Kalanchoe Propagation Experiment (Spagnum Moss vs. Peat/Perlite vs. Water)

In my last video, I hard-pruned my kalanchoe and ended up with a bunch of cuttings I wanted to root. I decided to take this opportunity to see which method was the best for rooting this plant. I used the methods I most commonly use which are straight spagnum moss with humidity bag, 50/50 peat/perlite, and straight ZeroWater filtered water. All cuttings were then placed in bright indirect light next to each other by a NW facing window for 2 weeks.

I checked the roots in the water cup (clear cup) after 1 week but decided to let the experiment run a little longer. Here are my results after 2 weeks:
Water: Produced a few long skinny "water roots" that will need more adjusting once transplanted to soil.
S. Moss: Produced many short stocky roots along the entire stem.
Peat Moss/Perlite mixture: Produced minimal short roots similar in structure to the sphagnum moss but less of them.

Thinking back, I should have used a humidity bag for all of them to equalize the experiment. I will add that the next time I do this experiment. Sorry guys!

Conclusion: Even though the water produced the longest roots, I think I prefer the sphagnum with the humidity bag as I rather have healthy roots with less risk of transplant shock when I pot it up in soil. That being said, if I were to pot into leca, I would definitely go with the water method as there doesn't appear to need an adjustment period.

Thanks for watching my little experiment guys! Please feel free to drop me a comment below with any feedback. Have a wonderful holiday!
