"Great work guys! I love your site, and am currently working on building my own green wall.
I am having trouble sourcing a trough, though, and am wondering what you guys used?
Thanks for your help!!!"
Basin's are probably one of the more tricky parts of greenwall building. As I've said before mine was made from PVC (a material I wouldn't use again because of it's environmental impact). I would suggest building basins from non-toxic plastic, epoxy covered wood, stainless steel, or something readymade.
If you have a good basin solution please send it in.
