Mounted Dendrobium - confused

[Zaskia]

I'm new to orchids in general and ordered a mounted Dendrobium Lindleyi by mistake. I thought it would be in a pot. This is also my very first Dendrobium so I'm still learning about how to tell if it's healthy etc.

If anyone could take a look at the plant and let me know what they think of its condition and if I should do anything specific to it at this point? What about the dead (?) pseudobulbs?

For the watering I watched a few videos etc but I feel a little bit lost. From what I understand I should run water on the roots in the morning, daily, without getting any on the leaves. Or I should put the whole thing in a bucket, plant facing up for about 15 minutes. Is that daily as well? I don't know how some of the plant wouldn't be completely under water this way.. The leaves are so close to the roots.

I have the time to use methods that require more care. I'd just like to do what's best. I also read that they like more humidity and I could mist the plant but again, what about the leaves?

It's about 22/25 degrees celcius in my house this summer and the humidity is around 60%. It's much, much lower in the winter time.

Thank you in advance.
