Ive got several droseras and im pretty new to growing them. Ive been keeping them in a terrarium under a light in a 78-82 degree room and they did seem to be doing pretty well. What I have is d. capensis, d. adelae, d. burmannii, d. madagascariensis, and d. binata. The binata and capensis and the madagascariensis looked like it was doing very good, putting up new leaves and everything but the ends of the old leaves and the the new ones are dying off. The adelae is doing the best out of them all, seems to be growing fast. Is there somewhere else I can grow the ones that are not doing too well, maybe a windowsill? Would any of these grow outside year round here in east TN, zone 7?
