New to Onc.s Question re S/H

[early]

I have had 3 small onc.s for a month or so. They look healthy, starting to drop blooms. Pbulbs unchanged from when I bought them at a nursery. all NoID yellow (2) and a dainty wine with a bit of white.

I have read somewhere that Onc.s don't like S/H. I gently repotted the first purchase and put it back in s/h. Since I am so new to the tiny frail looking roots compared to Phals, I have no idea how to care for them. One OB person said care is very similar to the Phals, but I never addressed the s/h issue before.
Anyone have Onc.s in S/H? and have some advice

1) ANY plant can be grown in semi-hydroponics.

2) That does not mean any grower can do so, because it is not "the plant" that determines success, it's how the S/H pot environment works with the rest of your growing conditions to provide the needs of the plant.

In my personal experience - growing in a warm greenhouse - oncidium intergeneric hybrids did very well in S/H. (There are none in my collection since relocating and downsizing.)

If you want to be successful with a particular plant in S/H culture, first understand the needs of the plant. Second, understand how the S/H environment affects your overall growing "picture". Third, recognizing that when a plant is moved from a drier root environment to S/H, it will need to replace its entire root system, the smartest thing you can do is wait for the emergence of new roots before repotting it.

Once the plant is established, you can treat all your plants the same as far as watering is concerned, and focus your attention to other cultural factors like light levels and temperature.
