Culture Lc Canhamiana v coerulea ‘Cobalt’

To my knowledge the other part is C. mossiae. and flower development of mossiae depends on a variation in daylength. So I would shorten the artificial light in wintertime for 2-3 hours compared to summer, and give it a rest period.

Ahh, I have not given it a rest period, and I did forget to knock back from my 16 hours last winter. I'll try 14. What month do you make the change? Nov? (I'm in Canada)
Thanks to everyone for responding. I truly appreciate your input!

This is very important.

One of the owners of H&R Orchids recommends dropping daylength in winter down to 10 hours. Works for me.

I shorten my daylength by a half hour ever 2 or 3 weeks until I get to 10 hours and started doing this yesterday.
