I mentioned this once before and since the weather is not too flash I did a simple diagram.
Rather than using my original solid braces I thought it may be possible to put about six guy wires from the top and simply wire the draincoil onto them as you wind it round. The pots would be net and there would be no media, probably spray it with white paint because of heat gain. At the moment it looks like it takes up the same footprint as ground beds but that is dependant on the overlap of the spiral, theoretically I suppose you could just wind it round an upright barrel and cut the pots in at an angle.
Obviously not for things like tomatoes.
Aside from my crap drawing skills I would appreciate any constructive criticism
