Mini-Teaser Workshop: Connector pipe and tube December 6, 2017 - 4:40pm

These people understand that tubes and valves for dripping cost the money that is not there. That's the reason the TreeDripper project designed no-cost tubes and no-cost valves and we offer to teach them how to make that. Even in the only 30 minutes that we have.
