C. tigrina : Did I just kill it?

[Optimist]

I had the day off so I decided to re-pot a few plants, a Dendrobium abarrans and a C. tigrina . Mostly because I got them as seedlings and they had been in pots for a year. The abarrans had a bit of black fungal spots.

Everything went well with the repotting until... .

I realized I did not know that the Bifoliates are easy to kill if you do not pot them at the right time. I decided to watch some youtube videos (after committing the crime, of course) and thought "gulp-- I just murdered my tigrina !!!!"

So, one video, Stephen Van-Kampen Lewis (who has a channel and seems to know the bifoliates well) had a scene about the correct time to re-pot tigrina . He said that you should repot when the new root tips are just showing out of the base of the P-bulb, but you have waited too long if it is too long (he showed 1/2 to an inch of root). So, I looked at my base, and saw that I had a tiny root or two coming out of the latest new growth (see picture). So I think I jumped the shark on that one. I just happened to stumble into the perfect time to repot.

So this is the second repotting of a seedling of C. tigrina 'Voodoo Child' X 'Summer Voodoo". It is actually growing remarkably fast. It's about 7" tall now. I hear it gets about 3 feet tall. Does anyone know when "blooming size happens? On Youtube and in pictures it looks like about 16 to 18 inches.
