Hello Raghu,
If you click on the Home section (to the left) and scroll down you will find the culture sheet for Phalaenopsis.
They are rather general instructions, but very helpful still. I love growing them and find they are the easiest orchid for me to grow and I have them throughout my house. I keep them under medium light, never direct sun, I generally soak the roots, then let "almost" completely dry but never dry out. I mist the leaves often, and talking to them is a must in my house
Good luck! .... kiki-do
