I shot those pictures in an old greenhouse that belonged to a garden center for many years and is currently being used by a permaculture garden near our school building.
Every Thursday I work there with a few of my studens. The moment I shot those, they were planting tomato plants right next to me! :-)
This stop valve is part of an old watering system that still works. I shot these pictures with my extension tubes, right after the day I received them. I was just playing with my new toys! :-)
