I managed to get myself a grow tent DR120, the fan is a RVK125A1 I think the fan is a bit too powerful for the size of the tent so i am blowin air into the tent from the bottom and im getting plenty of extraction blowing out of the top. The temp is aroun 74 and the humidity is 38 would it be better to extract instead of blowing in? And also is the temp and humidity fine at that rate?
Many Thanks
