After being a member of this forum several months now an introduction is in order. I’m Chuck Hanson, a name you might recognize if you collected succulent plants. I founded and ran Arid Lands Greenhouses in Tucson, AZ for thirty years and specialized in the sexual propagation of many species of succulent plants. During those thirty years many trips were made to East and South Africa and Madagascar. There were many spectacular orchids seen on these trips so when Arid Lands was sold it was only natural to start over with orchids. As this was a totally new direction the business was named Orchid Renaissance. After several years of growing orchids commercially it seemed time for a total immersion so my wife and I moved to Ecuador, purchased land and built a home next to Ecuagenera’s nursery in the upper Amazon valley, two kilometers west of the charming little town of El Pangui (the name means big boa in the language of the indigenous Shuar indians). After four years my wife felt she was too young to retire so we returned to the US…Nebraska, of all places. At the risk of sounding like Martin Johnson, after four years in Paradise Nebraska seems like Siberia! At least we have a nice greenhouse to house a growing collection of orchids and my wife’s collection of cacti and succulents but, at 24’ X 60’ it is filling at an alarming rate. It is passively cooled, roof vent and thermostatically controlled 4’ side walls, and heated with forced air propane. In the winter there are two humidifiers running 24/7, and the gravel floor is wet down each day. The temperature ranges from a low of 50F to a high of 105F and the RH from 25%-90%, maybe not the ideal orchid house but most species do very well here. Those that don’t are not replaced! An added benefit, to the plants at least, is our well water, drawn from the Oglala Aquifer. Apparently the overuse of fertilizer on the surrounding farm lands has risen the level of nitrates in the water well above the maximum allowable 10ppm. This seems a happy level for orchids so none of the plants has had additional fertilizer for over two year and yet all have healthy, vigorous roots and flower prolifically. The pH is 7.1, perhaps a little high. The collection is primarily dendrobs, rupicolus laelias, bulbos, oeceoclades, and species from hot dry areas such as Australia. Please excuse me for being so long winded. I look forward to the posts on this forum.
