I have a small 4 unit condo building I am constructing. I was thinking about a green wall for the lobby. Maybe 10x10. I called in an expert and he gave a rough estimate of about 15k$. I used to setup aquariums and have a good general knowledge base about things. Im wondering if this is something I might be able to fabricate myself. WHat are your thoughts on this? could anyone point me in the right direction? Thank you in advance
