-<!-- Indiquez ici une petite introduction au projet, qui apparaîtra dans la liste des projets. -->
 An exchange project has been set up between Universcience and the Cluj Cultural Center in Romania, as part of the France-Romania season. The first part of this exchange consists of a FabLab residence of two Romanian Biologists from the University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca, who, together with the Carrefour de Numerique team, will work on building up a fully automated terrarium.  The residence runs from March 19th to 23rd.
-Once the Terrarium is in place, the objective of the residence is to be able to check & register  the parameters of soil & air humidity, air temperature & ventilation as well as light intake of the terrarium and to build up an automatized system for watering, heating/cooling, lighting and air flow in the terrarium.

 The system will also be used to study different aspects of the Terrarium Eco-System. How do plants affect each other, what is the correlation between humidity, temperature and light intake, what are the optimal humidity, temperature and light values for a favorable plant growth?

   * **A terrarium** > the box: can be found in any petshop or you can recycle an old aquarium, ours is a 40x25x25 cm (LxWxh) glass aquarium
-  * **Clay balls** > to cover the terrarium floor (1st layer).
+  * **A vertical plant wall** > we used a polystyrene board with glued hydroponic planting mesh pots.{{ :projets:terrarium:pot-ajoure-pour-hydroponie-ghe.jpg?100|}} you can design your own as long as you keep in mind that the plant pots need to enable roots and soil to reach the filter tissue
-  * **A piece of polystyren** > glue the hydroponic planting mesh pots net on it. We used a glue gun to do so.{{ :projets:terrarium:pot-ajoure-pour-hydroponie-ghe.jpg?100|}}
+  * **Clay balls** > 1st layer: to cover the terrarium floor - used for draining the excess water from the soil - you can find them in bigger garden shops
-  * **Plants** > Choose dwarf plants, they won't grow too much (ask when you buy it). Examples : //Fittonia// sp, //Syngonium// sp, //Pilea cadierei// Sil, //Nephrolepsis// sp, //Ficus pumila// sp.
+  * **A piece of geotextile** > 2nd layer: a felt-like non-woven textile to cover the clay balls and the vertical wall. - this tissue will keep the soil from mixing with the clay balls, depending on the texture the textile will absorbe the water and keep the soil wet for a longer time, you can alternatively use a mosquito net. > https://study.com/academy/lesson/what-is-geotextile-fabric-definition-types.html
-  * **A piece of filter tissue** > to cover clay balls and a part of the polystyren and pots (2nd layer).
+  * **Soil** > 3rd layer: Find a a kind of soil made from sphagnum moss. A soil with a little bit acidity (here PH 4.8) which encourages plants growth.
-  * **Soil** > This is the 3rd layer. Find a a kind of soil made from sphagnum moss. A soil with a little bit acidity (here PH 4.8) encourages plants growth.
+  * **Moss** > 4th layer: to cover everything, used for aesthetics, you can also use dry leafs

 **Electronic part**
-We choose to use arduino to control
+We chose to use an arduino uno to control:
-  * the light
-  * a computer fan
-  * an air humidity and temperature sensor > DHT 22
-  * a soil humidity sensor
-**1/ Light**
-We use RGB LEDs that have one commun cathode.
-Arduino program : {{:projets:terrarium:rgbled.zip|}}
+  * RGB lights: Red & Blue lights are helping plant growth, while the green light mimics the sun-light and makes the terrarium look pretty :)
+  * a computer fan: to enable air-flow and to balance the internal air-humidity
+  * an air humidity and temperature sensor > we used DHT 22
+  * a soil humidity sensor >
+  * a water pump > we used VMA421
