I would like to build a vero 29 gen 7 grow light to cover 2ft x 3ft (6 sq ft) it will be for a few auto's and a few photo,s for vegging. Where is what I was thinking about getting, #5 - BXRC-30E10K0-D-73 (37.7V), #5 - 140mm pin fin heatsink and #1 - HLG-240H-C2100B is this a good combo for 6 sq ft?
