I bought a similar product from my local home improvement store and it was not getting the job done 400 watt HPS in a 8' x 8' x 8'. It was useless.
This is more like what you need. You will be glad you did. You will need a larger fan (more cfm) if you are going to connect it to a carbon filter for odor control.or getting just one of this

or two..?
this is just to cool the rooms, again 400w mh in 4x6 and 600w hps in 8x6

I had the same problem and solved it with a humidifier. Some folks hang wet towels in the room or buckets of water to evaporate. I think you will need a humidifier for veg as you are in the low 20s.update, that 4in htg fan is working just fine, keeping temps steady at low 80s high 70s. definitely a bit loud tho.
my humidy is low in the 20s.. how do i fix that?
