His examples were hyperbolic as an illustration of outer bounds. What contest are you trying to win, exactly?
I think the way you presented the initial premise of this thread is total bollocks. Had you expressed similar thoughts with more nuance and understanding I might have agreed. But I think you’re looking to be “right” more than you are trying to help. A lot of the discussion has been good, in spite of many of your posts being confrontational garbage that serve no useful purpose.
For the record: I currently mostly use DWC with 4 plant sites and can pull well over a lb out of a 4’x4’ tent, with zero veg from rooted clone and very little effort. No environment control beyond central air and fans. I really might hit close to 2gpw, with essentially no veg time, in the next year. Especially in my little SOG tent. I only have to check on it every week or so. I have also grown in coco, and soil, using light from CFL, T5HO, blurple LED, HPS and HLG 550 RSpec (which is well worth the scratch) - all on a very small scale.
