How might I build an indoor living wall? Answered

I was thinking about the research that was done regarding improving indoor air quality, and one idea piqued my curiosity, and that was the concept of a "green wall" also known as a "living wall."

I'm wondering what the feasability of such a thing would be for a residential home, using items that are either recycled or easily obtained from say a hardware store. I am aware of being able to purchase setups, but they cost a fair bit of money and I thought it might be more interesting if I might construct one myself.


 Hi there - Garden Beet sells Woolly Wally Pockets which are made from recycled plastic - promote plant growth and easy to install.

Very affordable when compared to other green wall systems


Building an active wall seems impractical for indoors. Building a passive wall seems feasible assuming you have enough light. I once saw a wall mounted strawberry planting system where pots were mounted at a 45deg angle. It was mounted out side a nd could be watered just by aiming a house at it. For indoors if you mounted water tight troughs on to some plywood and set the pots in them you could put a piece of cloth hanging out of the bottom of each pot that would wick up the water in the trough into what ever planting medium you use. The pots are removable so you can perform maintenance on the system or on individual plants. You could set up a pump on a timer to water the system. Drainage holes could be made to make sure not too much water is put into the troughs.

Check out the work of Patrick Blanc. You can get the general idea here: http://www.worldchanging.com/archives/005734.html

basically, it's a metal support frame with a 1cm plastic layer attached, then 2 layers of felt, between which the plants take root and are watered through capillary action. You might be able to substitute some other materials for some of these parts.

even vertical walls have at least 'some' terracing or shelving to hold the plants. You need a location with plenty of light - or your wall won't flourish. More light = more photosynthesis = more air filtering :D
