Note: I meant to publish my solar wax melter design today. However the pop up thunderstorms prevented the completion of a batch of wax!
I use this system whenever I need to water my trees or blueberry bushes. But the little jets of water don’t penetrate crops that form stands with many vertical stems like my buckwheat.
But for trees and blueberries it is perfect. I just set up the buckets then haul a pair of 5 gallon buckets of water by hand. Over the next ~10 minutes or so, 5 gallons of water is slowly dispersed into a wide arc of the tree’s root zone. I like aiming the jets beyond the stems of the trees or shrubs because as the water pressure lowers as the water drains, the jets will retreat back in front of the stems more evenly covering the rootzone.
For blueberries, this system proves even more valuable as I can direct the arc to water two bushes at once, thus providing 2.5 gallons to each. I can add my normal 2 tablespoons of vinegar per gallon of water in order to ensure the soil pH is not brought up by alkaline (or even neutral) irrigation water. I would not be able to do this with hoses or drip irrigation, at least not without an expensive system. Plus this avoids dampening foliage which is important for crops susceptible to mildew diseases like grapes or asparagus.
