The air in the Cali desert is dry, not cool but breezy at times. At night the temps can stay in the high 80s and low 90s. The jets I planned on were the arc jets but if you think the spray would be better, then be it.
Water is not cheap but cheaper than many other places, so not a problem. Wanted to stay away from not only heating the pool in the winter but having to cool it in the summer. Electricity, not so cheap. Sort of defeats the purpose of living in this resort paradise with great weather but having to heat and cool 6 months of the year.
