It’s especially effective for quick adjustments when you’re working with standard setups. However, if you’re using tap water or have an organic system (I use bacillus along with some other beneficials for root rot), this might not be your best bet. The product’s effectiveness tends to wane faster under these conditions. The reason? It’s primarily citric acid-based, which organisms can metabolize quickly. This means it loses its pH-lowering power sooner than you might expect, leading to potential fluctuations in your system. For more stable pH control in organic setups, consider switching to a phosphorus-based pH down. This type will generally maintain its effects longer, keeping your garden’s acidity levels more consistent. Review: Good mild ph down - It’s a good citric acid based ph down. It is on the mild side in terms of concentration. I have hard water with a high ph and it takes quite a bit of it get a drop in ph. ## Features - Foxfarm Cultivation Nation PH Down ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08KWPB8KR | | Brand | Fox Farm | | Brand Name | Fox Farm | | Coverage | Medium | | Customer Reviews | 4.5 out of 5 stars 471 Reviews | | Global Trade Identification Number | 00752289270147 | | Included Components | B08KWPB8KR | | Item Form | Liquid | | Item Weight | 32 Ounces | | Item form | Liquid | | Item weight | 32 Ounces | | Liquid Volume | 1 Quarts | | Liquid volume | 1 Quarts | | Manufacturer | Fox Farm | | Model Number | 5039072 | | Number of Items | 1 | | Part Number | 5039072 | | Specific Uses For Product | Hydroponic | | Specific uses for product | Hydroponic | | UPC | 752289270147 | | Unit Count | 32 Milliliters | ## Product Details - **Brand:** Fox Farm - **Item form:** Liquid - **Item weight:** 32 Ounces - **Liquid volume:** 1 Quarts - **Specific uses for product:** Hydroponic ## Images ![Fox Farm Cultivation Nation PH Down - 1 Qt. - Image 1](https://m.media-amazon.com/images/I/71tq2-s34WL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Effective but fleeting *by J***N on 10 July 2024* I’ve been using Fox Farm pH Down to manage the acidity in my hydroponic garden, and a little truly goes a long way.

It is on the mild side in terms of concentration. I have hard water with a high ph and it takes quite a bit of it get a drop in ph. ### ⭐⭐⭐⭐⭐ Best product on the market *by J***N on 4 March 2025* Fox Farm hands down makes the best grow products out there. This stuff is so potent. My tap water comes out around 7-8 ph, and I want 6. I have a 6L hydro system and only need 1/8th of a tsp of this, which actually brings it down to 4 ph. I thought my PH tester was broken so I bought a new one, and it gave the same readings. ## Frequently Bought Together - FoxFarm Cultivation Nation pH Down - Liquid Nutrient Solution Adjuster for Hydroponic & Soil Gardens, Lowers pH Levels - 40% Citric Acid for Optimal Plant Growth (Quart) - FoxFarm Cultivation Nation pH Up - Liquid Nutrient Solution Adjuster, Raises pH Levels for Hydroponic & Soil Gardens - Formulated with Potassium Hydroxide for Optimal Growth (Quart) - FoxFarm Fertilizer Soil Trio Liquid Nutrient: Tiger Bloom, Grow Big, Big Bloom Bottles - (Pack of 3-1 Pint) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ni/products/380656122-fox-farm-cultivation-nation-ph-down-1-qt](https://www.desertcart.ni/products/380656122-fox-farm-cultivation-nation-ph-down-1-qt) --- *Product available on Desertcart Nicaragua* *Store origin: NI* *Last updated: 2026-10-18*
