hi bruce,
thanks for guiding me so much,for the medium i have used charcoal and coconut husk only,and at the botttom sum earthern chips to balance the plant to stand straight. but when i water the plants all water drains completely,or should the water stand for a little while. all my pots have good hole and even for the vadnas.
the plant is kept seperatley in different basket.i will send few more pic of my vandas ,and can i use the same potting medium for vandas too.should i place the medium inside the small basket or just in the plastic like other pots.
