Aloha Gardeners,
I'm wondering what the effects would be on orchids using different types of fertilizers. I'm faced with the choices of high nitrate, ammoniacle or urea nitrogen sources. I want to grow show quality flowers on plants that will be in a greenhouse in Hawaii. I've also her mixed reviews on high phosphorus and high potassium fertilizers. what do you think would serve me best? Aloha, Glen
