As part of the Regional Food and Fuels project with the Santa Fe Alliance, I've been visiting some of the greenhouses in the area to study the potential to grow food year round in commercial quantitites in Northern New Mexico. Some of the setups are downright impressive, but every one I visited needed help. Either the controls don't work properly, or they leak and need lots of supplemental heat to work in cold weather.
I'm wanting to start a Winter Farming Cooperative that enables farmers that want greenhouses to finance them by selling shares of the produce they will grow in them, just like with a CSA. Only I'd like to see dozens of farmers pool their output in solidarity, so the risk and rewards could be spread over a wider base of farms.
Send me an email if you'd like to follow this effort.
