Gur (Cattleya) skinneri - back bulb divisions

[Fairorchids]

I have two mature plants (alba 'Cherokee' FCC/AOS & standard 'Waldor' AM/AOS). I have three other clones:

Semi-alba var. Occulata
Alba 'Kensington's Angel'
Alba 'Debbie' FCC/AOS

The first two were purchased as established BB plants in October 2013, small, but approaching BS. Both are busting double new growths this spring.

The last one I got as a single BB in April 2013, with about 2" of live root. I put it in pure spaghnum in a 3" pot. It quickly set a new groth (1" bulb), which grew another bulb (4") over the winter. Now this one is also busting a double new growth (plant on the right).

I guess it is something in the water.
