Dont believe all you read, phals do not need lower temp to initiate flower spikes. In fact my experiments have demonstrated that light intensity change initiates spiking in phals.
Species cats are generally seasonal flowerers and obviously spring flowerers wouldnt be initiated by a drop in temp, probably daylight length in this case. With hybrids the genes have been mixed so we now have cats that grow and flower with no regard to the season. So it really depends on the parents.
