Well, Im in Australia so theres going to be plenty of sun, i wont need a light. I have no camera, therefore, no photos. As for the amount of space, as little as possible. enough for one, maybe two small plants. Since i dont have many details at this point im really looking for ideas.
what size/ shape to make the reservoir? A length of Pipe, perhaps some kind of malleable bag even.
How can it be powered? A wick doesn't, but a water or air
pump would need its own uninterrupted power source. wind turbine on the roof? (I could actually do this, may just for fun

)
what is the most effective way to train the plants? In the case of cherry toms, training the vines around the reservoir/pipe, conserving even more space?
I dont really have the experience to think out all of the details myself, so does anyone else have anything?
