My first orchid, trouble with roots! (Air roots)

[Vanda lover]

I have a vanda and a rhynchorides growing in vases and I find it one of the easiest ways to grow them. I soak them with half strength fertilizer one a week and mist the roots daily. Another way I grow them is in hanging baskets with lava rock or sphagnum. I mist them daily and soak them about once or twice a week. I like lava rock because it doesn't break down. It's almost the same, but I think the one in the vase looks happy and there is no guess work. Vanda roots tent to be silver when exposed, but in the vase they stay green longer.
