Fogponics— a more advanced application of aeroponics where vaporized water is used to transfer nutrients and oxygen to enclosed, suspended plant roots — is where German design companyVakant Designbegins instead with Fogger, a unit designed to give plants that extra boost.
This film tells the story of a South Los Angeles edible garden planted in a surprising spot. Ron Finley, its planter, constructed the garden the way he wishes his neighborhood could be. And his vision of repurposing unused open space, like that of many others working together on urban agriculture in our city, should inspire us all, and remind us of how, with a little creativity of vision, and willingness to get our hands dirty, we can remake spaces defined by asphalt and dead grass into productive places of beauty.
Portland Japanese Garden | Portland, OR | Takuma Tono
Proclaimed by Nobuo Matsunago, the former Ambassador of Japan to the United States, as “the most beautiful and authentic Japanese garden in the world outside of Japan,” the Portland Japanese Garden is a 5.5-acre haven of tranquility and beauty nestled in the West Hills of Portland.
We’ve been inspired by Fan Sheng-chih Shu. His writings from the first century BC describe a method of irrigation where a unglazed clay pot is buried in the soil. When filled with water, the clay pot turns into an amazing high-tech device. The micro-pores of the clay pot allows water to seep into the surrounding soil. A key characteristic is that the water seepage is regulated by the water needs of any nearby plant. When the plant’s water demands have been fulfilled and the soil is moist, the water seepage from the clay pot will stop. When the soil becomes dry, water seepage will begin again. This seepage is controlled by soil moisture tension. It’s automatic irrigation without timers or electronic sensors!
The link above give instructions to build an Olla Irrigator out of two clay pots. They also provide some notes on how to automatically fill the Ollas using a gravity feed.
The rest of their site is also quite interesting. They have a number of ideas for making self-watering planters out of buckets and other readily available materials, including methods to automate filling of the self-watering planter reservoirs.
I have seen the buried clay pot idea mentioned in a Bill Mollison video of permaculture in dry lands on Youtube (it could be this one).
