Review: Awesome Product! Definite Purchase Again! - Humbolts Myco Maddness is a product I've used for years and I personally would not do without it, In my Opinion this product out Performs almost all the ecto and endo rooting products I've tried in the past 8 years! Thank U "Humbolt Nutrients" for This Awesome Product! My only complaint it's a little Pricey but worth Its Cost In Gold! Review: Amazing Results - Performed side by side tests last year with Japanese Maple Tree seedlings, half treated with Humboldt Nutrients MycoMadness, the other half without. Everything else; water, sun and other supplements were the same. Results: those treated were about twice as large as those not treated. No more testing, I bought a pound this year and will treat all of the plants with it. Pros: It works better than expected. Cons: Expensive, but you get what you pay for, and a little goes a long way when properly mixed with water. ## Features - Myco madness is a soluble powder which contains a biologically active package - It contains mycorrhizal fungi that colonize plant roots and extend the root system into the surrounding media - It can help in forming an essential link between the plant roots, organic matter and fertilizers of all types - Myco madness can help plants improve nutrient and water uptake for superior plant performance - It greatly enhancing the absorptive surface area of root systems - Not sold in HI ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B007QVAYJ8 | | Brand Name | Humboldt Nutrients | | Coverage | Medium | | Customer Reviews | 4.2 4.2 out of 5 stars (21) | | Global Trade Identification Number | 00837654466933 | | Item Form | Powder | | Item Type Name | 8-Ounce Humboldt MycoMadness Nutrient | | Item Weight | 0.1 Pounds | | Manufacturer | Sunlight Supply Inc. | | Model Number | HNMMA405 | | Specific Uses For Product | Organic | | UPC | 837654466933 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Humboldt Nutrients - **Global Trade Identification Number:** 00837654466933 - **Item Form:** Powder - **Item Weight:** 0.1 Pounds - **Specific Uses For Product:** Organic ## Images ![Humboldt Nutrients HNMMA405 8-Ounce Humboldt MycoMadness Nutrient - Image 1](https://m.media-amazon.com/images/I/6118oJa2kCL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Awesome Product!
