H&G pH+ Stabil/Osmose
H&G pH+ Stabil/Osmose is a professional-grade pH adjuster and stabiliser formulated specifically for growers using reverse osmosis (RO) water or very soft water sources. These water types often lack carbonate hardness, making them prone to rapid pH fluctuations once nutrients are added. This product not only raises pH but also replenishes essential carbonates to create a reliable buffer, ensuring a stable pH range for up to 10 days. This stability is vital for consistent nutrient uptake, preventing deficiencies, and supporting optimal plant growth.
The formula helps protect plants from nutrient lockout caused by unstable pH and improves overall solution performance in hydroponic, coco, and soil systems. It is particularly beneficial for growers running recirculating systems or long-term reservoirs, where maintaining a steady pH is critical. By restoring balance to RO or soft water, pH+ Stabil/Osmose creates a dependable foundation for any nutrient program and reduces the frequency of manual pH adjustments.
