| Cambria is actually a registered grex name for a Vuylstekeara, which is an intergenerig hybrid of the oncidium alliance. The European market was flooded in the last decade with mericlones of Vuyl. Cambria 'Plush' AM/AOS FCC/RHS and the term "cambria" sortof became a trade name for any Oncidium intergeneric hybrid.
As for lights, my wardian case has 8 4' tubes burning on a timer, currently, and I'll probably be increasing that number to ten or 12 in January. As far as growing under lights is concerned, the more the better, so long as you aren't causing serious temperature issues. My wardian case is designed to bloom higher-light cool growers. If you plan to bloom anything other than Phals and Paphs, I would definitely go for at least 4 or 6 tubes in your setup.
