Pretty much any brand of nutrients will work. Just read the instructions on the label. It would be cool if you can find an organic solution that works. If you run a 2-part then I'd choose to run a sterile res. That means killing off any and all bacteria with H2O2 or bleach. If you run a live res with bennies then make sure you keep the water cold. I've been recommending a water chiller to avoid root rot. Unless you keep your room cool it's pretty much the only way to go. My next design will be using coco fiber/perlite mix with 100% organic nutes.
