Drip System Setup Sketch

I drew a little "Microsoft Paint" sketch of the recirculating drip system I'm planning to use for my upcoming grow. Would this be successful? the drainage tubes would be attached to holes in the bottom of each hydroton filled pot via a grommet ( http://www.hydrohobby.co.uk/images/product/grommets.jpg ).

i think its close. the drain could get clogged being on the bottom of the pots. also think about putting a drip tray between the pots and the table
