First organic tent grow.....

the 7" stationary fan is just inside the tent with its back towards the intakee hole sucking air in

The flange is the metal rim portion of the filter that the ducting is attacked to. Why are you so worried about the humidity?

Tubs of wet perlite help raise humidity better than tubs of water alone. Might help.

Maybe get stronger fans or add a fan just play around with ur positioning of them everything else seems good
Good luck

im not worried about the humidity but i`ve got a plan to get it at around 50 and then gradually lower it throughout the flower stage believing this to get me nice thc build up and thanks goodro

i would like to get the larger ducting but my filter and exhaust fan are 100m the same as my ducting. the air coller and new ducting were slightly larger so i had to modify,hope everythings ok lol

I have never heard of humidity effecting THC production. Super high humidity can cause a flowering plant to have stringy or fluffy buds but it really doesn't impact the THC much. Think of there the best outdoor conditions for marijuana are; Humid regions of India, Pakistan, Afghanistan, and California. Humbolt rejoin around harvest time is damn near (if not) 100% humidity.

If you are worried about THC add some UV

Is that a cool mist humidifier? If not then maybe it is creating too much heat (vapor). I was looking at the setup and trying to figure it out. The air cleaner is sucking from inside the tent, running through the light fixture and out into the room? I don't have a tent setup yet and I'm only running a T5 for veg. but I plan on running a 600 in a 3'x3' type tent situation for flower "so I am very interested" (1.5m x 1.5m x 1.8m I think. Hope you get it dialed in soon

i have already been using a 125w cfl for nearl first 2 weeks of veg. yes it is a cool mist humidifier so thr`s nothing more i can do. gona try adding 2" of wet perlite and hope this helps. humidity`s fine when lamps off. i am gona buy some more 100mm ducting 2moro and run it from the exhaust fan away and hang it over the door which i must also keep open or it gets too hot again lol. this will vent the hot air completely out the room and hopefuully lower temp slightly allowing the exta bit humidity. i have heard that the plant makes more thc if the air getts dryer later on in flower therefore produces more thc to protect itself from burning. see my sense??

The burning is from intense UV. Humidity doesn't play a role in plants burning.

But by all means your plants will grow just a tad bit faster with the optimum humidity/health.

and tranka32 you`ve got it spot on,thats exactly how my setup is. my TT exhaust fan is at the end of the setup blowing towards the top of my open door.i have a 7" blowing cold air into the room from outside in passage ( cold air in nearest the floor and hot air escaping through top half of door,hopefully lol ). did try putting humidifier under intake opening of tent thinking this would slightly raise rh but instead the warm mist must be warming the air flowing in and it slightly raises temp

optimum humidity is very hard to achieve thus far lol

so you dont think the humidity will effect the quality,quantity or thc if i keep it as so??

I don't think it'll effect it one bit.


*******Edit
I should take that back. Everything makes a difference even if it's a small one. Your plants might veg just a tad bit faster but I don't think it will effect your buds. And keep in mind that once your tent is full of vegetative matter your humidities will be considerably higher than now.

ahhh thats a relief to hear m8 cheers. i hope ya ryt lol. im just gona stick with it and hopefully reap the rewards of my first nearly completely organic grow

still gona buy the extra ducting tommorow tho as its only going to get warmer as days pass into summer and my temps are still round the higher levels.bit worried bout later on in grow and keeping temps down then

i just seen your editing m8 its always about the buds hope they are dense juicy fat crystally mothers lol

gona keep a diary on here so you`s can see how they`re going just been and bought 10 meters of 100mm ducting to stick on end of exhaust fan so i can direct the heat from the room into the passage were i have a cold fan blowing onto the hot air being expelled. think this will lower my temps and humidity will go up

That should definitely help quite a bit. Glad to hear you'll be journaling your grow.

well it did help. i`ve put it how i said and the cold fan on to the hot air is working a charm.no condensation on the windows at all i`ve even knocked both the oscilating and the 7" fan both down too their first settings so thr`s still abit leeway for them to go up a level each when the summer temps come.

todays pics few seemed to be slightly drooping like the back right 1?? they werent watered yeaterday tho,only day before and just before i took these pics today
