Any ideas on secondary source of income?

Farming looks exciting, but will be a capital extensive thing right? Any farming alternatives with less capital?

i was looking at organic farming. turns out that it's a highly time consuming activity that requires constant monitoring, good planning and execution. certainly a highly rewarding business if you get a hold of it but not feasible as a secondary source of income if you wish to do it all by yourself and not invest monetarily in someone else doing it.
