Backyard Mars Garden Greenhouse Tests 2 November, 2001  Typical cloudy Oregon Fall day. Wet outside, high humidity inside the Greenhouse. All three of these runs were done for 23 hours. Started the sessions at 7:00 am and ran to 6:00 am the following morning. The humidity goes down when the temp goes up. Because the air can hold more water when it is warmer. As them temperature drops, the air's ability to hold water decreases, causing it to condence out on the insides of the greenhouse. The Mars Garden is approximately two meters by two meters and three meters high at the back. 5 November, 2001  Sunny with some clouds. Note how the humidity mirrors the temperature. Variations in the high readings are where the sun went behind some trees in the neighbor's backyard. 6 November, 2001  A sunny and bright day. But crisp and cold. Spikes at the 12th hour is when I was in the greenhouse doing some minor work around 7:00 pm. The small temperature drop between the two spikes are when I removed one of the greenhouse panels prior to reattaching it. Most important, note how the temperature drops when the sun goes down in each of these runs. At this point, the greenhouse has no insulation. I will do another series of runs once I get it insulated. |
