ive got a portable air con unit ann, i think they are only a few hundred quid, and it does the job.

Personally i dont like the idea of refridgation units because i think its too much of a shock for the flowers to come straight from the cold and go into someones house which is bound to be much warmer.

I know the wholesalers use them, but going from there and into our shops in the winter the temperature probably isnt that much different, unless youve got heating on all the time.

i like to keep my flowers cool, but not cold.
