No. 1 Basic nutrient Hydro is a highly concentrated basic nutrition that should only be used on hydro for best results. To ensure crop safety, the use of a temperature-compensated EC meter is required. First fill the nutrient tank with water and then bring it up to the desired EC. We recommend starting with an EC of 1.4 and ending with an EC of 1.8.
The PH Perfect System makes the use of PH-minus unnecessary for the soil variant, as the correct PH will always be obtained after adding the Basic nutrient, regardless of the type of irrigation water. For the hydro variant, however, we recommend using PH-minus according to the Hydro nutrition scheme.
