Build a $300 underground greenhouse for year-round gardening
Growers in colder climates often utilize various approaches to extend the growing season or to give their crops a boost, whether it’s coldframes, hoop houses or greenhouses.
Greenhouses are usually glazed structures, but are typically expensive to construct and heat throughout the winter. A much more affordable and effective alternative to glass greenhouses is the walipini (an Aymara Indian word for a “place of warmth”), also known as an underground or pit greenhouse. First developed over 20 years ago for the cold mountainous regions of South America, this method allows growers to maintain a productive garden year-round, even in the coldest of climates.[…]

DIY bamboo+hemp bike frame
I saw a picture of a bamboo bike and decided I had to have one. I found out that professionally built bamboo frames cost a few thousand dollars so I decided to build one myself. I had a lot of fun and I hope that you can make one too by following these instructions.
The bike I made is a track bike for commuting to work. The bicycle was inspired by Craig Calfee who makes much nicer bamboo bikes. I really wanted something with a minimum of fancy technology and carbon fiber (although I sprang for the carbon fork). I used epoxy and hemp fibers on all the joints (no pun intended). The track bike also makes it easy in that it is a very simple bike - no gears, cable routings, rear brake or derailers.
Three Sisters
According to Iroquois legend, corn, beans, and squash are three inseparable sisters who only grow and thrive together. This tradition of interplanting corn, beans and squash in the same mounds, widespread among Native American farming societies, is a sophisticated, sustainable system that provided long-term soil fertility and a healthy diet to generations.
Corn provides a natural pole for bean vines to climb. Beans fix nitrogen on their roots, improving the overall fertility of the plot by providing nitrogen to the following years corn. Bean vines also help stabilize the corn plants, making them less vulnerable to blowing over in the wind. Shallow-rooted squash vines become a living mulch, shading emerging weeds and preventing soil moisture from evaporating, thereby improving the overall crops chances of survival in dry years. Spiny squash plants also help discourage predators from approaching the corn and beans. The large amount of crop residue from this planting combination can be incorporated back into the soil at the end of the season, to build up the organic matter and improve its structure.
