I live in a place where it’s not good weather most of the year. So I tried some indoor garden with grow light somehow it didn’t work the plants seemed to be sick just gave up. Instead I am stocking up some frozen veggies if they really goes short.
If you have a backyard, the least effort - highest output thing you can plant is a fruit tree.
A fruit tree is great, but the proper time to plant one is ten years ago.
No it doesn't. Potatoes are 15 million calories an acre at the low end of yields. That's enough to feed 20 people. At the high end you get twice that. How much land it takes to feed a person is entirely dependant on what that person wants to eat. I grow a balanced diet of meat, dairy, eggs, grains, potatoes, fruits and vegetables for five people on two acres, and I'm not using all that space and I choose to grow low efficiency things like berries because we like them.
