I love SH and came across found this pic online...
It's sort of inside-out SH? So I tried with a recovering NOID Phal that was in typical SH. Just an experiment.
Just after filling the pot with a nutrient solution, the pot began "sweating" so it should be fine for local humidity and moisture. If it works with this "sickly" Phal, it might be a good system... we'll see.
The pot is called an olla and was buried next to plants by Mexican farmers historically as an irrigation system.
