A lot of folks prescribe to the 60° limit, but if they're not too soggy, low
50's are OK for a short time.

Hi all:

I would like to know what is the minimum temperature a phal can withstand
without having it to shed leaves or in any way become retarded so as not
to
flower in its next regular flowering season. I just moved down to
florida,
and have an unheated greenhouse. i heard about the sudden freezes that
occur
in the winter here in florida, and was wondering what would be the best
way
to protect my orchids.. a majority of them phals and other warm growing
vandaeceous orchids from the cold chill(s).

Thanks and replies will be appreciated.

Dada
