Out here, there are no perimeters ! In the bushcountry of Saloniki, you easily loose the feeling for time and space. There fore the jinn made a JINN.TV schedule to keep control over his timeless feeling and to keep organized. This is Africa !
Now – to a further lesson of building earthships. Carton is not the best material to prevent dirt from running out of the tires, better is to use plastic bags instead. Its also possible to use gardening planes as long the material is flexible and ajusts it self with the dirt and tire below. The second layer of tires has to be carefully made like the first layer, because it also belongs to the fundament. Its really important that you level all tires horizontally and vertically ! Pound the tires and level it ! Also check that 3 tires in a row are on the same level. Do the 2 level carefully, stability of the following layers will depend on a good leveling ! Pound again, level again till the tires are compact and streched. Over and over > Fill the tires till they are packed well and even.
