So much stuff online about how to make your own vertical growing system, but I wonder how successful they really are. I suspect that guttering dries out too quickly in hot weather, and that the towers based on a central watering pipe may not distribute the water evenly unless the holes are carefully positioned and decreased as you go down. Gets quite technical all that I imagine.
Stacking crates sound like the best bet but I reckon you would have to water them individually. A 20L crate would probably weigh at least 20kg, which is about all I want to lift at waist height.
Anyone got any experience in this area? Talk me out of it if you wish
