I have a couple of phals spiking also and I was very surprised because my phals have never spiked before the first cold spell hits South Florida. This is at least a month earlier than they've spiked before. Maybe it has something to do with the end of the world coming later this year (2012).
Well mine that were spiking in my comment earlier in the thread are now flowering and MORE of them are spiking now. I seem to be having a good year for phal spikes
