air circulation

So I've converted a cabinet that I was going to get rid of into a little grow chamber because where I was doing it before had 'height' and space issues. I'm 95% done but when I connected the extractor fan, it was way too noisy for my liking (this is in my room), the question I need to know is...

What up y’all my a/c just took a dump and now I need another one so I’ve been looking around and there’s so many options available. But before I get one I wanted to see what the rollitup community has to say about it any recommendations?? Need a reliable 14,000 btu air conditioner!

I got both dehumidifier and in-line fan. But when I get high humidity in grow space and didn’t want to wait for the dehumidifier to takes its sweet time I would turn on my in-line fan and put it on max or close to max and humidity levels would drop, it Gots me wondering is a dehumidifier even...

my green house had 5 fans but its pushing hot air around . what do i do?

Has anyone ever used just their exhaust fan only in a tent and used the negative pressure to bring air through the canopy and not have to use any extra fans inside doing the work and have no problems?

Hey guys! Thanks for reading. title says it all. Had a lazy day and I ended up watering around 4pm today. Light schedule is 6am - midnight for reference. I try to water around 9am usually but.. Soil is 75/25 FFOF and Mother Earth Coco-Peat. Mixed in some mycos when mixing and at transplant to...

Total newbie here. I have set up a 48”x24”x60” tent with a king plus led 1500watt light and a terrabloom 160 cfm in-line fan. My ambient temperature in the room is 22.5 - 23 degrees Celsius. The temp in the tent with the light on is staying at 26.5-27 degrees. I have the tent flaps open on...

Hello friends pls help someone with expirience :) I'm doing cloeset grow : Light is SF2000 with 100mm Prima Klima extraction fan (280 m3/h) with speed controler and carbon filter, so my question is: *Can i put 120mm PC fan something like "Noctua" for my air intake will that be enough for...

I’m using an AC infinity 6” fan in a 4 x 4 tent which is a fairly high end fan with probe and controller etc and definitely an overclock for a 4 x 4 as I originally got it as a top end fan for a 5 x 5, I get the importance of an exhaust fan to control odor mainly but secondary as a means to...

I recently created a file cabinet stealth grow box with interior dimensions 15”x26.5”x40”. I have the entire setup ready to go, however I’m extremely paranoid about air circulation through the canopy to disperse heat and strengthen stems. I had a smart devil 3 speed usb fan...

So I was talking to a friend of mine about ventilating two small tents w one 200cfm exhaust fan. The conversation got around to controlling the room the tents were in instead of just the tents.. we discussed several different options and I was wondering if anyone on RIU could throw 2 cents in...

Hey everyone, Im in the middle of my first indoor grow. I’ve been using the passive intake vents all of veg. I’m now switching to flower and I will need to put the flaps back on since the room is sometimes used and I don’t want any light leak. Should I set up another line of ducting for my...

So I have a few things for my first tent and I'm after ANY advice or feedback/tips etc. Lighting: I am happy with my light and will likely stay within the viparspectra range. Although 450w seems a little too conservative for someone like me. I also want to allow for future expansion. Is...

Hello, This is my first time growing and I bought a grow tent that I have indoors in an outside shed. I tried growing a couple plants and they seemed to be struggling due to not having enough fresh air. I have a box A/C unit in the shed since I live in a typically hot climate (though we do...

Can I add a mix of water baking soda and a lil dish soap to rid my plant of white powder mildew during Flower cycle? And how will it affect my Hindu Kush plant that's early into flower if I remove the heavily affected leaves? . I have ventilation problems at the moment and I'm trying to remedy...

I'm on my first grow in a home made grow tent made of PVC and wrapped with this 94% reflective stuff I found at home depot. The door is a light proof curtain that I put some of the reflective stuff on the inside of. I had just one 7" fan blowing the air above the plant, but recently it has...
