====Self-Watering Systems====

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 ones, based on ropes, pieces of fabrics, and plastic bottles, and have not found a very efficient one yet.

===Rope-based system===

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===

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===

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 !
