Julia, all I can think of is perhaps your plant is staying dry too long between waterings. have been growing Phal. lindenii for abut 5 years now. It resides on my living room window sill which faces southeast. The window is a low e, double paned affair, which doesn't allow appreciable heat to pass through. Lindenii is the only Phalaenopsis species I grow there but I have about five different Phal hybrids which share that window. I use no shading but the direct rays of the sun are diluted somewhat by the coppery tint afforded by the material between the panes. On the hottest days, the leaves do not feel warm, but the climate here on the southern Oregon coast is pretty mild.The lindenii is growing in a 4 in. plastic pot in medium bark with a small amount of coarse perlite added. I try not to let the mix get dry and hence water every second or third day.The plant has five leaves and none have been lost yet. An offset is developing at the base of the plant which blooms regularly every year about this time and in fact this year's inflorescence is about an inch long right now. I repot every other year. With frequent watering, the mix breaks down fairly rapidly.
