My greenhouse heater stopped working last week and I haven't been able to fix it. I'm ordering a new one, but it most likely won't arrive before I go out of town on the 19th. Most of the neps I have in the greenhouse are intermediates, but I have some lowlanders as well. Temps outside have been in the mid to low forties at night and 60-70 during the day. I'm not sure what the temps inside the greenhouse are, but the roof is double walled polycarbonate, which should provide some insulation. Do you guys think it'll be okay if I leave my lowlanders in the greenhouse?
The plants I'm most concerned about are:
N. x mixta
N. x dyeriana
N. rafflesiana x veitchii
