Fast & Gentle Correction

pH Down quickly and effectively corrects alkalinity levels in growing media and nutrient solutions. If the pH becomes too high, a small amount of pH Down can restore the balance within seconds.


No Stress To Plants

pH Down utilises a weak acid to gently bring the pH levels to their appropriate range. Unlike stronger solutions, pH Down is root-friendly and does not cause stress to plants or disrupt the surrounding micro-life.


Ensures Nutrient Availability

Excessively high pH levels can prevent plants from accessing essential nutrients, leading to stunted growth, yellowing, and increased vulnerability to pests and diseases. pH Down helps maintain an optimal pH range, ensuring that plants can efficiently absorb the nutrients they need.


Super Easy To Use

Apply pH Down in small amounts at a time, stirring thoroughly and taking pH readings after each application until the desired acidity level is reached. The ideal pH range for most hydroponically grown plants is between 5.5 and 6.5.


Safety Precautions

It is crucial to take extreme caution when using pH Down, as it can cause severe skin burns and eye damage. It is recommended to wear appropriate protective equipment, such as gloves, an apron, splash goggles, and a vapour respirator. Additionally, pH Down may be corrosive to metals, so it should be stored in a cool, dry place away from direct sunlight.


Where To Use pH Down

pH Down is suitable for use in any growing media where the pH level is too high (alkaline). It can be identified by pH readings above 6.5 or by observing symptoms such as dark spots, yellowing, curling, or leaf necrosis on plants. Mix pH Down into your regular nutrient solution and apply it during your usual watering routine.

pH Down is a premium pH acidifier that provides an effective solution for correcting alkaline pH levels. It restores pH balance in seconds without causing stress to plants or disrupting the surrounding microbial life. Only a small amount of pH Down is needed to achieve the desired pH level.

When using Emerald Harvest pH Down, it is important to follow the instructions provided by the manufacturer and take appropriate safety measures to protect yourself and your plants.
