As i was checking my plants recently that we are growing inside drainage pipe I came across an idea that would make a lot of sense for the side of shipping container homes. One of the reasons people get put off with the idea as a home is down to the steel external walls yet if you set up plastic pipe with plants that will hang down or even extend out around 1ft onto a trellis before growing down the trellis you could end up with a natural cooling affect that also may reduce the needs/costs of insulation. Currently I haven’t tried it as the tomato plants we are currently growing are still going up and haven’t started to hang downwards. Their location offers them up to a 6ft drop if they will grow that much as well as in full sunlight which tells me that other plants could be used for the purpose of natural cooling on a shipping container as well as using the trellis space for a cool sitting area as air should flow along inside between the trellis and container wall.
just a thought..
