So, if I understend the numbers properly, Hydroponics 1 will convert 1000 water into 300 food and 300 O2 - so for 1000units of delivered cargo I'll get 600 units of supplies, where as if I deliver the resources directly, I'll get 300 food, 300 O2 and 400 water (which isn't getting eaten by the Hydroponics). I fail to see how hydroponics is supposed to be a better choice than just hauling the supplies. Even with the production bonus it's a net loss, because you get 600 units of supplies out of 850 units of delivered cargo. Is there something I'm missing?
