Gardening has its own associated costs with supplies and requires space
It’s the cost of supplies and garden maintenance and see requirement vs the cost of food at the supermarket
It needs to cost less than the growable food you can buy at the store
You can get away with very little supplies, actually. Basically just a small shovel, the rest be salvaged.
Pots can be made from old plastic bins/containers, soil/fertilizer can be made from food waste using worms, seeds can be made from surprisingly many fruits/vegetables. Pumpkin seeds are right inside the pumpkin, potatoes and beans can be put right into the soil, even tomatoes can be grown from store bought ones.
And while it’s a really cool hobby: you’re right regarding the cost effectiveness. Unless you happen to have a significant plot of land, it won’t make a dent in your grocery bill.
Plastic can leech plastic into your food, I know this personally from getting headaches from using soda bottles as water bottles
And my aunt gets headaches from 5G.
You’re not getting headaches from water bottles. It’s placebo (or nocebo, in this case).
This is not great advice. Using random crap for planters can leech chemicals into your fruits and veggies. Also, you need seed-potatoes to grow potatoes you can eat. You cannot grow edible potatoes from what you buy in a grocery store.
“Random crap” is what’s used in agriculture as well, if you buy a big plastic tub, it won’t leech more into the soil than your coke bottle already did. There’s only so much plastic that can leech out and planters can be used for years, the plastic you’re using around your house gets thrown out in a week or two and replaced. Much higher chemical content there.
And you can absolutely use store bought potatoes, they are clones, there’s no difference between seed and regular potatoes. At most, there might have been something done to prevent sprouting for a bit, but that’s it. You can simply wait for them to sprout, if that’s a concern. You know how I know? I’ve been growing “old” food potatoes in pots for years. Works just fine.
