Today, I had to replant all my orchid flask babies. I learned that the aluminum baking trays I was usng for pots, when put in water on leca do not last… do not know what causes it, but the bottom is entirely “eroded”. Then of course, the moss is wicking up too much water. So now, they are all moved into plastic containers (tupperware) instead. I put a layer of leca in the bottom and then moss.
Here you see Dendrobium cyanocentrum orchids and Cattleya schilleriana orchid babies in great shape. You learn something new every day with this project.
Added: Learned tonight that aparently aluminum react with coppar, iron and chlorine in the water, concentrated traces collects on the surface of the leca. (thanks letherneck)
