Humidity trouble!

I am about 2-3 weeks into flowering and already have baby buds forming. The problem is that the humidity is a bit too high, around 60%. Anything I can do to lower it?

Better air circulation, do you have an exhaust fan in your area? Intake fan? Like suggested in your other post.

Exaust is the best way. You need to get that wet air our of there.

I wouldn't worry about 60%
But if it keeps rising i might use a dehumidifier
it is coming up on cold season most places it usually reduced the humidity

what?? come on stranger if u dont know how to grow dont spread bad information...U should worry about 60% RH during flower cuz thats breeding grounds for powdery mildew..get a dehumidifier ASAP

I only have one fan at the moment, which is currently facing toward the plant. Should I turn it around so its blowing outward?

a fan aint gonna cut it if your at 60% humidity your ganna need a dehumidifier..not a $50 one a $200 one..for the time being get another fan..have one blowing air in directly at the plant and take the other one and have it pushing air out or circulating air

Is there any other way to get the humidity down? I don't have an extra $200 for a dehumidifier at the moment...

Man, that ain't right.
Actuall, not even wrong,,, but definately not absolutely correct either.
Yes, I'm a newbie here. But, I've probably been growing for more than twice your age.

Anyways, where I'm at 90+% relative humidity is definately not uncommon. Anything under 50% is rare. Really. And folks grow all the time without concern of humidity.
While I'll not say it's a old wive's tale,, it's just not totally correct at all.
Pretty much I'm always into the 70's or better about 70% of the time. As of yet (knock on wood) I've never experienced mold unless I was doing stagnant air.
NG777- just keep the air moving best you can. Not talking anything like a gale force, just something like a mild gentle breeze is good. But, it's really about keeping it clean (uncluttered) too. Just make sure that air flows freely around & thru your plants. You'll be fine.
While 40-50 percent may be considered perfect(?), 60-70 percent is not instant death.

Just checked mine. It's 72% (a low day), and I'm not concerned in the least. (ie; no mold)

Think about it. Cambodia, Jamaca, Hawaii, foggy old England, Oregon / Washington State. You think outdoor grows in them places is non-existant because of humidity issues? I think not.

Humidity also helps keep temps down to some degree. Let your plants go dry, remember the temps, water and check again in a hour or two and it's cooled (somewhat).

60%? I wouldn't be concerned (with some air flow).

Just had to but in and say the same thing realy, my lady room exaust kicks on at 60% but seems very hard to keep it under 50% at anytime, generaly running 55 -60 without any issues ever, lots of air movement and massive drying of the dirt as well, do notice as pots dry out humidity goes down, water humidity shoots.... I dont know maybe just me....

Thanks for the info guys. It just rained out so it shot up to 70%. I have a fan blowing on her and the humidity stays pretty much at around 59-65%.

Thought you'd find this interesting -

I have 2 of 2 types of humidity gages.
All claim 1% accuacy(!).

Group "A" reads 68% on one, other is 64%

Group "B" reads 74% on one, 71% on other.

Which is right?
That's 4 meters, with 10 points variation, on 1% rated accuacy meters / gages.

Group "B" was bought to go into Mason jars for cure (60-65% target).

I am not a happy camper! The ones for the jars deviate 4% of my targeted 5%. That doesn't leave much wiggle room.... and who knows if they're even close to begin with????? (bummed!)

Thought you folks would get a chuckle on my delema.

Guess I'll need to do this;

Relative humidity (RH) is measured as a percentage--absolute and specific humidity are NOT. If it reads in % it's a relative gauge. RH gauges are fairly inexpensive and commonly available. Gauges measuring absolute or specific humidity are hard to find and expensive; they also read in either g/kg or g/cubic meter (or the non-metric equivalent) not %. "Actual humidity" and "exact humidity" are not measurements.

Dial RH gauges are rarely calibrated properly by the time they reach your home. This is NOT the fault of the manufacturer. It is simply the way it is with this type of hygrometer whether it's for your tank or for your house. This probably accounts for the wide variation of humidity levels that have been recommended. You can do something about this though

Calibrating your hygrometer:
First check to see if your hygrometer can be adjusted. Look at the back to see if the small center post has a slot for a small screwdriver. If it does you'll need to have a screwdriver ready to make any adjustments as soon as you open the jar. If it doesn't, don't worry, this procedure will still allow you to use your hygrometer more effectively.

Half-fill a shot-glass or other small dish with table salt and add enough water to wet the salt completely but not dissolve it--it should be like wet sand. Put the shot-glass and hygrometer in a wide-mouth jar, and seal it airtight. After six hours (or more), the humidity in the jar is 75%. The hygrometer should read somewhere around 75%. If it does not, take the screwdriver and turn the screw on the back of the hygrometer until the meter reads 75%.

If your hygrometer is non-adjustable and reads other than 75% in the jar, you must correct all subsequent readings by this difference. Example: if the hygrometer reads 67% in the jar, it is reading 8% low. Thus, it will always read 8% less than the actual RH. Using this example if you wanted the humidity to be 60-70% then the reading on your hygrometer would have to be 52-62%.

Dial RH gauges can be off by 20% or more! They are also usually only accurate to +/- 5% and often take up to 2 hours to finish stabilizing to a new reading if the humidity changes. Please remember that it is simply the nature of the beast and NOT necessarily poor quality or manufacturing. The spring mechanism is delicate and goes through a lot (shipping, etc) before reaching your home.

I had a good laugh at this,, you defiantly put cali in his place.., anyways i was getting worried about humidity and mold on my just starting buds and after reading this my stoned mind is at ease. thanks again.
