Winter Light Question
I have a greenhouse that is situated in a way to where during the summer months it is protected from the harsh late afternoon sun. Come Nov I removed the shade cloth and tested the light to have an idea how bright the light is. I tested around 11am-12pm and I was getting around 6000+FC from the top of my benches.
Now because the photo-period was still rather long here in Maryland I decided to still keep my orchids and other shade loving plants on the bottom shelf of my bench system where they were receiving from 1000-2000 FC. They are doing well, bloomed and sending out shoots.
Would it be safe to move the Orchids to the top of the bench now? I have not tested the light but I'm getting around 5-6 hours of direct light which I believe will still be in the 5000-6000 FC range.
What do you greenhouse growers do during the winter months when the photo-period is shortening?
Here is my current collection:
*Bc. Angel Lace
*Sand. Black Start Pacific Red Star
*Mtssa. Fitch 'lzum'
*Unlabled Intergeneric Oncidinae
*Unlabled Paphiopedilum
