29.12.14: I had a discussion with someone who said that my vertical farm bottles should be opaque and not of translucent material. The roots do not like light, and will not grow correctly out to the edges. Also in hot conditions the bottles could dry out too quickly with solar gain. So, one by one, I am covering them with reflective aluminium tape.

16.12.14: I have added a frameless polycarbonate front porch to my house. This is recycling some 6mm polycarbonate from an unfinished solar panel building project. Because it is curved in a vault shape, it can be completely frameless and will withstand gravity force and upward wind loads.
Subsequently, after a few gales, it became obvious that some bracings were required, and some metal bracings have been added, but the appearance of the porch remains extremely lightweight.

1st December 2014: These photos show the process of building the vertical revolving barrel farm.
See some comments by John Macdonald about my vertical revolving barrel farm project.
The design of this is based on the Garden Tower project from Michigan, but their product is not sold outside the US and Canada. I would willingly pay the full price to buy their product if they would make it available in the UK. I have based the construction on their design idea which is to have a strawberry planter style outside surface with 30 pockets, then the centre filled with soil, and the centre line with a 150mm flue filled with kitchen waste and worms. At the base there is a collecting chamber for crumbly compost and a another collecting chamber for liquid produced by the worms. The construction starts with a B and Q 210 L water butt.
Building one of these in December is not likely to produce massively good results until next spring. However, I have tried planting it with some Pak Choy, Kale, and Rocket, all of which are capable of growing in the cold weather. The idea of the revolving system is to allow the plants to get a fair share of sunlight, and to allow me to stand on the concrete doing maintenance instead of walking round the barrel on the grass.
