NH pH Down Nitrogen Base – pH Control for Healthy, Vigorous Plant Growth
WHAT IS IT?
NH pH Down Nitrogen Base is a premium pH control additive designed to lower the pH of your nutrient solution, ensuring plants receive nutrients in their most available form. Ideal for all crops—including lettuce, leafy greens, fruiting plants, and ornamentals—this nitrogen-based formula not only corrects pH but also provides an essential macronutrient that supports lush foliage, strong stems, and efficient photosynthesis. Perfect for hydroponic systems such as Kratky, NFT, DWC, aeroponics, drip irrigation, and sprinklers, it helps maintain consistent pH for healthier plants and higher yields.
WHY YOU NEED THIS PRODUCT
• ✅ Maintains the ideal pH range (5.5–6.5) for maximum nutrient absorption
• ✅ Supplies nitrogen to encourage greener, more vigorous plant growth
• ✅ Reduces risk of nutrient lockout, algae growth, and poor uptake
• ✅ Safe and effective for all plant stages, from seedlings to harvest
HOW TO USE
Dilution: Add a few drops of NH pH Down Nitrogen Base to your water or nutrient solution, mix thoroughly, then measure pH.
Application: Repeat in small increments until your desired pH is reached. Always adjust pH last after adding all nutrients.
