and welcome!
Beallara Marfitch 'Howard's Dream is a oncidium intergenetic that is very easy to grow.
Likes light and it can take mild but direct morning sun on an east facing window sill will provide enough light intensity for flowering.
A west-facing exposure will work if you make sure the leaves don't feel hot to the touch. In a greenhouse, 50% shade. I water mine once a week and fertilized every 3rd watering.
Temps can range between 58ºF low (at night in winter) and 83ºF high (daytime in summer).
I hope this helps.
