I only used Maxigro on all my veggies in coco, soil and Kratky. Maxigro did very well when I adjusted dose as plants progressed. I used faucet water with a 24 hr leaching process and the only leaf discoloration was on my cucumis sativa but that's not unusual. I got male and female flowers with just Maxigrow, no bloom. grew indoors under 2300lum/5000kel LEDs. I did a lot of research since it was my first grow but here's a great YouTube comparison done by Khang Starr. Maxigro did great on all accounts including algae grow. https://youtu.be/5YHSRLG5YGQ **Q: will this dissolve in cold water?** A: Yes, it dissolves readily in cold water. **Q: Come with feed chart?** A: No. The website has the feed charts. There can be some trouble accessing the chart if you have an agressive fire wall. **Q: Can it be used in a soiless media?** A: Yes, we use it for the Kratky method. Check out YouTube for this easy and inexpensive soiless grow method. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Recommended *by S***Z on May 2, 2026* Works well! ### ⭐⭐⭐⭐⭐ 👍 Maxi series *by R***D on October 30, 2025* They really seem to provide the nutrients fast the packages come sealed easily sized to store general hydroponics is always the best quality and 👍 I like this series so far ### ⭐⭐⭐⭐⭐ Easy to use *by D***N on December 8, 2025* Simple and effective nutrients ## Frequently Bought Together - General Hydroponics GLCMBX0008 Maxigro, Maxibloom, Koolbloom Combo, 2.2 Lb Fertilizer - General Hydroponics CALiMAGic 1-0-0, Concentrated Blend of Calcium & Magnesium, Secondary Nutrient Deficiencies Helps Prevent Blossom End Rot & Tip Burn, Clean, Soluble, 1-Quart - General Hydroponics pH Control Kit For A Balanced Nutrient Solution --- ## 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.be/products/68483960-general-hydroponics-glcmbx0008-maxigro-maxibloom-koolbloom-combo-2-2-lb](https://www.desertcart.be/products/68483960-general-hydroponics-glcmbx0008-maxigro-maxibloom-koolbloom-combo-2-2-lb) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-08-06*
