Oncidium starts from "backbulbs": Update

Today is my day off. I went for physical therapy for my neck disk, now back home. Before starting "homework", I checked the orchids, watered them. I accidentally noticed the baggy-with-sphagnum-backbulb system that was set up 4 months ago. Buy "set up" I mean, I had cut the backbulbs off the original orchid (Oncidium "dancing ladies"-type) , wrapped them in damp sphagnum moss, placed them into a ziplock baggy, zipped it shut, and left them in an east windowsill. I forgot to record when I started this "experiment". I'm thinking September. That would be 4 months ago.

As I discovered the ziplock bag. Barely visible sprout in the baggie. Cool!

Out of the bag. I couldn't resist. Plus, I wanted to re-position the sprout so that it gets more light.

This plant, started from another backbulb at the same time, is further ahead. growth is slow - after all, (1) it's an orchid and (2) it's midwinter and (3) I don't know what I'm doing. Still, it IS growing.

Flowers on the original plant. Photo taken January, 2008. Although the plant isn't in bloom yet this year, the new bud spike is growing mm by mm.

So now the starts are back in baggies, but separate baggies. The sprouted start is in my home office along with the other orchids, still in baggie because roots have not sprouted yet. I think they will come when the new start is bigger, and roots don't grow from the old backbulb.
