I was looking for a alternative to vertical grow pallets and I came up with an idea where i could build a free standing heavy duty shelf above my raised beds. I then could put grow barrels onto the shelves or plant pots. I could also put small grow beds between the raised bed and shelf or I could use some lightweight vertical grow tubes using drainage pipe.
A lot of pallet wood goes to waste in the UK. It would be going near your nearest skip and see what you can find. Maybe you could build this?
