Alright here goes: start simple and learn as you go, observe and document. So a small space setup in Singapore id go for something like: 1 chili plant (main pot) 1 Thai basil 1 spring onion/chives pot 1 tray of kangkong which is basically asian spinach you should be able to find Quick rules - 4-6 hour of sun on a window or balcony, if low light get a 20-40W grow light and have it on 12 hours/day. Water when the top soil is dry and then add an organic liquid fertilizer every 2 weeks. You’ll be able to harvest the spring onions after 3 to 4 weeks, basil 4 to 6 weeks and chili 8 to 12 weeks. 🫡🌀🌱
