Help with Seasonal Changes

[Becca]

Well so far my 'chids just love their new home in the Orchidarium! I can't believe the new growth I have on all of them! It is so exciting! I know that winter is coming around and most of my 'chids are either later winter to spring bloomers.....so...what is the recommendation for the amount or time of lighting? I have gotten mixed opinions...anywhere from 14 to 10 hours of light for the fall. And what about winter? Is the temperature okay to drop as well? Temps are about 5 degree's cooler during the day now...I would say they are around 75 during the day and upper 60's at night. Will this be enough of a temperature drop to help initiate spiking? And what about fertilizing? Do I need to make changes with that as well? I just got a RO system and I am about to change to MSU fertilizer....is that fine to use year round? So many questions...sorry! This is my first fall and winter with the kids....last year I only had one and didn't pay much attention to it then. TIA!
