I deflasked the Zygopetalum seedlines on November 12th, and had kept them in a 100% humidity tray since that time. I decided it was time to open them up to the real world, and have started “airing” them for an hour or two at a time — increasing the time each day. I think by Christmastime, I can keep them permanently out of the humidity trays.
They look pretty good. Some have obviously grown.
