If you want to have a Vanda an Ascocenda is usually a better choice. They are smaller and grow and bloom in a lower light and temperature range than Vandas. There are some very nice colors to get. This was an impulse buy at POE. It was late and I still had money. It has bloomed every year in the greenhouse.

The Sonoma greenhouse is about a 15 minute drive from where I live. In warm weather I go there every day to water the Vandaceous plants and some of the other plants. I tend to get there between 10 and 11 in the morning and am always gone by noon. This pattern caused me to miss seeing a problem.

The greenhouse should regulate the temperature, keeping the top temperature in the low 90s. There are vents that open, a vent fan, under bench misters and two AC units. I was seeing plant stress that I was thinking was due to the increased light this year. I got tunnel vision trying to adjust shade cloth but the problem continued.

A few days ago we had a particularly hot day and I got there to water later than usual. I was shocked to see the interior temperature at 105 degrees and the AC not on. I had to replace the thermostat and got the AC back on track; it comes on at about 95.
