You can grow plenty of food and plants in PVC gutter gardens! You can attach them to the side of a building or fence or hang them one above the other on chains or rope which makes a nice “green screen” gutter garden like a vertical garden. Make sure you drill some holes into the bottom of each section for adequate drainage.
Use some compost-rich soil and ensure that the plants you choose don’t require a lot of root space. Aim for assorted lettuces and mixed herbs rather than root vegetables.
these are not gutters. It’s hydroponic gardening and there are pipes. But it’s really nice work. Take a look on DIY project http://awesomenessprojects.com/step-by-step-instructions/
