 I also looked for diverse [[http://www.hellocoton.fr/to/dIgI#http://www.comment-economiser.fr/arrosage-automatique-fait-maison.html|self-watering systems designs]]. I tried diverse systems, based on ropes, pieces of fabrics, and plastic bottles, and have not found a very efficient one yet.
+===Rope-based system===
+{{ :michka:know-hows:img_4882.jpg?400 |}}
+Water flows slowly from the bottle to the soil through the rope, by capillarity. It works but does not waters the soil enough.
+===Fabric-based system===
+{{ :michka:know-hows:img_4895.jpg?400 |}}
+It is supposed to work almost the same way as the rope-based system, but does not seem to be as efficient - it may be a design issue. A new version made of a continuous piece of fabric - and not small ones tied up together - should be tried out.
+===Water-layer based system===
+{{ :michka:know-hows:ku-xlarge.jpg?400 |}}
+I found this design [[https://www.youtube.com/watch?v=Ffe7JfYyBFE|on Youtube]]. It works well (as long as you do not don't forget to plug the bottle correctly). However, the soil was too soggy with this system.
+===Good neighbour system===

+After these failures, Rasa offered me to take care of the seedlings when I am away, and I am very grateful to her !
+====Windshield====
 After dramatic death of my first seedlings during a windy day, I started to think about how to protect the plants on the balcony from the wind. I have currently installed a piece of transparent plastic and some glass windows as windshields. I may move towards a system based on plastic bottles.
