This is an excellent product and we re-order twice a year how they recommend this. ### ⭐⭐⭐⭐⭐ Leafy green plants LOVE this. *by C***N on January 12, 2026* If you have any yellowing of green leaves or any unhappy plant, this stuff is sure to revive them. It may seem pricey but you only need a little bit in your watering can. It really makes a huge difference to the happiness of your plants. I highly recommend it. ### ⭐⭐⭐⭐⭐ CaMg+, BioThrive, BioThrive!! The must have combination for excellent growth *by C***G on December 4, 2016* This is a must have for anyone serious about their plants development and care about using only organic nutrients. General Organics sells way too many products and some of which are trivial for the plant growth (I have tested with several rounds of growth). After about eleven successful batches with an average of 5 plants each time, I have really narrowed it down to the essential nutrients which actually make a difference. The CaMg+ is a must along with the BioThrive Growth (for vegetative and Bloom for flowering stage) and the Bio Root. To supplement the other micro nutrients I use Golden Tree, I must say that this combination is extremely successful and there is no need to use all of the products in the series. My plants are extremely perky with strong roots and you can see it in their daily growth. Highly recommended. ## Frequently Bought Together - General Hydroponics CaMg+, Calcium Magnesium Supplement, Quart - General Organics BioThrive Grow, Plant Food, 4-3-3, 1 qt. - General Organics BioRoot, Plant Food for the Roots, 0-1-1, 1 qt. --- ## 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.is/products/6354014-general-hydroponics-gh5312-camg-plant-nutrition-quart](https://www.desertcart.is/products/6354014-general-hydroponics-gh5312-camg-plant-nutrition-quart) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-07-06*
