Vacuum

[AndyOakie]

i have a 6 in outline fan sucking aroma n hot air from hoods to outside, and have a 4 in inline bringing in fresh (Co2)... i think there may be to much negative vacuum effect going on.. or is there even a such thing as to much neg. vacuum? any idea on how to regulate vacuum effect, maybe switch out the 6 in for the 4in and have the 4 in do the outline and 6 in inline?

Hi again AndyOakie,

A little negative pressure inside your tent is a good thing generally speaking. Are you seeing any negative effects from it?

my humidity is staying lower than normal but with an 8x8x4 tent cant expect perfection in there
only have my vegetables in there now besides the jane in germination but the veggies are looking great.

Look in to a fan speed controller so you can slow down the 6 inch fan..

I have to agree with Jedthedog on fan speed controller. I also have to run a couple smaller humidifiers, at various times of the year, to keep humidity up.
