Thanks for a thorough answer. I was not aware LECA would be able to act as a wick to any required degree, but that could be a good solution. I’m having some difficulties picturing exactly what you are suggesting with the LECA drainage layer - do you mean in the soil compartment? And then LECA in the wicking baskets with some polyester cloth going from the soil and into the baskets?
I have seen many videos doing it exactly like I do incl soil in the wicking baskets (which is why I went with it), but you are saying that is a fundamentally wrong way to go about it?
So these self-watering concepts are just wrong then? Loads of videos on them on e.g. YouTube, so I would assume they worked well enough.
How would I change my system into an ebb and flow system? The reason I want a self-watering system is mainly because they are placed in a way that makes it akward to water them and because I want a way to avoid killing the plants when I am away from home which happens often enough.
