Description
Advanced Nutrients pH Down (1 Litre) is a high-concentration, pharmaceutical-grade phosphoric acid formula designed to safely lower the pH in hydroponic systems, coco coir, soil, and sphagnum moss. It ensures optimal nutrient uptake for plants, preventing nutrient lockout and boosting growth.
In many cases, there’s a hidden problem that blocks plants from absorbing nutrients.
The problem involves what chemists call “pH”. pH term describes the relative alkalinity and acidity of the water and root zone media your plants grow with.
If you want your hydroponics plants to grow quickly and produce fantastic harvests time after time, you need to carefully balance the pH of your hydroponics root zone and nutrient water.
- Promotes Plant Health and Nutrient Absorption
- Superior-grade, Pure Formula
- Economical and Easy to Use
You’ve got to be a bit of a chemist to do this, and you’ve got to use Advanced Nutrients pH Up and pH Down to carefully regulate pH levels so plants absorb maximum nutrients and grow well.
DIRECTIONS:
Use small amounts when adjusting the nutrient solution to affect the pH level, as required. Use to maintain the optimum pH level of 5.5 to 5.8 for hydroponics and 6.2 to 6.3 for sphagnum moss and plants in containers. For best results, check the pH level daily.
Conversions: 1 Teaspoon = 5mL | 1 Tablespoon = 15 mL | 1 Ounce = 30mL | 1 Cup = 240 mL
- Highly Concentrated: A small amount significantly reduces pH levels, making it economical.
- Pharmaceutical Grade: Contains high-quality phosphoric acid for consistent, safe, and effective pH adjustment.
- Versatile: Suitable for all hydroponic systems, coco coir, soil, and aeroponics.
- Ideal for Growth: Helps maintain the ideal range of 5.5–6.3 for maximum nutrient uptake.
Usage Tips
- Use Sparingly: Because it is highly concentrated, start with small amounts (e.g., 10 mL per gallon) and test frequently.
- Compatible: Works well with all Advanced Nutrients products and other nutrient brands.
- Safety: Always wear protective gloves and eyewear as it is a corrosive, acidic product.
