Need care tips! Onc. Space Mine Red Rendezvous and Onc. Rex's Luck Firefly

[sweetas647]

Hi all!

I just purchased two young (2-3 years old?) Oncidium hybrids - Space Mine Red Rendezvous and Rex's Luck Firefly. I'm super excited about them but want to be sure I'm giving them what they need - especially with them being so little!

They are currently potted in bark chips with a sponge/bit of foam around the roots. Each has one very small and pretty wrinkled pseudobulb. I've watered them the past two days I've had them with distilled water and they are sitting in a south facing window.

Does that sound right? Should I fertilize them? What humidity do they like?

Any insight is much appreciated!!
