I'm with @goldenoakfarm on "looping the pothos" I've had lots of them over the years, they just keep getting leggier and leggier.
I'll cut them, what's in the pot sprouts out newer, thicker healthier stems and leaves, the cuttings will root anywhere just about.
I love all your plants @phoenixwren.
This is on my little 'deck' and it has been a real adventure getting things working.
Most of the time, I have two halogen lights, pointed down just for heat at night or when it is below freezing I have a small ceramic heater in there.
Your dragon trees are so tall! Mine are very bendy because of the light. They go hard sideways. :)
Are your plants enjoying their greenhouse?
I imagine they would prefer it being warm enough to sit outside without it but they, like the pothos, get too leggy and need cutting back to improve and propagate.
It is that time once more
