no need for input fan, passive intake and negative pressure will do the job with an extractor 150 to 200 m3/h running 24/24.

my appartement is 30m² i sleep next to the tent and i have a 225m3/h fan running 24/24 for a 90x60x180 tent, sound isn't that much

Your light can be the most costly item you’ll buy, so I’d recommend checking out some lighting videos from Migro on YouTube. I learned a lot about the science and what to look for, especially PAR maps and spectra for various lamps. High quality Samsung LED diodes (LM301b or h) are a good investment. Trusted recommendations here can help tip the scales.

I also agree with @Goodshit97 to buy what you’re pretty sure you might want if/when you upgrade, not just what you think you’ll need now.

You’ll want an LED lamp that completely bathes the floor and corners at the proper light density.

Also, matching the exhaust fan to the cubic space is important, as is matching the light to the tent’s footprint. Someone here suggested buying a higher output fan and turning it down—I agree. ACInfinity makes very high quality fans and filters, and an excellent environmental control phone app that makes growing more automated—great if you’re growing in a shed and don’t want to run back and forth to check your grow.

Are you planning to grow autoflowers?

I have a 2x2 with a ViparSpectra XS1000 that is working well. The XS1500 would also be well suited for that size tent. More powerful lights than those would be too much power for a 2x2, in my opinion. That depends on the height of the tent. I am using a shorter tent because it's just for seedlings and early vegetation. If the intent is to grow all the way through flowering, then I would recommend a tent that is higher than the one I'm using.

Ididnt plan on autoflowers no,, is  that good?

About the fans,, do i just need outline fan with coal filter? When the tent is tight to make all small inside how can it get fresh air in then? I thought i needed fan inside with a fan going out at higher speed to make anegative pressure?

extractor will suck the air into the tent from the passive intake creating negative pressure into the tent, i work with prima klima for coal filter great brand.

and a 15w to 20w oscillating fan between the led and plant top is recommended

No, I have a 100x100x200 cm tent with a 6-inch ACInfinity exhaust fan, it sucks plenty with no help.

In a shorter tent with a light fixture and exhaust filter, you’ll be losing a lot of “headroom” that the plants can’t use. Autoflowers are often shorter and may work in your tent, but I’ve not grown them myself.

yeah but that's really not needed. both mothamn and me and many others don't use intake fan, and just passive intake +extractor+coalfilter

Ok,, but passive intake, what is ment by that? The air that is locked in the tent? With new air if i open tent to waterplant?

passive intake + extractor create negative pressure inside the tent.

As long as you have flow through air and not too many plants a small 4" with a dimmer switch attached works great. In the winter ( now ) I have one turned down as low as it will go with 8 plants in 3 gallon pots...if the humidity climbs too high I turn up the fan as needed...In the Summer it runs full blast 24/7 sucking humidity & heat out....

I have a house bathroom fan I boxed up and put an input and and exhaust ducting on it. Its been running 24/7 for 4-5 years now, in my veg closet...silent and efficient
