Growing taller catts under lights?

[dshallpost]

Just following up -- I bought two larger cattleyas -- a Makai Louise and a LC Roebling Beechview. They are about 24 inches tall when blooming. I have had them since last summer and they just finished blooming. I have four fixtures with the lights at varying distances from the trays, to accommodate different heights. So, you can definitely flower larger cattleyas under lights.
