High temp vs. high humidity tradeoff

Hey all I am on my second grow now going on my 3rd week of flowering. I live next to the beach making my spot have a RH around 60%, which caused overwatering problems on my first grow (soil would sometimes take a week to dry out even with 24/7 ventilation).

400w HPS in a 5'x5'x8' tent. True OG, White Berry, and White Widow.

With my exhaust on full during daytime it keeps it at 85 degrees and 45-55% RH. Nighttime is 76 degrees getting towards 70% RH.

I threw a dehumidifier in the tent which can keep the humidity down around 45%, however my daytime temp is already very high and it increases it to 90 degrees, so this is not possible without running my AC too (found out the hard way that shit gets expensive real quick). Nighttime with the dehumidifier is around 80 degrees.

Obviously I would like to maximize the quality of my yield at the lowest electricity cost, but it looks like I have to choose between high humidity or high temps. The only other thing I found is buying de-humidity strips that absorb moisture. What is going to be the best conditions? Or could I possibly get away with the high humidity until buds start to form?

I would run the dehumidifier at night to keep under 50% RH after week 5 of flower, most strains can handle 85 degree days.

my plants live in around 32-34 never a issue so i would go high temps over humidity

The only thing you have to worry about with high humidity is mold on ur buds.. Keep an eye on ur buds .. Good luck

thanx for the help guys ill keep my eyes peeled looks like they are doin ok with the heat so far

if you can add co2, supposedly it will help with the high temps.

if you have humidity issues, fans will help a whole lot.
