Thank you! ### ⭐⭐⭐⭐⭐ Top of the Line *by N***R on July 26, 2026* Works great on plants…. Exactly what they need ### ⭐⭐⭐⭐⭐ Fantastic calmag *by J***Y on October 27, 2024* I love that this has about 2x the amount of calcium of any other one on the market. I have looked around a lot but I dont know everything about it but I been growing for over 12 years and this is the best calmag I have used yet. Yes it smells like vinegar but how else are you going to get organic calmag? Idk about anybody else but organic growing stinks to me I can smell it no doubt. If you dont like synthetic then you better get used to the smell or use some synthetic that says its organic. I just know that this makes my plants extremely happy and I will be using this for as long as they sell it. ## Frequently Bought Together - TPS NUTRIENTS Organic Cal-Mag OAC Plant Nutrient and Supplement, Plus Iron and Micronutrients 1 Quart (32 oz) - TPS NUTRIENTS Silica Gold Plant Strength Nutrient and Supplement with Bioavailable Silicon 1 Quart (32 oz) - Signal Terpene Enhancer Plant Nutrient and Supplement, Flower Hardener and Increases Flavor by TPS Nutrients, 1 Quart (32 oz) --- ## 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.co.za/products/86608805-tps-nutrients-organic-cal-mag-oac-plant-supplement-1-quart](https://www.desertcart.co.za/products/86608805-tps-nutrients-organic-cal-mag-oac-plant-supplement-1-quart) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-08-31*
