LED supp help

Okay so I need all of you LED nerds to help me with my supplemental lighting for my 3x3

I'm running x2 HLG 135w QBs in a 3x3 tent

I'm wanting to push my wattage per sq ft ul a little as well as add a little but of bulk in flower, what's the best choices for that? I'm wanting to keep it as easy DIY or plug and play as I can

A couple of 50w SolStix placed as outriggers to the QBs or as sidelighting would do wonders, especially the red/blue stix.

Pop the dome diffuser covers off some cheap LED 2700K screw ins....
Easiest DIY imaginable.
