HLG vs HSP for my first lb grow?

[Cannygrow]

Hello fellas I am branching out my 2x4 grow tent into a grow room I am building that is 6ft wide 2.5 feed deep and 6feet tall.I currently own an hlg v2 288 and know for fact it is not enough light to cover that footprint so am wondering what are some opinions regarding either adding a 400w hps for some heavy dense nugs or just stick with hlg and get one of them 135 watt boards. I am going to be running autos
Colorado cookie auto by dutchpassions
Girl Scout cookies by fast buds
Big bomb auto by bomb seeds
My goal is to pull a lb within that space using ffof

2 hlg v2 288s should work. One for each 3x2.5 section. Adding a 400w hps would be fine too, I just like to keep mine all the same but that's just me.

I was thinking the same but the budget is looking tight until I complete this grow so right now I either the 400w hps or the hlg 135 board. Am doing nothing but autos and am going obiialy going for the biggest yield. If I can average a 1gpw on the 135 board and 288 it should be easy enough with they’re efficiency but I’ve never ran hps so my skills and experience in that is limited. I will be running it in fox farm ocean forest as well
