On a 1 degree night, the temperature at soil level was 19 degrees. <\/li><li>A manual effort is required to lift off the row covers when the sun is shining. This shows in the difference at soil level between 9 and 9:30 am. With the row cover down at 9 am, the row cover was keeping in the night&#8217;s cold even though the temp in the hoophouse was rising quickly. With the row cover raised shortly after 9 am, the temps in the hoophouse and soil level equalized. <\/li><li>After the sun went down, it was 19 outside, 20 in the hoophouse, and 30 at soil level, showing the row covers really retain some of the day&#8217;s heat. <\/li><\/ul>\n\n\n\n<p>Sam wants to automate the lifting of the row covers (and other aspects of this process when we get a greenhouse). But for now, it&#8217;s been an interesting science project and we are still eating a small amount of greens. <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Sam is interested in the temperature management inside the hoophouse where we are overwintering greens.
