Review: Great Product - Love this stuff and fast shipping also Review: Works but requires additional grind of sediments. - It works so far but must be filtered and any large pieces ground up using a small blender or mortar-pestal type device. The large pieces otherwise will not dissolve and will jam up pumps. ## Features - Maxigro encourages growth of seedlings, cuttings and stimulates rapid growth through the vegetative growth stage - Maxibloom encourages prolific flowering and fruiting and increases yields and crop quality - Koolbloom is to be used Only at the very end of a plant's life cycle and will help build larger, heavier fruits and flowers ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07DTTLTB1 | | Best Sellers Rank | #109,050 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #2,372 in Garden Fertilizers | | Brand Name | General Hydroponics | | Coverage | 2.2 pounds | | Customer Reviews | 4.7 4.7 out of 5 stars (269) | | Item Form | Powder | | Item Type Name | Fertilizer | | Item Weight | 6.7 Pounds | | Manufacturer | General Hydroponics | | Model Number | GLCMBX0008 | | Specific Uses For Product | Hydroponics | | Target Species | Plants | | UPC | 793094000017 | | Unit Count | 35.2 Ounce | ## Product Details - **Brand:** General Hydroponics - **Item Form:** Powder - **Item Weight:** 6.7 Pounds - **Manufacturer:** General Hydroponics - **Specific Uses For Product:** Hydroponics ## Images ![GLCMBX0008 Maxigro, Maxibloom, Koolbloom Combo, 2.2 Lb Fertilizer - Image 1](https://m.media-amazon.com/images/I/71OYWRJJAYL.jpg) ## Questions & Answers **Q: What is the difference between this and the General Hydroponics Flora combo?** A: There's probably not much difference except liquid vs powder and big mixing ordeal. 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 ### ⭐⭐⭐⭐⭐ Great Product *by S***T on January 13, 2026* Love this stuff and fast shipping also ### ⭐⭐⭐⭐⭐ Works but requires additional grind of sediments. *by B***. on March 13, 2026* It works so far but must be filtered and any large pieces ground up using a small blender or mortar-pestal type device.
