It neutralizes bicarbonate alkalinity in source water, lowers pH, and contributes nitrate nitrogen to the nutrient solution. Account for that nitrogen alongside your base fertilizer rather than treating acid as a nutrient-free input.\u003c\/p\u003e\n\u003ch2\u003eFor hydroponic lettuce and leafy greens\u003c\/h2\u003e\n\u003cp\u003eFor lettuce and leafy-green growers, nitric acid offers a way to manage alkaline makeup water while supplying part of the crop's nitrate-nitrogen requirement. Unlike phosphoric acid, it does not add phosphorus, allowing acid selection to fit the nutrient recipe. Its suitability depends on your water analysis, acid requirement, and total nitrogen target, especially in recirculating systems where repeated additions must be included in nutrient management.\u003c\/p\u003e\n\u003ch2\u003eGuaranteed analysis: 14-0-0\u003c\/h2\u003e\n\u003cp\u003eTotal Nitrogen (N): 14.0%\u003cbr\u003eNitrate Nitrogen: 14.0%\u003cbr\u003eAvailable Phosphate (P₂O₅): 0%\u003cbr\u003eSoluble Potash (K₂O): 0%\u003c\/p\u003e\n\u003cp\u003eDerived from nitric acid.\u003c\/p\u003e\n\u003ch2\u003ePlan acid demand with AlkCalc\u003c\/h2\u003e\n\u003cp\u003eUse the \u003ca href=\"https:\/\/alkcalc.egromobi.com\/\" target=\"_blank\" title=\"Estimate acid requirements and nutrients added to irrigation water\" rel=\"noopener\"\u003eAlkCalc irrigation water acid calculator\u003c\/a\u003e to help estimate the acid required for your water treatment and the nutrients contributed by the acid. Use your source-water alkalinity, treatment volume, desired residual alkalinity, and the correct acid concentration. Include the calculated nitrate-nitrogen contribution in your lettuce or leafy-green fertilizer recipe, then verify the treated water and final nutrient-solution pH with a calibrated meter. Starting pH alone does not establish acid demand.\u003c\/p\u003e\n\u003ch2\u003ePackage sizes\u003c\/h2\u003e\n\u003cp\u003e5 gallon, 1 gallon, and individual 1-quart bottles.

For trained professional users with compatible acid-handling and dosing equipment. Follow the current safety data sheet for protective equipment, storage, dilution, and handling. Always add acid to water, never water to concentrated acid. Do not mix concentrated acid directly with fertilizer concentrates or other chemicals.\u003c\/p\u003e","brand":"BVV","offers":[{"title":"1-quart","offer_id":47850551541844,"sku":"NA67-1QT","price":35.5,"currency_code":"USD","in_stock":true},{"title":"1-gallon","offer_id":47850551574612,"sku":"NA67-1GAL","price":95.0,"currency_code":"USD","in_stock":true},{"title":"5-gallon","offer_id":47850551607380,"sku":"NA67-5GAL","price":335.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0617\/5365\/5380\/files\/custom-hydro-nitric-acid-1-quart-mockup.png?v=1792073872","url":"https:\/\/customhydronutrients.com\/products\/67-nitric-acid","provider":"Custom Hydro","version":"1.0","type":"link"}
