RBR News | April 27, 2017

Posted in Ranch Report

Last summer, we designed and constructed a new passive solar seed “start” house to improve seedling preparation for the growing season. Several of the structure’s energy efficient features were made possible with a generous grant from the Community Office for Resource Efficiency (CORE). Construction was not completed until late in the summer, so this is the first full season that we have put it to use and we have grown more vegetables this winter and spring than ever before.
