D.10 placed into grow system. Source water is high 490ppm with high calcium Mag content, no additional cal Mag needed. Adjusted dimmer on lights to 300 total watts currently.
@TickleToast, they've treated me well so far. 4th run and still seem good to go. When these go out, I'm going migro array. Same diodes but spaced out farther allowing closer hanging heights and good even spread. With my current hlgs I'm getting mostly 870 to 1050 umols with a few 700 spots, but I am not using my full grow space.
