I came upon this interesting solution created for vertical gardening and I myself think it's not a bad one; what do you think!? Of course, it has some disadvantages, but you can't say that it doesn't have some advantages too.
It's for sure a great solution for those indoor gardeners that don't have a lot of space in their apartments and hassle everyday to find some for their loving plants. On the other hand, I can easily imagine something like that incorporated on my balcony, like a little herb tower garden. I can even imagine it like a solution for greening the city, for example vertical garden fences, bus stations maybe!? Vertical gardens in your apartments, offices, in restaurants...ha, ha, ha!! Why not use them for outdoor gardens!? Maybe I overdid it, but I'll be sure to install something like that in my home garden next year. I'm thinking it would be great on my balcony in the hot days and again a great solution for growing herbs in the kitchen, especially in cold winter days. There are some disadvantages, obviously you need enough light, whether artificial or natural. The size of plants you grow in this kind of vertical garden might be also a problem, as the size of your container may be limited, so choose your plants carefully. And what about air circulation, hmm!?
Well, all in all I think if the right choices(regarding the plants you grow) and conditions are made(regarding sufficient light and air) this could be a great solution for a vertical garden, indoors or outdoors.
