DIY COB frame layout qestion

I purchased 300 watt Citizen CLU048 (6) COB grow light kit from Timber lights for my 2x4x6 grown tent and I’m wondering if I should lay the COBs in one row six evenly spaced or would it be better to two rows of three. what do you think is the best and why? In my tent I have 4 white widows growing in 3 gallon fabric pots SCROG’d. Thanks for any input!

2 rows of 3

shape of your tent is the only factor really
