I usually grow them in pots. Then they sometimes grow out of the pots and mount themselves to the benches and trays. I unmount them, divide them or just tear off the old depleted pbulbs and repot them.
The roots need lots of space and air, so good drainage and a very loose potting mix is essential. Mounting or basketing works well also. When drainage needs are met, plants appreciate frequent waterings, as long as the roots dry out a little between waterings. As long as plants are active, they can take regular mild feedings.
Bright light and warm temps work well. Intermediate winter temps are ok.
Thanks everyone. The lip is actually more brilliant than it looks in the photo. The combination of the magenta lip and the brilliant sunlight were causing flareups when I was taking the photo. I overcompensated and made the lip look a little washed out. Sometimes the low angle afternoon sun gives me problems.
