Hello everyone i need some tips here about my orchid, i have purchased to many Oncidium and Milts species and hybrid and i just cant seem to keep them alive! I live in NY anyone from this area or not could give me some tips, i just cant seem to get the growing media mix right they always rot on me. I have an small indoor greenhouse with grow lights and a humidifier also. Thanks anyone for your help.

I use bamboo skewers in my orchid pots / media to help determine when to water. Miltoniopsis like media to remain a lightly moist, tho not soggy. Moderately bright light.

I have a few oncidiums and one miltoniopsis. I grow in s/h. Except for the burr. Nelly isler I got, all have transitioned easily to s/h. It's easy for me to keep them cool because my office is freezing. I have them in a big east facing window, and it's cold. But the milt I have really took off. It has some wrinkled leaves, but it has a new spike and it never sulked. Maybe try an inorganic medium? I live in Boston, btw, so not too much different from you.

If they are rotting, my thoughts immediately go to keeping them too wet. Media needs to be free draining so it stays damp, but not wet. Also good air movement.
