For me, I water every once and a week and they seem fine, just when you water them, make sure that no water is in the crown, that's how I killed my first one. I grow in about 63-68 at winter so they'll spike, and in the summer the house is 68-74. I think Phal. are the easiest for ME, I envy the Vanda and catt pros...
Mine spike once or twice a year. The only bad thing is my spikes tend to get longtail mealybugs.
I have them because I once had a lily pond in the house. But then I forgot to change the water for 3 weeks and the larvae hatched, that when my HUGE mealybug invasion started. After 3 years, I still have them But I can get rid of them for a while
Good Luck to you guys!
