Back in late June I was at the local Walmart and they still had a lot of Mothers Day orchids sitting inside. Most had already finished blooming and looked like they needed some care. So being adventurous and having room in my greenhouse I asked the manager if I could buy them for 1/2 price or less. I think she was happy to get rid of them and make a little money. So I loaded up 22 of the best ones I could find and brought them home, re-potted and set on the shelves I have. A few days later I noticed that the temperature in the greenhouse was running about 125+ (this is Texas) and the humidity was about 16%. After watching a video on humidity trays I came up with my own. Now even though the temperature outside is running over 100 the temperature at the orchids is running about 99-100 and the humidity is running about 38-45% during the day. I'm sure at night it's higher. And I forgot to mention these are all Phalaenopsis orchids. I've posted photos of my humidity trays which are very easy to make. The large pan is 15 13/16 X 11 5/16 X 2 7/8. Then I found another pan that will fit upside down inside of it and drilled multiple holes through the bottom. This supports the top piece which I found in the BBQ section of the grocery store as well as helps support the pots.
