Interesting results from experiment 3. This was the small grade media (sieved 2-5mm) test in a wicking setup. This has been the most care-free experiment for me so far, because it's self watering with a reservoir that lasts months. I literally didn't touch these cuttings for 3 months.
From left to right:
- 100% micro leca: hardly did anything
- 100% pumice: best root growth, nice root branching, best leaf growth too
- 50% pumice, 50% terramol: nice roots, nice leaf growth
- 33% pumice, 33% terramol, 33% leca: nice roots, nice leaf growth but less than the 50/50.
- 100% terramol: nice roots, nice leaf growth, similar or slightly worse than the 50/50
Of course single cuttings don't produce statistically significant results, but it looks like pumice is the best media for propagation out of these three. Terramol is also decent, but again leca didn't do much. Too bad pumice is so much more expensive and hard to get here..
The 33% and the 100% terramol both have a second growth point coming, not sure what that says about the media.
During this experiment I also put some random Epipremnum aureum cuttings in even smaller pumice (sieved 1-2mm), also with a wick. Those absolutely exploded, and they weren't even in my propagation box, so for the next experiment I will also try that even smaller grade.
