Re: My GreenHouse Build.
Hi All
Stuart mentioned HOT! This summer has been a challenge. Temps peaked at 117°F , 47°C . Many nights they never dropped under 90°f . Humidity was also higher than normal 30% to 45% so days. This went on for 3 months straight. 6 months ago in anticipation I did try a small evaporation cooler. I lost a few plants after a week to rot. Cooler was tossed. A 18" box fan did nothing to keep the air moving. I installed a 12" fan just above the door and that helped a little. The temps inside still rose above the air temp even with the shade cloth and the fan. I made the mistake of watering plants during the heat wave. I forgot that the roots shut down due to heat. So I lost at least 18 plants due to center rot. I had a few mature mammillaria that turned to a mush overnight. I replaced the 12" fan with an 18" fan that moved 400% more air. I placed the 12" fan low at the door. This made a huge difference in air movement. Temps inside never exceeded out side temps again. I stopped watering anything unless it drooped. The lose of plants almost stopped. The last 6 or so I think were just catching up with hidden damage from before. I have given up trying to grow small to medium size succulents around here. They just can not tolerate the intense heat I lost at least 20 plants. Fortunately temps have dropped. 100°f during the day and down to 72°f overnight. I have slowly started to water again but only at dawn when the plants are alive. Inspite of the heat many thrived and grew.
Here we are in June. And in August A few even flowered in the heat
