Hi I’m new here, my true area is gardening, but I hope you can help me. In my wiki project: http://www.appropedia.org/Appropedia:Incubator/Gravity_fed_drip_irrigation,_semi-automated#
I’m searching for answers to make gardening as cheap as possible. An example would be 3d printed tube connectors which could be created in the field. I’d be grateful for any help anyone could give. My real goal is to feed the poor, so it would be best if made of recycled plastic.
Thank you in advance!
