humidity???????

Im 1 week into flowering
Im growing in tent for the first time
My humidity is at 75%

Can any 1 tell me if thats ok

no thats not too good, in flowering yu need it to be atleast 40% - 45% max
having humidity higher then 45% in flowering can cause powered mildew or mould

seems a bit too high for me. You better get a dehumidifier or move a lot of air so you don't develop any powdery mildew issues. try to bring it down to 40-55%

That's high, and it's only 1 week in. Needs to be about 30% lower, and then about 40% lower the last couple weeks.

.......................................................put a tray of cat litter in your tent/area and watch your humidity fall

sure, i can tell you that NO, thats not ok. you want 30-40% when flowering.

thanks for replys

ill get small fan for extracting warm air

will that sort it???????????

you taking the piss bout the cat litter or is that genuine

not bein funny...just have to watch wat u beleve

An exchange of air via exhaust would be ideal.

if you dont have a fan extracting air it will help. yes.

when does it hit 75%.........at night? if so, place a seedling mat in tent to maintain day temps, and avoid spike in humidity. Dalton's Law of Partial Pressures, or some shit like that............

getting a fan to blow the moisture out will help somewhat.

Bear in mind your carbon filter will only be working at about 25% efficiency at 75% humidity.
Also bear in mind that humidity meters are notoriously dodgy. I have 2 that I calibrate myself (using the damp salt method, look it up) and they still often read 10% apart.
