Cattleya labiata under grow lights. Need shortening of "daylight" hours?

[Jeff214]

Hi,

I was reading on Chadwick and sons orchids page (and posts here on this forum) that Cattleya labiata blooms in response to shortening of daylight... and therefore, tends to bloom in the fall (in the northern hemisphere).

I'm growing a few Cattleya labiata (along with C. luddemaniana and C. warscewiczii) indoors under a grow light. I can change the hours that they're on... but it's a bit of a hassle (buy a timer I guess). I was wondering if anyone's had any experience growing Cattleya labiata under grow lights - and if you've had success flowering without changes in "daylight" hours.

Thanks.
