I moved in with my bf, who I guess you could call a prepper, and we grow most of our own food. We've been harvesting winter crops for the last few weeks and preparing them for storage. I'm eating some right now since we got absolutely massive cauliflowers, easily 3x the weight of anything store-bought, and they make for delicious cauliflower cheese casseroles.
My number one tip is to avoid expensive pesticides, build a timber frame and use camping magnetic strips to make anti-pest cloth hoods for your plots of any size that are miles more effective, won't be blown down in the wind, can be easily removed for harvest and maintenance, and only need bits replaced every 6 months or so for about $5 of material.
My favourite thing is caring for the crops every day by hand watering, inspecting and keeping them healthy. Weirdly it gives me babymaking brooding feels.
