Pity the Christmas trees, cut from their roots, or left with some poor remains of its roots, those trees will have longing thoughts for a life with water, fresh air and the chance to grow into a glorious tree!

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.

Call for Action! Result from the 22/11/17 Wednesday Meetup November 26, 2017 - 7:57pm

During this gathering (22nd November) we discussed the requirements and the strategies that we need in order to promote the project. (see the photo above for the outcome of our discussion)

We, as a small representative of the core group, came to the understanding that our vision on the Treedripper project needs to be more clear and profound. If we want to be able to promote this project we need to have a persuasive and rigid story to tell about the project and being able to clearly describe it.
