I have some Neos in a terrarium (but not a cold one like yours Ron, mine gets regular house temperatures) under T5 HO lights. They didn't get any winter rest this year, partially because they were in bad shape last fall. One of them is currently in spike, and the buds are growing well (fingers crossed) but I just took it outside of the terrarium (but still under T5) so the spike doesn't get soaked by my automated misting system (4 times a day). I don't know if getting the bud sprays might damage them, but I do know that if you spray the flowers once opened they won't last as long.
Naturally they bloom mostly at a time of the year when temperatures are above 20º C (in the 70s ºF) with night temps above 15º C (in the 50s ºF), I don't know what temps you have in your cold tank, but maybe they got a bit cold?
Hopefully for you the plant will start growing and get ready for next bloom by the end of the summer
