Product Description

GT Ph Down is an 81% solution of phosphoric acid, used to lower the pH of nutrient solutions. It is reasonably acidic of course and though not really dangerous, pH DOWN should certainly be handled with caution.

Key Features

Growth Technology – great value-for-money additives
Reduces the pH of your nutrient solution
Highly concentrated - 81% Phosphoric Acid
Phosphoric Acid - one of the best and most stable pH down adjusters
Corrosive - requires careful handling

How To Use GT Ph Down

Growth Technology pH Down is 30% phosphoric acid and needs to be handled with care. Just add a little at a time if your nutrient pH is too high in order to lower the pH to the proper level. pH adjustment should be done last after nutrients and additives have been added to the tank. Recirculating systems may need the addition of pH Down every day since the pH of the nutrient solution tends to rise over time.

FAQs

What is Growth Technology pH Down?

Growth Technology pH Down is a concentrated acid solution designed to lower the pH level in hydroponic systems, soil, and coco setups. It ensures optimal nutrient absorption by adjusting the pH of your nutrient solution to the ideal range for plant growth.

How do you use GT pH Down?

To use GT pH Down, add a small amount (a few drops) to your nutrient solution, then mix and test the pH. Gradually adjust until you reach the desired pH level, typically between 5.5 and 6.5 for most plants. Always add pH Down slowly to avoid overcorrection.

Is pH Down safe for plants?

Yes, when used correctly, GT pH Down is safe for plants. It’s specifically formulated to adjust the pH without harming your plants. However, avoid overuse, as drastic pH changes can cause nutrient lockout or stress your plants.

How often should I check pH levels when using GT pH Down?

Check pH levels every time you mix a new nutrient solution and periodically throughout your feeding schedule. Regular monitoring ensures that your plants receive nutrients at optimal efficiency and helps avoid pH imbalances that can hinder growth.

Can I use GT pH Down in organic gardening?

Yes, GT pH Down can be used in organic gardening, but it’s important to apply it carefully. In organic systems, extreme pH changes can disrupt beneficial microbes. Always adjust pH gradually and monitor how your plants and soil respond.

What pH level is best for hydroponics?

For hydroponics, a pH level of 5.5 to 6.5 is typically ideal. GT pH Down helps you achieve and maintain this range, ensuring that nutrients remain soluble and available for plant uptake, leading to healthier and more vigorous growth.

How do I store GT pH Down?

Store GT pH Down in a cool, dry place away from direct sunlight and out of reach of children. Ensure the bottle is tightly sealed to prevent leaks and maintain its potency. Proper storage also extends the shelf life of the product.

Can I use GT pH Down in soil grows?

Yes, GT pH Down is effective in soil grows as well. Adjusting the pH of your watering solution helps maintain soil pH within the ideal range, improving nutrient uptake and overall plant health, especially in more alkaline soils.

Is GT pH Down compatible with other nutrients?

GT pH Down is compatible with most nutrient solutions. However, it’s best to adjust pH after all nutrients have been mixed into your solution, as they can affect pH levels. This approach ensures a stable pH that supports nutrient absorption

Does GT pH Down affect EC (Electrical Conductivity) levels?

GT pH Down minimally affects EC levels, so your primary concern should be pH balance. Focus on achieving the right pH level while monitoring your nutrient solution’s EC separately to maintain an optimal growing environment for your plants.
