Negative temp DIF during Night Time...

So I have a sealed room running on a split ac with no exhaust.....At night the dehumidifier heats the room to a -5 DIF night time temp.....so my daytime temps are 84-86 deg and my night time temps are 87-90 deg....As I understand having the negative DIF shortens elongation.....I don't have an exhaust and don't wanna run ac during night time.....Was wondering if anyone has run a negative DIF throughout entire flowering cycle??...
