Vertical farming, the best solution to support an ever growing population or just a scam?
IMHO it has a lot of potential but not being able to grow grains really is something that should be tackled sooner rather than later. But I could see this being used by self sustaining communities to provide lots of food while using very little space. And it's technically more environmentally friendly than just using vast stretches of land to produce the same amount of food.
Lower part of my garden receives less sunlight. So I will have to raise the bed up. My concern is not grains but vegetables and herbs. I don’t believe I can justify growing grains in the garden. What I have to experiment next season is if raising the whole table is better (more soil) or use stacking to raise the height(vertical farming).
Although I was more talking in the hydroponics sense, this also reminded me you can do something similar with soil. Also good luck with that I hope you get lots of herbs
