Umm is it male or female ? When should it open ?
I did just remove the water from the bottom of my tank so no heat,
but the tank only dropped 2 degree daytime but more of a nightly drop of 10 degrees.
I think the nep should be okay(will flower fine).
My neps that were wasting away on my windowsill of torture are in the tank the rest are in the closet,
it's basically an almost all nep tank It's true that the longer you grow the nepier you get!
If your wondering about the multipotted nep I sorta ran out of room,
the nep was in bad shape(arrived with no roots) so I stuck it in there when it gets better I'll pot it up.
Sorry about the screwup on the title
