The Ultimate Plant Fertilizer for Hard Water

Water quality is a crucial factor when growing plants. For optimal results, it's recommended to use water with minimal salts. However, this isn't an option for everyone, and some growers have to use water with high mineral content. In most cases, water quality issues arise from higher calcium levels, which can lead to nutrient lockout when using regular Holland Secret Micro.

Introducing Holland Secret Hard Water Micro, the ultimate solution for those dealing with hard water over 200 ppm. This 3-part plant fertilizer delivers all 12 essential micro and macro nutrients, and is pH buffered for ease of use.

Holland Secret Hard Water Micro is designed for ease of use and can be used with any grow medium, in any situation, and at any stage of the grow cycle. With Future Harvest's sediment and urea-free formula, you won't have to worry about clogged lines.

Additional Info

Use all three parts of the Holland Secret 3-Part plant fertilizer together for optimal results. Using only one or two parts, like Grow and Bloom without Micro, could lead to nutrient deficiencies.

For those who do not want to spend money on a lab test, it is advisable to monitor water quality using a nutrient meter. At levels between 200 and 300 PPM, it is advisable to use Hard Water Micro, together with Calnesium, to balance out Calcium levels. Any tap water over 350 PPM should only use Hard Water Micro without Calnesium.
