under a box (wet each day) - after 9 days bottom set done, more to come...
Run / prototype #2
