It prepares the substrate before cultivation by saturating its cation exchange sites with calcium and magnesium, thereby preventing unwanted pH fluctuations in the root zone and ensuring a stable growing base from the very first watering.\u003c\/p\u003e\n\n\u003ch2\u003ePrepares and buffers coconut coir\u003c\/h2\u003e\n\u003cp\u003eUntreated coconut coir tends to capture calcium and magnesium from the nutrient solution, causing deficiencies in the plant and pH imbalances. Substrate Buffer Liquid fills these exchange sites with Ca and Mg, so the coco becomes “buffered” and no longer steals these elements from the feed, leaving them fully available to the roots.\u003c\/p\u003e\n\n\u003ch2\u003eStabilizes pH in the root zone\u003c\/h2\u003e\n\u003cp\u003eBy saturating the substrate’s exchange capacity, the product acts as a buffer that softens sharp rises and drops in pH. This results in more consistent nutrient uptake, a healthier root system, and a crop that is more resistant to stress.\u003c\/p\u003e\n\n\u003ch2\u003eCompatible with all substrates\u003c\/h2\u003e\n\u003cp\u003eAlthough its use is especially recommended in coco, Substrate Buffer Liquid can also be used in soil, mixes, and inert substrates to homogenize the starting pH and improve the efficiency of Aptus’s feeding program.\u003c\/p\u003e\n\n\u003ch2\u003eDirections for use\u003c\/h2\u003e\n\u003cp\u003eDilute in the irrigation water according to the dosage table and apply to the substrate before starting cultivation to pre-treat it.
