Well so far it looks like a got a handle on this heat issue. Removed all 3" untill where it goes through the window so basically removed about 8' of duct and eliminated about 3 bends :thumbsup:

On a side note, the two plants we had in the cabinet and cut down this last weekend ended up being a lil over 4oz dry. Not shabby for 2 plants I guess. Cab is now retired and new home for new Momma.
