3 Novice Questions About New Phalaenopsis

[HiOrcDen]

Hi all! This is my first post. We just bought a few Phalaenopsis plants today. I am a relative novice with orchids. I have three questions I need clarification on to get started with them...

First, I noticed that the plants' leaves are tilted somewhat, and I'm thinking its towards the angle where they were receiving sun. Should I set the plants at the same angle to the sun, as I gather this might keep buds from dropping, and boost flowering? Please let me know if my conjecture is right!

Second, what is the ideal range for light level, in foot-candles, for Phalaenopsis? And is it truly best to be towards the upper part of the range, for flowering?

Third, what are keepers' thoughts on light meter apps for the smartphone, and would anyone recommend one in particular?

Thanks in advance
