"Cheap" does not mean "bad" at all. Look at my version. https://www.rollitup.org/t/useful-uses-of-plastic-fencing-net.1068237/

As you know, the R / FR ratio stimulates the onset of flowering and causes the shade-avoidance response. Once, when switching to 12/12, I added 6% FR 730nm to the main Led to stimulate and synchronize the flowering of different strains in the box. FR worked in the afternoon and another 3 hours...

Of course, it does not apply in any way, for two reasons. 1. Drainage is needed to flush out the remnants of previous irrigation from the soil. Or at least dilute them strongly with new solution. If you have no soil in aeroponics, then there is nothing to wash off there. Perhaps at the roots...

The question of bottom and top irrigation is certainly debatable, but probably not in this section. I imagined the "Scale based systems" as a pot with a plant standing on the scale and the scale signaling drying out ((( Now I looked at your system at www.GrowTekUSA.com and everything became...

If watering is not on a timer, then you need to somehow measure the moisture content of the soil. And how will "weighing runoff after an irrigation event down to 1 gram resolution" help in this?

"Anyone doing auto-irrigation based on weight (arduino, raspi, etc.) using a digital scale or similar? I'd like to chat about this, and research a bit. Anybody?" A scale-based system will not come out cheap and reliable. For coconut, it is enough to do bottom flooding once a day on a timer. For...
