I use the soil and the nutes, both synthetic and organic, with their soil amendments. Flawless is an excellent way to describe aurora lineup. I also add calmag, green fuse bloom booster, bioboost stimulant, rootsxl in veg, and bud candy/floraliscious pro for the sulfur compounds. I am hoping to run their synthetic in hydro but I fear it may be too thick and chunky with all the molasses and yucca extract.
