I'm being honest. Grow plants, just a small garden if you can, pond for goldfish great etc.. 20 plants including veg. Have you seen a cauliflower seed? It's tiny. Have you seen an organic giant cauliflower? Big. Now that reminds me of the big bang. Garden, it will fill a hole. You don't need a garden for flowers etc. obviously. EDIT: You can still grow tomatoes, peppersw, chillies great to see how nature works.
