House & Garden pH Stabiliser is designed to maintain a stable pH in hydroponic systems, especially when using reverse osmosis (RO), rainwater, or other soft water sources. It adds essential carbonates that regulate cation exchange, ensuring your A/B nutrients are absorbed effectively. Ideal for use in recirculating systems, this stabiliser helps avoid pH fluctuations for up to 10 days, promoting consistent nutrient uptake, better plant health, and increased yields. By harmonising with your base nutrient, it eliminates the guesswork and stress of constant pH monitoring, making it an essential for growers seeking efficiency and reliability.
