What are the poles with bottles for?
They are not poles, but hollow PCV pipe (from a broken soccer net a neighborhood kid gave me) which is pushed into the (wet) ground, into which water goes in order to get it closer to the roots, rather than evaporating on the top soil. The bottles fit (and hot glued) into the pipe so as to hold more water.
And since it cost the landlord over $400.00 a month for water, in the back of the garden are 64 gal trash barrels filled with rain from the roof (via a tarp system since the center drain that flat roofs usually have does not work or something, and there is no gutter). The barrels are covered with mosquito netting.
And I have a cheap 12v DC, 110GPH pump, powered by a 12v computer power supply, which pump I plan to connect to a long length of some old hose, plugged at the end but with different size holes in the holes which will be routed to the plants, and so the water can pumped to the plants. A work in progress.
Thank God for what we can do, and for rain. It took Noah 120 years to get the Ark done, but this project is nothing like that size (plus the city will not let us even have a cow)!
