- Thread starter bguwop420
- Start date
I'm reading that the T4 is better so I got that and some ducting ..now I'll have everything but a dehumidifier and I guess a Humidifier too..how important is that compared to a dehumidifier?

Depends on where in the world you reside.

That sort of depends on your environment in general. The fan can be programmed to ramp up or down in speed to control heat and humidity in your tent if you can vent entirely away from the space you are in. Otherwise you just recirculate the same hot humid air. I vent my tent out a window, so replacement air gets drawn into the tent.
Midwest it's very humid
Midwest it's humid alot and ok cool what about a carbon filter can I do without if I'm not worried about smell right now
I'll probably get one later in future but when this exhaust fan comes I'll have everything I need
I have my medical card provisional and will have the official by next month just waiting on them to email it

There are still laws about nuisance odors. A 4 inch carbon filter is not going to break your bank

Not to mention, 1 plant will most likely make your entire house smell, especially if you don't vent to outside.
Ok I'll get one then I think it's only like an extra 70$

I'm sry I know im gonna piss someone off but if you can't do the math and figure out what fan moves enough air for your tent then it's gonna be a long grow for ya... this is way to common a question, and it shows people just want the answer, not to understand how to come up with the answer. You didn't even tell us what the cfm is of each.
That being said assume once you put a filter on it you'll loose 33% to 50% of the air movement but your tent is small. Either will be just fine

What's Cfm? I got a 4in AC infinity exhaust fan, an AC infinity 6 in oscillating fan, and a 6in Hurricane fan..how will I lost 50% of air movement ? Is it because I won't have a carbon filter..if so I'll buy one it's only 50$

Cubic feet per minute of air moved. Fans tell you the cfm unfiltered most of the time... filters tell you how many cfm they are designed to work with. When u put a filter on the fan it allows less air thru so you loose some cfm.
You want to change all the air in your tent say every 2 or 3 minutes. So you need the volume of your tent in ft and compare that to your fans cfm. I always go about 33% bigger on cfm cuz I know I'll loose that when I apply the filter

You must run it. You are suffocating them if it's off, and making humidity spike like crazy. They will use all the carbon dioxide around a leaf in seconds.
Lighting and air exchange are 1 and 2. You should go watch ultimate grow 1 or something like that
