Product Description

Since 1996, gardeners in areas with hard water have relied on Holland Secret Hard Water Micro for their plants' nutrition. This formula is specifically designed for water sources with 200PPM (0.4EC) or higher. As a crucial component of the Holland Secret 3-part nutrient system, it provides all necessary micronutrients from seedling to maturity, ensuring strong, healthy growth in hard water conditions. It's a perfect alternative to the standard Holland Secret Micro when dealing with hard water.

Use it in combination with Holland Secret Grow during the vegetative stage, and transition to Holland Secret Bloom as your plants enter the flowering phase. This adjusted trio continues to be the cornerstone of flourishing gardens, now accommodating those with hard water sources.
