Hi Jim! My blooms only lasted about 3 weeks or so. They started just before Christmas if I remember correctly and started wilting sometime mid January. But I also had a change in growing culture....I added a MistKing system to my orchidarium since I wasn't able to keep the humidity above 40-50%. Now it stays around 70% and goes higher sometimes then that, so the culture change could have had an effect on the length my blooms lasted. Others had their blooms last much longer then mine. Hope this helps and good luck at the show!:goodluck:
