I’ve also heard that hamata isn’t extremely picky about low night temps. I mean they definitely need it...but down to 50? I don’t think that’s needed. I’d try to keep them at your low of 60 if possible and I agree Sumner temps need to come down. But I don’t think it’ll suffer. I keep mine on the warmer side of my tent so it stays about 55-57 at night...instead of 48-52 (didn’t seem to especially like 48 degree nights).

Dropping to 50 F is too low for most standard highland Nepenthes; upper 50's is the necessary range for most, low 60's tolerable but better for intermediates. only ultra-highlanders like really cold conditions regularly.
