Vanda coerulea

[edwardwang]

After several unhappy experiences, I learned that my humidity is too low for vanda. My enviroment is open and away from ground. Wind always belows the humidity away, so I desided to grow all the vanda in pots, and put them above a big shallow tank about 5 cm. This tank is filled with water and small clay balls (Sorry, I don't know the exact English name) to keep the humidity.
This time Vanda coelurea is in good bloom! The roots always show light green.
