Moby Dick, soil and New LED G4X50W (led quad grow)

[Hogsihi]

Hello,
Ty for a beautiful journal

I am about to order some COB led light, chineese made.
My model is using bridgelux chips, did your also used same brand?

My area is 1/1.2meter so i will be getting around 400 to 500w.

Also how is the coverage of these lights? Better then the 3w spread sheet models?

Again thx

Thx
