yea, if i go longer the roots wont develop as much higher up it appears, after running shorter off times, like they are at the bottom where some water remains.
And if it gets too dry, then it defeats the whole point of HPA, developing those more efficient but sensitive trichoblast root morphology.
Which leads me to almost conclude that I need a more consistent and smaller average droplet size to get those roots,
easier, consistently.
it's like trying to get a bunch of balls (water molecules with ions) into a bunch of micro fine holes, if they are too big they bounce off, and could damage those fine root hairs.
as it grows it may need less frequent , so instead of 2 minutes, 3-4 minutes becomes more optimal to start allowing the plant/root system access to more oxygen, so the root system isn't drenched, which allows water molecules to combine into bigger ones, being counter productive.
In short.
(Let's say I'm getting 40-80um droplet size when it kicks on and off, when it should be a consistent 10-50um droplet size everytime it cycles)
Finer/smaller average droplet size, consistent, on/ off no squirts from the nozzles as it turns off, using an accumulator tank, solenoids and pressure switches solves most of that if I combined it with this little pump, maybe. Or just get another pump, but they'll wear out faster.
On/off will be frequent for younger plants and slightly differ apart as plant matures, in a proper 10-50um droplet size HPA System
So now that I got that all figured, just need to upgrade my misting system.
Sorry for the wall of text lol.
I said In short, and made it longer, oof.
