You’ll pay more for quality LED fixtures But you’ll have significantly better lighting. I know there are a lot of QB fans, but that type if light source is very center weighted so anything not directly under the light is getting much lower PAR. Bar style fixtures from Fluence, Gavita, Mammoth, Chilled, etc produce more even PAR maps over the canopy.
You might also want to consider a 5x9 tent if you have the room.
