Having very little space...i have to grow most of my plants vertically. I havnt looked at any fancy systems... I just have a fence, on which the previous owner has put lots of strong nails at intervals. Then he just wound wire around and between then in a pattern. Im grownig what i can on these.
So far, i have beans, peas with extra string holding them, butternut pumpkin, passionfruit, grapes, new cucumber, tomatos, capsicum, support for the corn.
Im thinking about trying a rockmellon or watermellon next year as well, however they might be a little big for the fence.
Other verticle things i did was hanging baskets, the water from the. Drips into the pots below to save water. The plants below, tomatos, climb up the poles supporting the porch.
Other than that... I have seen somebody nail old plastic flower pots to a fence in a pattern where they all have bits exposed the the top of the fence. (sorry hard to explain) then they ran a drip hose along the top of the fence and all the water ran into the pots. Water came out the bottom of the pots and into the next ones below. Other than thatt you could just water them.
