These are some of the better pictures, they were taken to profile the restaurant directly, not so much for the wall itself, but I how they suit.
The wall is made up of 1700 plants, over a 6m high x 4m wide wall, that returns around on one side (the left) so its double sided for 2m .
The plants are mainly peace lily's, boston and hen& chicken ferns, and spider plants, planted into 3 layers of Hydrotech felt (which we got from you), secured back to the same ply that you used, fixed to a steel frame. We used steel as the weight of our wall was so much.
The trough at the bottom is custom made stainless steel trough, clad with raw steel for the right look - the water in the pump is then reticulated through pipework at the top of the wall by a pump. We have 5 hydroponic lamps set up to go on for 8 hours a day overnight.
We PH test, add nutrients (including clearwater), clear blocked pipes, and check all plants twice weekly... and flush out the trough once per week...
so two months in, the wall is really flourishing, it takes a fair bit of work to keep it this way though! The great thing about your style of wall is that you can get it looking amazing from the first day of installation, and you can put it together yourself if you do your homework, and get some good people to help you out.
The smell has diminished substantially also with the addition of 'clearwater' to kill of the odour causing bacteria.
So... finally... cheers for your blog and you tube post!
I am also a planted fishtank keeper and Sam's bacteria problem seems strange to me. Instead of adding something that kills bacteria I'd rather see him add something that establishes a healthy colony of good bacteria. All planted fishtanks have aerobic and anaerobic bacteria living together and healthy tanks do not have an odor. The basin of a greenwall is like a simple pond/fishtank in many ways. I add aquatic snails and worms to my basin to help breakdown plant material and add a natural fertilizer source.
Sam also mentions blocked pipes. I can't stress enough how important it is to include inline filters between your pump and your irrigation tube. Without these filters you will need to check your tubes for clogs like Sam and I. I still haven't retrofitted a filter to my system so I periodically take the top irrigation tube down and clean it out. I also do some spot unclogging with a paper clip. All of which could be avoided with a good filter.
Sam's wall looks amazing and is by far one of the most ambitious walls that was ever inspired by this site. Congratulations Sam!
