Thanks guys for the info and the links...Really do appreciate it...I will carry on with the suggestions and I will purchase extra clip fans coz I have to say my grow tent is slightly bigger about 1mx1mx2m...Discus I know high humidity is really important but I think my fault was I underestimated the size of my tent...my intake fan is only 4 inches which is really small and I really need to get the air circulating....Thanks for the input guys...))
