>Hydroponics are limited to low-calorie foods such as lettuce, herbs, spinach etc due to constraints in the method itself. Why do you say that? Hydroponic setups often produce tomatoes, peppers, eggplants, strawberries, etc are all quite popular. https://www.biotecharticles.com/Agriculture-Article/Hydroponics-Cultivation-of-Wheat-4374.html https://www.biotecharticles.com/Agriculture-Article/Hydropon... >High calorie and/or high fiber foods require complex rhizospheres which is currently only found in healthy soil. Mainly root veggies or large things that are unruly like a watermelon. More of a practicality problem. I have been eyeing that root veg drip hydroponic system. You can absolutely grow all the foods hydroponically. Not sure about those rhizospheres. >To add injury, the substrate used to provide nutrients to hydroponic plants either require petrochemicals or other plant material (compost, husks, seeds...) to mimic a complete nutrient profile. This hasn't been true for decades. I think you touched on the real big problem "petrochemicals". Oh ya we just found the problem. https://ntrs.nasa.gov/api/citations/19900009537/downloads/19900009537.pdf https://ntrs.nasa.gov/api/citations/19900009537/downloads/19... >Perhaps there are solvable problems, but given the already high costs and limitations, hydro is not an option if our ecosystems collapse. Did you know when you exclude the illegally seized Moroccan fertilizer we have about 20 years left of current day farming? I wonder about glyosophates eh.
