Now these are quite awful, and I need to learn some basics of using CAD software! But I put them in case I forget when I have new ideas!
1. This is an indoor system. Imagine the root-zone (which is below) and the plant-zone being the size of a coffee table. But the depth would be greater, maybe 60cm? And on the front, we have the nutrient + water tank (so easily accessible), and the accumulator tank, and in-between these we have an enclosure for the microprocessors, with a touchscreen on top. LED matrix is attached to the 'coffee table' with a beam, and placed above. Not sure on the height above as of yet. Then we can also enclose the whole plant zone perhaps.
