Advanced Nutrients pH UP

Say goodbye to nutrient lockout and hello to heavier harvests. Advanced Nutrient’s scientists engineered pH-Up with potassium hydroxide and pH-Down with Phosphoric Acid, so you can easily achieve the ideal pH levels for optimal nutrient absorption. We’ve developed these highly stable buffers to give you precise control over your pH, even after dilution or adjustments between reservoir changes.

  • Recalibrate pH levels with maximum buffers
  • Highly concentrated formulas for longer use

The Critical Key to Healthy Plants:

Have you ever met a grower who fed his crops the best nutrients and they still gave him weak performance and small harvests? 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. 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.

Get yourself a pH meter and read your root zone and nutrient water daily if you’re using rockwool, volcanic rock, coco coir, soil, sphagnum moss, aeroponics, or other types of root zone media. You’ll usually find that pH needs to be adjusted. Guess what? If you don’t adjust pH to optimum levels, your plants will grow slowly, produce teeny-weeny harvests, or even die. If you use pH adjustment products made by other companies, you may damage your plants, or you may not be able to do precision adjustment of pH.

Guaranteed Analysis:

Soluble Potash (K2O)………………………………….38%

Derived From: Potassium hydroxide

How to Use:

  • Nutrient Solutions: Mix a new réservoir weekly.
  • Coco: Daily.
  • Other Substrates: 2-4 times/week as necessary.

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.

pH-Up & pH-Down is specially designed for use with diverse hydroponic growing media and all continuous liquid-feed growing systems such as aeroponics, drip irrigation and emitters, NFT, flood and drain, and deep water culture.
