Uniquely amongst leading brands, T.A. Dual Part Coco doesn’t need additives for success from seed to bloom: other coco specific 2-part nutrients require additional Cal/Mag and PK boosters, as well as 2 bottles of “grow” and 2 bottles of “bloom” nutrients. Not so with Dual Part Coco®: two bottles are all you need! Dual Part Coco® is exceptionally rich in calcium and magnesium, but it also contains the full range of other elements that a plant needs for healthy vigorous growth, followed by bountiful flowering and fruiting. This includes the trace microelements which give your final product all the aroma and flavour that your plant is capable of developing. As with most of our nutrients you use both Dual Part Coco Grow and Bloom throughout the lifecycle of your plants; you simply change the ratio between the two as your plants progress: there is no second set of bottles to buy when you go from grow to bloom.
