Terra Aquatica pH-Down 500ml/1L: Maintain an optimal pH for your plants
Terra Aquatica pH Down ensures precise and long-lasting pH control of your nutrient solutions for maximum nutrient absorption. This expert formulation combines three complementary acids to effectively stabilize your growing environment without residues or disruptions.
Concentrated solution 500ml/1L
Maintenance 5.5 - 6.5
0.5 to 2 ml/L as needed
Hydro, coco, soil
Nitric, phosphoric, and citric acids
No residue, long-lasting stabilization
Triple-action formulation for a stable pH
This less concentrated pH solution revolutionizes acidity control thanks to its unique combination of nitric, phosphoric, and citric acids. Each component works synergistically to neutralize pH fluctuations while naturally regulating excess calcium in hard water. Your plants benefit from a stable root environment that promotes vigorous growth and abundant flowering.
Hydroponic pH regulator without nutrient disruption
Nutrient absorption is instantly optimized when the pH reaches the ideal range of 5.5 to 6.5. This formulation perfectly maintains the nitrogen/potassium ratios of your nutrient solutions without causing over-fertilization. Terra Aquatica liquid pH corrector guarantees long-lasting stability, eliminating the fluctuations responsible for root stress and nutrient deficiencies.
Total versatility for all your substrates
Whether you're growing hydroponically, in coco coir, or in soil, this effective pH regulator adapts to all your needs. Its concentrated formula allows for precise dosing of 0.5 to 2 ml per liter, depending on your water hardness and the type of substrate used. Its residue-free action keeps your equipment clean and maintains the sanitary quality of your grow space.
Additional nutritional benefits
The nitrates and phosphates in this formula provide beneficial nutrients for your plants. Phosphoric acid promotes root development and flower formation, while nitric acid supports vegetative growth. This dual nutritional and regulatory action makes this product an essential ally for optimizing every stage of your indoor crop development.
Professional use and system maintenance
Beyond daily pH regulation, this solution also serves to clean and maintain your growing systems. Its concentrated formula reduces operating costs while guaranteeing consistent, professional results. Horticultural certification ensures maximum safety for successful and worry-free indoor growing.
After 15 years of experience, I always recommend testing the pH of your solution after 30 minutes of mixing for an accurate reading. I add the Terra Aquatica pH regulator drop by drop, stirring between each addition—this method avoids sudden drops that can shock your plants. A little secret: first diluting the pH Down in a glass of water makes it easier to mix evenly in your main reservoir. Joseph – Director of GrowLED.
