That's ultrasonic aero. It doesn't work for a variety of reasons, biggest prob;em being the discs are not designed for > 300 ppm/tds. Other options are low pressure and high pressure aero. I have experience with them all. None beat simple flood and drain for ease and consistency
Much smaller diameter tubing would increase spray pressure. Have you tried using a deep cycle timer for the plants? Most lp aero fails due to over watering the roots, which look like soggy spaghetti. Start with ~ 3 minutes on 10 minutes off 24/7, but you might drop to 1 minute on/3 minutes off
Smaller diameter tubing will not increase nozzle pressure, it will actually restrict flow and pressure at nozzle.
How do you over water roots? I've ran a cont. spray and they loved it, it was actually the only way to keep temps low in the root zone, the heat was the real killer.
Your wrong about the tubing, keeping the tubing as big as possible up to the sprayer will create more pressure at the nozzle, the drop happens at the restriction not after it, all the smaller tubing will do is cause a pressure drop at the restriction and further drop it through the length but really it's a mute point. As for water timing I have found that it is possible to overwater in my trays but only before roots have establish themselves. I've seen it many times here where ops post a pick of a small seedling with the leaves blotching and turning white due to roots being over saturated before they are establish (this is typically in starter cubes). Once there is a established root structure then I can flood or spray as much as I want but yup it's not economical for lack of a better term. One hurdle I had was to get that initial timing down to a point where the roots thrived but did not dry out or got to wet and started to rot. I now flood three times every 24 hrs with my setup until I get roots growing out the cube well. I tried the LPS setup but went back to flood and drain with chiller
.
I assure you you will see an entirely different and better root structure with a lot more root hairs, which provide more surface are to feed your plants
well you start with incorrect analysis of high pressure aero, so... what else are you wrong about?
Yup ok then
. Is your small tubing like .5" long? The pressure increases at the point of restriction, which is the beginning of the tube, at the end of the tube you now have restricted flow and pressure drop from the tube ..... trust me, my career is built on pressure drop ..... and yes I would stay away from that 80 psig stuff, it's a killer lol.
I haven't tried to clone using a spray setup yet as I've had great luck using the same method for decades although I do have one ready to go, built it a few years ago
. The issue I had was temps in the root zone and switched back with out really giving it a solid try. I'm going back to individual bucket recirc set up I think or DTW to have more flexibility in plant movement for perpetual. Tough choices lol.
So you don't use tubing then? Good choice lol. Yup best way is to tap into pvc, I use 3/4.
