That 600 is underpowered for 4 though. Hmmm....
I've been running each elite off one 54v 185A meanwell. So they get about 200w. Works mint and provides all sorts of flexibility around the 4 288 v2s running off the 600. I started in a 4x4, now onto a 4x8.
I would recommend spending a few extra dollars on more, smaller drivers for better flexibility down the line. The thing about growing herb is that it truely becomes a light obsession. When that obsession includes LEDs, there are infinite possibilities for expansion and upgrading. UV bars, sidelighting, etc.
For instance, I only had 1 plant in the 4x8 for a host of reasons (outdoors just came down and only wanted one indoor gal for my head). I shut down 3 of the elites, and had one direct over top (not a lot of training on her). Then the 288s got turned down a tad and arranged as sidelighting.
The result is massive chunky buds top to bottom. Granted, there wasnt a flattened canopy above to hog energy, but I may have to look into some bottom lighting w/ bars or something.
Notice the top of the lower bud that bleached out? It sagged into one of the 288s. Lucky it didnt cause massive problems.
