Humidity...?

IM HAVIN ALOT OF PROBS GETTING MY ROOM JUST RIGHT, FIRST ITS THE HEAT, NOW ITS THE HUMIDITY...?
IM RUNNIN FRESH AIR IN AND THRO MY LIGHTS AND OUT OF THE ROOM, CO2 LEVEL IS HOLDING STEADY AT 1200-1350
TEMP AROUND 79NIGHT - 83DAY
BUT MY HUMIDITY IS UP IN THE HIGH 60-70
PLANTS LOOK GREAT, IT STARTED WHEN THE WEATHER CHANGED AND I NOTICED ALOT OF CONDINSATION ON THE DUCT RUNNING IN FROM OUTSIDE, AND UP TO THE FIRST LIGHT, COULD THIS BE THE PROB, AND BY SWITCHIN BACK TO INSULATED DUCT SOLVE THE PROB.

THIS IS MY SECOND RUN, TRYIN IT ON MY OWN, AND THE FIRST ONE WAS A 50-50 FAIL WITH SOME G-13, NOW IM RUNNIN BUBBA KUSH, AND ITS A EASYER STRAIN FROM WHAT IM TOLD,

nothing at all,50%-70% for veg,%50%-35%flower, imo

Ok, i read somthin about 80% and mold set in the walls....
But it hasent got that high yet

Carbon scrubbers also become pretty useless when the humidity gets above 80%.

Yes, your humidity is too high for flowering.

With any reasonable buds you'll get mold in no time (although your high-ish night temps could help you out in that regard, but why chance it).

Anywho, just buy a dehumidifier - like $150, problem solved.

Really, that simple....
What about the condesation on the inlet duct...?
By morning, its dripping everywhere, im using the 8" thermoflow duct (it has no insulation)

Well, I'm sure I'm not telling you anything that you don't already know, but that condensation is from the humidity in the air.

Remove the humidity, and you remove the condensation.

FYI, get the biggest dehumidifier that you can fit in your room - it'll run less and you'll have to empty the tray less.

I had to buy a small one to fit into my tent (25 pint), and I have to empty it every few days (more when it rains).

And if you're hooking it up to a Sentinel or other atmospheric controller, make sure it's one of the older models with a knob instead of electronic controls - the electronic ones need to be re-started manually every time they turn off, which doesn't work for me and my Sentinel.

If you just need a nice big one for your whole room and size isn't an issue, just go on Craigslist - you can get a used one for nice and cheap which will take care of your problem.

Good luck.

Thanks guys,
i run a greenair enviroment controler, and it deos have a set knob for humidity
ill try that, thanks

Then make sure to get an "old school" dehumidifier with knobs - trust me.

The other issue that people do not consider is that a dehumidifier creates a buch of heat due to the compressor inside so you have to watch that as well.
