WTF My Humidity is in the 90s HELP!!!!!!!!!!

Hey I have tried to get the humidity in my flower area down but I can't figure it out. I know that I need to be in the 50s but it stays in the 80s and 90s with the lights off. The hum is around 60-70 with them on
Anyone with some help would be greatly appreciated.
Thanks

damn thats ridiculous, are there rain clouds in there???

get a dehumidifier quick

Whats the temp in there? You may need a dehumidifier.

No rains, the temps are in the 50s-60 with the lights out. And 70s with lights on.
I was thinking that is what I needed. I looked around the local stores and no one is selling them yet.
I have looked on line but they are like $200 and 50L units, I don't think I need one that big.

It needs to be warmer in there too. Sometimes a small heater is enough but ur humidity is sky high.

I bought a dehumidifier at a yard sale for $30 .I'm using it in a 12' X 18' X 8' room and it controls humidity well. It does run all the time though(24/7).in a smaller area it would cycle on and off as needed. There is a knob to adjust this,but I just keep mine cranked up all the way.

mine was 95% pretty much all the time lights on or off. its made my carbon filter stop working. temps are 30C day 20C night. bought a dehumidifier a couple of days ago, i ran it for a couple of hours and boom its a nice 60% it creeps back up within an hour of the thing being off though. mines a 20 litre i think, cost me £70 in the sale. there's loads on sale in the uk, i know that doesnt help you much. just letting you know they are worth the cost because unlike a lot of things these days they actually do the job they say they do

What is the source of all that water vapor?

ur lucky i cnat geta humidyt readin at all, i blwo on it and it says 60% but other than that it reads --%

you need to vent the air out keep fans on 24 hours a day or you will get mold on your buds

I have a 16" iso. fan on 24/7 and a 80cfm ex fan in a 6x2x5 area. I also have a 465cfm fan I use when the lights are on. This fan is blowing from out to inside the grow area.

The lights are on from 4pm to 4am.

If mould starts how will I now what to look for. Ive seen it on walls but what will it look like on the plants?

Oh you'll know.The first sign is often a musty smell, also grey powdery shit on the buds. About all you can do with mouldy weed is make bubble hash(I hear).

Thanks I will buy a dehum when I get paid. What size do you think I should get?

See what's available cheap. Check out yard sales,and want ads. You don't need a big one, mine is only small. I just looked at it and can't find a size,but it's only 44 watts, so isn't that big a deal for elect.

mine Burns 350watts and my grow boxes collectively are about 11 square feet and 4 feet tall, the bedroom they are in is about 100 square feet by 8ft high. i could of got away with a smaller dehumidifier but its nice to see the average room humidity drop by 25% within an hour

dude...i picked up these things that take a small moisture absorbant white granular thing....i think they made to take smells out of cubboards or sumthing.one will cost u around $5 and they work fuken well.my humidity was at 90%, with to of these units(it's jst a small dome thingy that u put the granules in and they absorb the moisure in the air as they dissolve and u left with a tub +-500ml of pure h2o.the granules cost $1 a packet and i replace them every month/empty the water.)i got my humidity down to 50%!

Silica gel??

i don't know what it's called man...it works fucken well tho.draws all the moisture out of the air around my plants!its not really a granule, but more a white, light, cardboard thickness, shale sort of stuff....if u catch my drift!i'll try find out wat it's called

Thanx,I'm just curious, but some people will want to know,it sounds good.
