As they're in S/H culture, it's not an issue, Bill.

FWIW, I have those same plants, and they delayed blooming until they were
pretty much pot bound.

I've had Miltassias Cairns and Royal Robe for three and four years.
They're
both growing very nicely and crowding their pots, but refuse to bloom.
They're in S/H, in high light, in my intermediate-warm greenhouse with
60%
humidity. I water every 1-2 weeks depending on the season, and fertilize
three out of four waterings with 150 ppm MSU. I have succeeded in
blooming
four or five other Oncids.
Any ideas on how to jump start them?

Hi Tom, Neither of those plants wants to dry out. We water twice A WEEK
!! and you are definitely overfertilizing. Miltassias also like to be
potbound if they are in too big of a pot, you'll have trouble. Hope
this helps, if not go to my website & click on Care. Bill
