I was bitten by the orchid bug about 2 years ago and now have quite a few in my collection.
Problem is my girlfriend tried her hand at a Paph (which I don't own) that died a horrible death.
Since I am constantly checking over mine, I can't tell which species are more tolerant to neglect.
Would you have any species in mind that would thrive in a S-E window and are more tolerant to uneven watering?
