Why would I choose cheap boring ones though, also, you’re not my hobby allocator. My constant need for novelty and complete lack of discipline are.

Gardening can cost zero money.

Pot: an empty can, joghurt package, cut off plastic bottle

Dirt: go outside and scoop some up, people who make their own compost often give some away

Seeds: fruit and vegetables from the supermarket often include free seeds (e. g. bell peppers)

People also give away plants and cuttings all the time.

You will need a spot that gets some sunlight though.

Wish someone had told me that before I bought a plane. My new hobby is aviation
