Interesting. I've seen a huge difference in yield as pot size changes but never seen the numbers on it.For me it follows container size roughly if I do my part. I'm in ffof soil with bottle nutes. So for 2 gal pots 2 ounces is about right. 3 gal pots 3 ounces and so on and so forth. Now hydroponics changes everything. I've gotten over a pound in a 3x3 with a recirculating dwc that I made. Coco around 30% more than soil roughly. As always ymmv. I run either cobs or Samsung boards for lighting BTW.
Yeh, hydro's very different.
