The center box on west wall veranda level is new this year.  It’s about 9 cu. ft. of root space.  This spot used to hold 2 3 cu. ft. containers.  Making one big container increased root space by 50%.  The vines are doing extremely well this year in general and this box in particular.  Much of this might have to do with the continuous wet and cool weather we have had this season so far.
