That's a cool setup. One problem though ... They recommend using a 2" hole saw to drill the holes in the lid. Then they also recommend using 2" net pots. The correct way is to use a 1 7/8 inch hole saw to drill the holes in the lid. That way, the net pots wont fall through the lid. *lol* Trust me ... I made that mistake on my first attempt at building my DWC cloner.
