boy you sure picked a hard one! I have 3 (about to be 2
) and they are tricky. Lower light when they are young, but increase it when they get in the footlong (?) leafspan. They don't like too much fertilizer, but like a medium that has some alkalinity in it, like limestone. Good air movement, rainwater if possible, and tons of patience! hope that helps.
I am still a beginner by FAR when it comes to these, but there is a wealth of information on slipper orchid forums especially.
