There's a very good reason! This stuff is diluted trash. If not just straight up water! Absolute garbage DO NOT BUY! The people that are selling this need to pull on Epstein! The back label of this product is clearly for pH down and not PH up. So that's number one. Number two is that it only has a TDS of 1030. There is no way on Earth that pH up should have a TDS that low. It literally does nothing to the nutrient solution.. this is insane that this product was sold like this for those two reasons. Unbelievable! Apparently Humboldt's Secret is dilution, and ripping people off. This is some S I'd expect meth addicts to do! ## Frequently Bought Together - Humboldts Secret pH Up - Hydroponic pH Up - pH Up for Plants to Stabilize Nutrient - Plant pH Adjustment - Plant Nutrient pH Levels Optimizer (32 Ounce) - Humboldts Secret pH Down | Liquid pH Plant Balancer for Soil & Hydroponics Growing System - Humboldts Secret Set of A & B Liquid Hydroponics Fertilizer - World's Best Nutrient System – Hydroponic Nutrients for Outdoor, Indoor Plants – Supports Vegetative and Flowering Stages of Plants --- ## 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.kg/products/590001911-humboldts-secret-ph-up-for-plants-hydroponics-and-soil-ph](https://www.desertcart.kg/products/590001911-humboldts-secret-ph-up-for-plants-hydroponics-and-soil-ph) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-09-05*
