I have a mars tsl2000 over a 2x4 and it kills that space.
I’m in the market for a different light and I’m going to to go high end with HLGs or I’m going to build my own with Bridgelux. I haven’t decided yet.
My mars has been going 12 hours a day, everyday, for over a year. It consistently pumps out awesome harvests. I even hit 1.5gpw but genetics helped a lot.
I also have an old mars blurple from 7 years ago that’s still kicking. And one of their tents too. Go mars hydro! They don’t pay me to say this.
