Help redesigning DIY setup

Hey. So I've had my DIY eb2 strip setup consistenting of 20x 44" eb2 strips and a hlg h600-42b @.7amps in a 4x4. All in 3500k

My considering is to tear it down and build a 3x4 por even another 4x4 and then a 2x4 pr 3x4 with just new drivers. I really love the minimum current serup but I'll probably double it to 1.4amps and just just a 50k pot for future adjustability.

I'm only three grows in but I'm also wanting more lighting control. Specifically in a pwm management type of setup. Wifi would be great but mostly I just want to be able to turn the knob and know how much power im sending to the unit. Gradual on and off stages would be cool too.

Anyways I was wondering what you guys thought about this concept and if you had any inputs links to any cool stuff for this build or whatever else you feel you should share.

Oh I also have c channel alum so they wont be droopy on my next build.... that drives me nuts lol
