I love the idea of a vertical garden, especially for Semps, etc. I just think the plants would be so crowded. How do they put out their little chicks if they are so crammed close together? Do they live long all crammed in like that? Just curious if anyone has any experience in that regard. The pallet thing would rot. I don't know how long it would take though. The plastic ones you buy would last longer I bet. I saw some for a reasonable price today, but I need to research this more before doing it. I know the plants are going to be crowded and will probably suffer.
