Cattleya Growth Triggers

[mopwr]

Thanks for all the replies - I never really thought if there was a specific trigger to start new growth until recently when I realized the other two seemed to be just "sitting there" as it were. I grow in a larger terrarium, under lights, and can control light intensity, humidity levels, and temps so I'm going to increase the light duration as a starting point (maybe the intensity, just a bit) to see if that does anything - per Stephen, I may also bump up the watering a bit more. As far as the roots go, one of them (the aurea) was going so nuts, that I had to slip the root ball out of the pot, moss and all (how it came from Miranda orchids), mvoed it to a bigger pot, and packed some bark around it last fall; since then, it's now packed that pot with roots and started to crawl out of that one too - may post a pic later to demonstrate what I'm talking about.
