Phalaenopsis Mini Mark "holm" care

[Orchid grower]

Hi everyone, I recently purchased two phalaenopsis Mini marks from an orchid show, they came with no media or anything and just the roots. I potted them right away but they aren't doing well and roots keep dying off.

I've tried finding info on care specifically to this plant but I'm actually having a hard time and only links to purchase the plant come up.

But I have read that they prefer to be watered before they fully dry out, is that true?

Would love to hear your experiences and any tips for mini mark.

Thanks
