Is this enough winter light for my cattleyas to bloom?

[Alvaro78]

Hello everyone.
I currently have most of my cattleyas near a really big western facing window and I am worried my cattleyas may not be receiving enough light during this time to actually bloom.

I wanted to know if cattleyas during winter can get between 8-9 hours of sunlight and bloom. I was watching a video from Roger on youtube about his winter care and he had some cattleyas and he said he doesn't supplement them with light during the winter but since he grows them in kind of a greenhouse I was wondering if my case would be similar since I live in Spain and he lives in the UK.
Would them having less light during winter just cause them to slow down but eventually bloom? Some of my cattleyas right now are growing new pseudobulbs and roots and they both keep getting bigger so I have been fertilizing them still to help with the growth so that may be a good sign? Or maybe I will just get leaf growth without flowers?

I hope you can help me with these questions. Everytime I have posted here everyone has been so lovely and helpful

You're at the same latitude as me and I don't have any problems blooming them. Madrid climate is much like mine and a good amout of winter days are sunshine days. Anyway, just wait and if they don't bloom try to find a south window and give them direct sunlight.

Thanks a lot rbarata for the response! I see, honestly most of my cattleyas haven't seemed to stop growing even with the shorter days. When the days are sunny they receive a bit more than an hour of direct sun in the evenings. Do your cattleyas stop growing in winter? Also, do you have some species? And if yes, do some struggle more than others during winter? Thanks again!

I have hybrids and species, also I have a milleri, a briegeri, a Laelia anceps and they all bloom. Note these are all species that need a lot of light to bloom.
Some Catts grow and bloom in winter and all of mine do what they are supposed to do.
Look at the leaves and their color, light green is what you want to see.
You can also use a photometer app and measure the light. But before, ask a favour to a professional photographer and compare the values in your phone with those in his photometer as there's always some discrepancies.
