Photoperiod and Cattleya walkeriana blooming

[rockyfarm]

I've seen lots of information about natural conditions where C. walkeriana occurs, and much advice on its cultivation. Typically, it is suggested that it have seasonally adjusted photoperiod, temperature regime, and watering frequency. However, several under-light growers apparently have frequent and abundant blooming under year round ~14 hour/day lighting, with some reduced watering only during the plant's after growth rest period. I have no doubt photoperiod change controls blooming in many plants but our grow rooms would be more effective if it could be ignored. Can any members inform us of routine success blooming C. walkeriana under lights, with no seasonal change in duration?
