Great new Phal, you'll soon be hooked.
I keep getting tempted by those supermarket Phals as well. Two came from sainsburys not long ago because they were on offer (half price so I had to buy two right?)
I find Phals tend to start a new spike in cooler weather. You might have problems getting them to flower if you heat your house all night in the winter. I only heat the house in the day and the temp drop at night over the winter seems to trigger new flower spikes.
