I grew in coco for years. This one was pretty average (11oz) for my 2-gallon pots. Some went as high as 15oz, but this strain was usually around the 10-12oz mark per two gallon pot, with up to six plants per 1200w of vertical HPS light.
Sorry for crashing the thread, but I used to water 4-5 times a day run-to-waste. Pure coco. My own theory - which bore out over many vertical coco grows over more than 10 years - is that the more you water, the more oxygen you introduce to the root zone through capillary action, as well as the oxygenated nutrient solution itself (you can see the black reservoir next to the pot with aerated nutrient solution in it). I never let my coco dry out during lights on while it was being fed. There is no need if the root zone is adequately oxygenated.
I used to grow in bubbler buckets (DWC) before coco, and as you know the roots remain wet (though highly oxygenated) at all times, with very fast growth. Coco was a compromise to help deal with hotter ambient temperatures and proved more reliable in summer. I need to point out that in an aeroponic system, the roots don't really dry out between sprays, they are still moist, as there is high humidity in the system.
Run-to-waste not only continually oxygenates the roots, it constantly flushes them so there is no toxicity build-up. My plants remain green as fuck all the way to harvest, with the odd leaf burn due to the close vertical lighting.
Anyway, not jacking your thread, but I am firmly in the "more you water, the faster they grow" camp.
Nice set-up - carry on!
