In hydroponics, the fertiliser provides all of the plant's nutrition. Formulas differ by the number of bottles: one bottle for simplicity, two or three parts to fine-tune nutrition at each stage, from growth to bloom. Choose the soft water or hard water version according to the hardness of your water, and a dedicated formula if you grow on coco coir.
The mineral nutrients in this collection are not suitable for an aquaponic system with fish: for aquaponics, see the aquaponics supplements. Then adjust the solution with a pH adjuster and monitor it with an EC meter.
