I'm 7 weeks into flowering in a 4x8 tent and while my plants were taller, my canopy was about the same density at flip, I might have had a little bit more tops but it got crazy crowded, I had to do I believe 3 heavy defoliations taking most every fan leaf that was fully developed each time I defoe'd. I didnt do a great job of lolypopping though which didnt help at all, but with all that being said I ended up having one plant die on me because of a plugged drip line and also had to take my biggest plant out too and now at 7 weeks it's as full as I'm comfortable to have it. I've got a shit ton of air movement in there but still crossing my fingers for no bud rot or anything as dense as it is in there. Also has caused the plants to not be filling out very deep into the canopy but I also am only running about 950w because of heat issues.
Thats just my experience with a heavily scrogged out 4x8. Itll help alot though not being confined by tent walls. I'd say lolypop real good with some defoliation and go for it. Keep us posted
