I've moved about half of all my highlander cuttings into the lowland chamber to see how they react in regards to being warm for the rooting/establishing phase. I think the 45*F winter nights are a bit harsh for the cuttings. Only the aristolochioides are showing signs of establishing (the 50% who've made it this far - about 4 weeks) everything else still alive and green seems to be in limbo.
Cool growing orchid divisions/backbulbs establish much faster in warmer temps than they need so I figured I should play with the neps a bit. If it works I will of course move them back into proper highland temps once the roots develop. Anyone else tried rooting your highland cuttings in warmer temps?
