Renewal of the hanging tree installation

P7170047 P7170046Today we had a great day at university, changing the installationDSC_2560. We changed one part of the installation, making it pump water round, instead of loosing it into the ground. The water we use is anyway ground water. With the new installation, that is used for only part of the trees it is possible to add nutrients without loosing them into the ground.  Now we can compare the old and the new. For the new installation we had our in-house-pensionado Bernard build software and electronics. Everything worked it seemed! Thanks Bernard!
Also a little cliff hanger for next blog: we have seen some very, very strange things happen with the trees, pictures coming up soon…..
