Hey mate, first off I need to say what a beautiful grow you have going on! awesome stuff 
I was looking into going with a autopot system myself for my first grow and was wondering which particular one you went with? is your res on the outside of the tent? being a real noob at this I was under the impression autopot systems didn't require a air pump and get fed automatically via the res so if you don't mind me asking, is the air pump an add on to increase efficiency? if I could replicate this set up and get half as decent results as you have going on I'd be absolutely over the moon, anyway many blessings from Australia my friend and I wish you all the best with you end results
