Den. trinervium and Den. alexandrae Care?

[OrchidMom424]

Hi everyone!

I just got a den. trinervium x sib and a den. alexandrae at a local orchid show. I Love dendrobiums and I am so excited! But I am having difficultly finding information about their care/culture. Can anyone give me any information about the kind of light, temperature, and water they like? How often should I water and fertilize each one? what about humidity? The den. trinervium x sib is in bark in a 2 in. square pot; the den. alexandrae is in bark in a basket that is set in a pot approximately 1.5 in. square (I think it may need a little bit more bark...). I’m attaching pictures!

Any and all help/information will be very much appreciated!! Thank you so much!! 😁
