While I like gardening, unironically advising people to grow their own food to cut costs is just bonkers.
It takes months to grow anything, and given the limited space, you can’t grow much anyway. You’ll be lucky to grow 20€ worth of food on your balcony while spending hours doing the gardening. That’s not cost effective.
And that doesn’t even count the cost of materials to get started.
Definitely not against gardening, me and my partners are in the process of getting our garden going in our new place, but dirt alone could easily eat up the cost savings if you have to build out your planters.
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.
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.
Plastic can leech plastic into your food, I know this personally from getting headaches from using soda bottles as water bottles
