   Hi Greg, I was at the Cattleya Symposium in Florida last weekend and asked Roy Tokunaga from H&R Orchids your question. Roy was not familiar with the product. He gave a talk on Flower Boosters. I don’t know if you are familiar with H&R but they are a nursery in Hawaii that grows a beautiful, clean plant. Roy, in my opinion, is the most knowledgeable grower I know of. Roy said there is very little scientific research on orchids. So there are myths out there people take as fact. “Best growers know how to balance their light,temperature and plant type with a small amount of fertilizer.” He recommends having your water tested. There is an article on the St. Augustine Orchid Society web site by Dr. Bill Argo. Roy said we should use low phosphorus fertilizer. High amounts of phosphorus have been shown to produce a 20 % reduction in blooms. Flushing with water once a week is important. And Roy has seen an increase in blooms using micronutrients like STEM by Peters or Microcomplex by Millers Chemical. Hope this helps. Carol

   Hi Greg, Let me ask a few people. What genera of orchid are you growing?
