Elaine...you will die when you hear this....the other day at the Tampa Orchid Club..the guest speaker was Phillip Hamilton... a phalenopsis expert...grower, breeder..judge.. He's originally from Jamaica and grew up growing Phals with his dad. Because it's so hot in Jamaica , it was difficult to get the plants to spike..apparently its a combination of shorter days and cooler temperatures that makes it all happen. He grew up using ice cubes and cold water to get the spikes started.... He now works for one of the major suppliers of Phals to the big box stores and I wonder if that is how the whole thing started?
