Placement of carbon filter

That is just weird, you should slap it in the other way around, put the carbon filter inside the tent, fan on top of tent, as little curves as possible in the exhaust and you won't lose any power. it should be pulling the air into the carbon filter then going thru the fan, not having the fan forcing the air out thru the filter, they were designed to work the other way around. there is an outter layer you could buy called the pre-filter, that helps ya out too. stay lit growmie.
