Do you do rainwater harvesting at all Jimi , or is there no point in the drier climate ?
Discussion
Really no point, but capturing from the air using nets and more plants is an option.
Using nets ? To capture the morning dew ?
Yes, great success in humid areas like here. The plants even do it naturally. I theres a lichen that grows on many of the plant and captures water from the air to share.
Also look up water generators. Passive and active ways to get water from the river of air above.
