tigerlily never thought about Sulfuric acid. I am not possitive but I think it can eat cement?? I will have to look into it. The vinegar just seems safer to me but I will have to spend a bit more.

As for it being a living wall. This side will have a mister that kicks on every 30 minutes for about 30 seconds. The wall should be kept fairly damp. The other wall I plan to work with is going to have a liner under it and I plan to drip water off it constantly and recycle it. I was thinking of adding the same thing to this side but had already layed down the the first few rocks so adding a line was out of the question. I have also thought about adding a well like drain in the middle of the greenhouse and sloping all the cement towards that drain and recycling all the water being used to some extent. I will not work on that for sometime though.
If any of you ever get a chance to go to Atlantas high altitude house they have a really nice system were water from the greenhouse drains down into a under ground tunnel and air is blown through the tunnel and back out the top of the greenhouse as well as the water is sprayed back through the mist. It make it very cool super humid and no nutrients in the water very pure rain like effect. They are growing some amazing stuff that most people cannot grow high altitude is very hard to duplicate. Here is a photo of the greenhouse. They get spaghnum moss to grow all over the place and nepethes and orchids are weedy their.
