You’re coming at it with the right intentions. I feel differently about indoor cultivation. Our electricity consumption has a much greater environmental impact than our choice of fertilization/medium; I’d wager a day of electricity has more embodied carbon than a month of any synthetic fertilizer unless you’re relying on nuclear. Synthetic fertilizers like Jack’s are usually made using natural gas.
Indoors, soilless or hydroponic simply deliver more grams per watt. Most people here will produce an excess beyond their needs. One could conclude that, as we get more grams per watt, we should reduce the watts.
If we didn’t have legal restrictions we could all grow under the sun in living soil.
