To obtain a little reserve or water in the planter i used a piece of PVC pipe (4 cm diameter) sealed inside the bottle neck with rubber bands, but after some try I discover a better way to do the job, using the plastic cap of the bottle and a piece of hose.
To protect the PET bottle and roots from direct sun, i cut a juta net, found on Ebay for few euros. This natural material give the bottle a rural/vintage look. To hold the mat i used a juta cord.
The shelf is build in cheap pine wood, 12 plank 200x35x5 cm and 4 timbers 10×10 cm, 300 height.
Two cheap 12vdc pumps are set to lift water from the “new jersey” one minute at 7 am e one at 7 pm, enough to keep the right moisture of the planters.
