is it important to have a temp drop with lights off? +rep

im now flowering and i have bought a 20L a day dehumidifier (which seems to only be pulling out 7 litres a day when running 24 hours)

lights on temp - 70-80 humidity - 40-50
lights off temp - 70-75 humidity - 40-55 (using a radiater to keep the temp here so my humidity doesnt go over 50%

my question is - is it important to have a -10 temp drop with lights off? or does it not matter? i heard a few times the ideal temps with lights off is 65 so i wanted to check others opinion as i dont want to loose any yield (but also do not want higher humidity and budrot >< )

There is always an optimum for everything but than there's keeping it simple, your OK with what your running a little cooler would be nice but hay your not stressing your plants so it's all good. Keep good air movement and you should not have any bud rot and drop the humidity in the last week.

thanks for reply, i will struggle to get the humidity down anymore, well i could just keep the tent fully open i suppose

yeah i have my extractor and 2x fans on 24 hours so the air movement is good
