Larry Badgeley Posted July 14 Share Posted July 14 Morning all. This may seem a dumb question. I've cropped my 4 ladies and they are hanging in the tent. Extraction on low and a USB fan blowing against the wall. Do I still need a passive air flow of air coming into the tent or do I seal all the holes up so no air gets in? I just can't remember what I did before. Thanks Link to comment Share on other sites More sharing options...
bushdoc Posted July 14 Share Posted July 14 Just passive intake is fine and prob don't need the USB fan on 4 Link to comment Share on other sites More sharing options...
Military Grade Posted July 14 Share Posted July 14 Keep the passive intakes open mate, better air flow will be more beneficial, and it's not like you have to worry about light leaks now Link to comment Share on other sites More sharing options...
Slippy One Posted July 14 Share Posted July 14 Def don’t need the usb fans running. 2 Link to comment Share on other sites More sharing options...
Military Grade Posted July 15 Share Posted July 15 @Slippy One I stopped having a fan on years ago, without any issues either mate 1 Link to comment Share on other sites More sharing options...
Larry Badgeley Posted July 16 Author Share Posted July 16 @Slippy One @Military Grade I don't mean on the plants. Just on low at the bottom of the tent facing the wall. I thought good air movement was beneficial? 1 Link to comment Share on other sites More sharing options...
Military Grade Posted July 16 Share Posted July 16 I think it's air exchange that's beneficial, that's taken care of by the extractor fan 2 Link to comment Share on other sites More sharing options...
