would 70% humidity be too high for flowering?

if properly ventilated?

Mold will be an issue with certain strains. If you can prohibit mold from growing at 70% humidity, there is nothing about that humidity level that will hurt your plants.

70% humidity is going to give you mold problems. If your room is properly ventilated it shouldn't get that high. 55% is about the highest you would shoot for.

waaay to high to flower anything but tropical sativas, or sativa dom. mold resistent strains

this the second thread he made asking the same shit... hahaha.. im not sure the answer he looking for

yeah i agree with the possible mold problem and or some budrot around week 6 or 7 of flowering.

lol

I have 80% humidity during summer months. Never any problems. Lucky I guess

Not true, if the air you are intaking is very high humidity then no mater how much airflow you have it will be high. I know as thats the problem im having. Plenty of air in and out and loads of oscillating fans blowing but the air at the intake is 80-100% so I cant get my humidity below 70-75%

i bring in outside air for ventilation and if the outside is high humidity, then so will the room. during lights on, the ventilation is on all the time. when lights off, i have options of either a timer, thermostat control or both at the same time. i usually go with the timer funtion and have the vent come on twice for 15 minutes during dark. i will also run the dehumidifier while lights are off.

even with the dehumidifier on at 35% or 40% humidity for 12 hours i have still had problems with certain strains. a couple years ago was a white rhino. i had bud rot on the top. the mother got it on round 1 and the clone did the same thing on round 2. all other plants were fine.

this time around was the blue hash plant. same as above for both rounds.

there is no way i can run the dehumidifier during lights on due to high temps.
