Great work! I think you'll be pleased with your choice to make a jumbo pan rack and a morter tub rack. You can put 1.3 - 1.4 in each morter tub and use the other rack for preggo's. If you ever need to up production you can bump that up to 1.5-1.6 and build another jumbo pan rack and a growout rack out of the large morter tubs. Again, looks good!
