humidity again killing me

hi guys quick question about humidity again i have sort of combated it but u guys would not agree, The only way i can keep it in check is when lights are on threw day i have to turn 3 fans all oscillating off and the humidity drops to 40-55% but as soon as i turn any of the fan on it goes back into high 60s and also on a night with lights off i keep fans on all time to combat wet spots, I have a crappy intake with about 185cfm attached to an outside vent this is venting air in and i have an 6 inch carbon filter attached to an tt fan that moves 485cfm out of my room. Carbon filter must be working as i cant smell anything at all even in the actual room i can just smell it so i need to know where to improve as at min im having to turn fans off all the time to sort it and at 1st i thought the dehuimidifier i had was'nt working so i bought a 12 litre 1 yeah it pulls the water out but from where as i have always high 60s for humidity i want 40s all the time no higher what can i buy to achieve this also before u all say a dehuimidifier i would just like to say i have spent about 400 now on 3 different 1s i feel like a car boot sales man hahahaha thanks for any help u can offer me

also to clarify i have 4 in a nft pumps constant running and across the other side of my room i have 2 in plant pots im thinking 1 thing to combat this for next time would be to get rid of the nft and maybe go to pots, I have a wilma if it be any easier i only just bought not used yet tho as 21 days into flowering on all, as an afterthought can any 1 tell me how to find out about the plant im growing on what its best conditions are like mold resistant and stuff as i have been reading lots of things and it pretty much scares me

amnesia haze got as clone of friend
blue cheese same as above
the widow clone

thanks again buds sorry if writing isnt the best

i really want to run all my fans all day not just the intake and extractor

Maybe you can supplement it with some of these http://www.bedbathandbeyond.com/store/product/damprid-hi-capacity-moisture-absorber/1017732404?device=c&network=g&matchtype=&mcid=PS_googlepla_nonbrand_cleaning_&gclid=CN6pw4Wx5bsCFaTm7Aod4R0AAw

any news on how you managed to handle the humiditiy issues Droidboy?

Sounds like you just are not buying the proper equipment. You say not to recommend a dehumidifier, but that is what you need, just the right one. I have a 60ppd dehumidifier in a 11x10 area that is for veg and flower, they share environments, with 70-90 plants and humidity stays exactly where I want it. I don't have exhausts or intakes, completely sealed room.

For a quick and dirty diy dehumidifier. grab a small window ac and install a drain in the bottom. throw the whole thing in your room and go!

To me getting moisture out of the air is so easy with a good dehumidifier. Of course it cost like 500 bucks but it works good. I keep it at 40

yeah i got a half good 1 at 12 litre extraction a day but it has been more of a PITA than anything else its just stealing my res so i end up topping it up every few hours, unless 4 plants are drinking 15 -20 litres per day. Its a real weird issue as 1 side of room is 40-50 rh and the other side about 3 feet away is at 62 all the time i have decided to try my best to battle it out for another 30 days then im going to replan my room as it was a pretty ghetto setup but now wife said its ok for me to do it so i can have the bigger room

I advise you to leave the fans on when lights go out. The dark period is when mold starts, its better to be in the 60's with fans than 55 with no fans at all.

Its because you don't have the right equipment. 12 lpd? That's tiny.. Get the proper sized equipment or stop complaining

well if the de=humid is drinking your res move your res away from the de-humid have the right temps moistures and air flow is more impotrant than you loosing some water from your res

What kind of dehumi do you have? Does it heat up your environment when its running?

I have one from Walmart. Had it for years now and works great. Any dehumidifier will have heat output, that's how it works. But I accounted for that along with the co2 burner and lights when I chose my ac.

I have this 1 http://www.diy.com/nav/fix/cooling-air-treatment/dehumidifiers/Blyss-16L-Dehumidifier-11787520?skuId=12298226 only mine is the 12 litre version and its crap, had this in cellar and old dehumidifier upstairs as its only a 3 or 4 litre so switched em around and with the new 1 upstairs it doesnt even keep condensation of window where as my old 1 does so im not sure but no matter what i cant get that humidity down buds the new 1 also has settings 60% 40% and constant no matter what setting i use it doesnt seem to keep it down the main reason i bought is because theres an adaptor on back to fasten tube and attach a container to use as overflow saves emptying it all the time. This is only my 1st grow and for my next i intend re-planning some things
