Air circulation

[Troy Horn]

Hi All,

I’m a first time grower and recently purchased a grow tent kit.  So I have the inline fan set up and also bought an oscillating fan. I was just reading an article about air circulation and it repeated several times to make sure I connect an “air intake” fan at the bottom of my tent. This was the first I’ve heard of this, so my question is, “do I need to add this fan to my set up if I already have the carbon filter, 4” inline fan, and an oscillating fan? Again, I’m a rookie so if anyone can provide some clarification it would be greatly appreciated.

Thanks in advance,

Troy

Hi Troy,

Congratulations on starting your grow journey! Regarding your question about adding an additional intake fan to your setup, you’re actually good to go with what you have. The combination of your carbon filter, 4″ inline fan, and oscillating fan should provide adequate air circulation within your grow tent.

So, no need to worry about adding an extra intake fan. Your current setup should suffice to maintain proper air circulation and ventilation in your grow tent.

I have the 2×4 grow tent kit and had the same exact dilemma.

currently closed all intakes and just have the 4” in line fan and ducting out of one of the air vents all other intakes have been tightly bound using the attached toggles.

currently have tent walls which are bellowing out which I beleive to mean I have positive pressure. But a total noob so working on assumptions. Any advice or clarification gratefully received.

thanks

Hey

As long as the environment (vpd) is in a good range you are ok. Second fan can be used to be able to control the vpd but it is not needed in most cases. Happy growing ?

Welcome to growing! You don’t need an intake fan if your inline fan is creating enough negative pressure (walls sucking in slightly = good airflow). That said, I learned airflow the hard way—my first grow got as steamy as a granules for hot tub spillover because I skipped passive intake vents! Now I use the oscillating fan low near seedlings and keep my tent flaps slightly open at the bottom (like how you’d balance granules for hot tub pH—small adjustments matter). Watch those leaves; they’ll tell you if airflow’s off!
