I bought my coco and perlite on Amazon, the coco I use is the general hydroponics cocotek. I use and like the HLG 600 R-spec light along with a few extra small no name strips for side lighting (I have 6 10w strips). I use Blue Lab pens for Ph and EC. I’m not necessarily saying what I am using is best, but it’s what I’m using now and works for me.
