Extraction can size for 2x2x5 tent ?
Hi guys I'm about to set up my first box, I'm missing just the extraction. Box is 2x2x5 and I've got led light 120w. No smell is the most important for me. Is 4" fan with carbon filter going to absorb all the smell? Many thanks !

Should my inline fan run perpetually?
I read it's important to exchange the air in your grow area once per five minutes. Because I read that, I've had my inline exhaust fan running in my tent since the beginning of my grow. Is that right?

High humidity during flowering
I don't have an exhaust fan since this is my first growth and I'm quite on a budget my humidity averages around 65-75% I know high humidity increases risk of mould and bud rot is it necessary to get an exhaust fan and aiming for 40-50% or just risking the consequences?

Growtent Humidity control
How do you control humidity/temp when using a grow tent? is it enough to put a dehumidifier in the same room as the tent and close the tent and just blow the air outside with a fan and tubing? Do u need an intake fan too? Or does the "good air" gets sucked in enough without ? THX

Fan vs Fanless LEDs
How effective are heatsink LEDs? I'm not sure if I should go with fanless (like Mars Hydro SP150) or with a fan (Mars Pro II Epistar 120). I struggle with heat, when the tent is closed it gets to 29-30 degrees with humidifier in full swing (HID lights) and I want to close it soon

Connecting intake fan to my tent's mesh for most efficient ventilation
So as a couple people suggested, I bought an intake fan, and am using it to bring air in from a different section of my closet. How can I stick the ducting to my tent's mesh? Is tape fine? Any other ventilation tips?😉😀

Ventilation Setup for Smell Attenuation
Is this setup ok? Since the air tent will be recirculating i think the smell will be atenuated. I haven't seen other growers with this setup (I'm a newbie though), so I wonder if there's something wrong with it.

Co2 bottle question (Tnb)
Should I be running my exhaust fan and intake fan during the day while I have a Co2 bottle in the tent, or will Scrubbing air make adding it useless?

Smelly room, with filter should I be able to smell flowering buds?
I have a 3x3 grow tent with a 4” fan and filter. The filter is in the tent and exhausts into the room. I taped the filter to the line and line to the fan so no pinhole leaks. The fan is rated for 198 cfm. I have it on low because when it’s high the smell is worse.

What u guys think im good with all smells with Vents TT125 220-280m3/h and Phresh filter 500m3/h? I think 500m3/h is little bit oversized but cant find smaller Phresh filter with 125mm flange but what i read oversized filter isnt bad thing?

What’s up guys me again😂 I’ve got my hps up and running and I’ve got the temperature under control by having my fan blowing directly at the light and I’ve added a oscillating tower fan. How can I keep the temps up when lights go off? Many thanks!
