I'm hoping that both my collection space AND collection can expand so when I see specimens I want like the now Restrepia Antennifera, I can accommodate them! It's why I wanted to build a terrarium and now I've filled it I want more.

It's probably a problem

It's a fact of life... no matter how much space you allocate - whether a terrarium or a greenhouse (of any size) or a whole back yard, it WILL fill up. Then you get creative so that there is always room for one more orchid.:biggrin:

Well I had a birthday and was gifted many orchids I wanted to grow... So it filled up very quickly so now I may need another to home new varieties.

Or my Cymbidium will just continue to grow and suffocate me, whichever comes first.
