The Flora Trio is three bottles (FloraGrow, FloraMicro and FloraBloom) which are combined in differing ratios depending on your plant's stage of maturity.
General Hydroponics – like most if not all nutrient companies – try to sell their base nutrients with a bunch of other supplements, but using just the three bottles mentioned will do everything you need in addition to saving money and you will be surprised how keeping it simple can still produce excellent results and big yields. This comes with a feeding chart to help with mixing and they are Quart sized bottles. - Gary
