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 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.
