Someone here, I can't remember how long ago, pointed out that copper wire can be used to slow the growth of algae. In the trays of water and rocks I put on my orchid shelves to increase humidity, algae used to grow quite quickly. A small coil of standard copper wire in each glass tray has greatly

I think Terry misunderstood Peter's comments about the legality of Vietnamese orchids. My understanding is that Peter said that he believed that, according to CITES regulations, any plant that originated directly from Vietnam was illegal. The Antec vietnamense that was sold by them originated i
