Building a cost effective walk–in cooler

Skip Paul with CoolBot at Wishing Stone Farm

Skip Paul with his latest CoolBot at Wishing Stone Farm

Over 18,000 CoolBots use standard window air conditioners to turn super-insulated rooms into walk-in coolers. Farmers, florists, breweries, wineries, pubs, caterers, restaurants and grocery stores use CoolBots.

CoolBot cooler systems cost significantly less up front than conventional compressor-cooled walk-in refrigerators or coolers. Conventional coolers use more electricity, have higher repair bills and tend to dry out greens and vegetables.

Anyone can build a super-insulated room. Learn how and read more about CoolBots here.

Advanced Growers Workshop

Will BonsallAuthor and grower, Will Bonsall will lead a workshop called “Getting more food from less space & Cultivated crops that don’t need cultivation” on Sunday, November 9 at 1 p.m. Learn about intensive growing and nurturing unusual shrubs and trees. This workshop is open to the public and will be held at the Watson Institute at Brown University in Providence, RI.

Will Bonsall of the Scatterseed Project, will describe a “System” (as opposed to a single crop) of growing a number of specialty crops in less space, using a combination of companion cropping and intensive spacing. This is Will’s version of the John Jeavons Bio-Intensive, non-raised beds. Will has farmed with these techniques for many years, fine-tuning as needed. His practices work for most crops, but especially for compact vegetables.

Will Bonsall will also discuss his less common permacrops including hazelnuts, hardy kiwis, medlars, elderberries and blackberries. He will focus on strategies for growing and processing these permacrops.
