Well even in the 5x5 lol, 7 Photo-Peroids are getting huge and out of control, so I setup my 2x2.5x5 Gorilla tent in my closet and put the Aurora Indica in it and its under the Kind K3, for exaust I am using a 4inch Ventech 190cfm it think... I can really speak on VenTech I have had this 4 inch for probably close to 3 years now and it still runs fantastic... I do not have a carbon filter because smell is really not a big deal for me... I do have one in my big tent but in the small one it just is not necessary... Today is feed day and I will throw down some pics.. All of the gals have been switched to flower they have been for about ehh 2 weeks, the Aurora and Skunk [HASHTAG]#1[/HASHTAG] are the only 2 that do not have popcorn nugs yet.. I am sure we will get there. I have really not done a really good photo shoot with this group, I am in alot of pain but I am going to get some good pictures today, Much love guys I will see you when I post up later on!
