This can also be used on a sandy beach where you dig to the water table, so foliage isn't needed.

Polycarb-glazed greenhouses often get a lot of condensation inside as the plants transpire (?), but I've yet to figure out a way to collect it for reycling to the plants.
I was thinking of using some kind of drip system, by gluing a thin rubber tube to the polycarb lid and placing a drainage system below it that would drip into a large container, this could also work in my greenhouse for extra water.

i would have to do some drawings before i tried it, but in theory if it works and we do have a really bad summer to the point of 76 with water rations, at least we would have the water to feed the crops.
