Do I need a small fan?

Hi lads,


I am growing one autoflower and currently have a carbon filter inside tent with fan shooting air out, so I believe there is negative pressure in the tent. Do I still need to get a small fan? I am using led so it doesn't really get that hot too.

Thanks

Yes I would add air circulation, especially in flower

I completely agree you need circulation. I have a 5x5 and it may be overkill but I have 4 fans making sure I don’t have any hot spots. I strongly recommend at least three for any grow. Have it on your plants so they can develop strong stems.
