10 to 20 days of climatic treatment on phals initiate flowering. What is needed is a 10 - 12 celcius lower night
temperature. Here average temp from Oct to March is
30 day and 27 night and I am getting year after year nearer on target for Valentines day! Just have to move in the phal at the right moment inside aircon room at night and move back to gh in the morning. But beware aircon
dries the air ... have sufficient water in trays under the pots.
