They love growing under lights. I have bought many from a seller who grows that way. I adore them but have trouble getting them to bloom. I keep them cool in winter and cut down on water but there's only northern light in there. I plan on using grow lights next year. My exception to difficulty getting them to bloom is L. lucasiana which bloomed all winter (see above) and blooms like a champ every year. And I had L. lundii in the warm room in full sun but it only bloomed for a short time. My L. lundii x epi. bloomed for months in the cool room too. Ursula blooms them warm in her well lit greenhouse much more successfully than I.
