Description

Mykos is a fast-growing, beneficial fungi that connects many of the eneficial microbes in the soil to host plants. This "symbiotic" relationship inceases the supply of nutrients to plants, increasing the availability of both moisture and most of the fundamental elements required for plant growth. This greater nutrient availability leads to a bounty of healthier bigger plants and "Bumper Crops" Mykos has been used to produce world record-breaking pumpkins every year since 2006.

    • Xtreme Gardening RTI RT4402 Mykos Review (2.2-Pound Bag)
Xtreme Gardening Mykos is a highly effective mycorrhizal inoculant that helps improve root growth, nutrient uptake, and overall plant health. Containing pure Rhizophagus intraradices, it enhances the symbiotic relationship between roots and beneficial fungi, leading to stronger, more resilient plants. The product is easy to use—just mix it into the soil or apply directly to roots during transplanting. Many growers report faster root development, increased yields, and improved drought resistance.

Pros: ✔ 100% natural with no additives ✔ Promotes rapid root growth and nutrient absorption ✔ Improves plant resilience to stress and drought ✔ Easy to apply and works with various plants Cons: ✖ Takes time to see full benefits ✖ Slightly more expensive than synthetic alternatives If you want to boost plant growth naturally, Xtreme Gardening Mykos is an excellent investment.

    • The BEST!
Review Image by Sarah Loutch Sarah Loutch
I don't know what this stuff is exactly - or how it works - but it's the best thing I've ever done for my plants! The difference in growth is insane! Before, when I'd transplant anything, there was a 50/50 chance it was a gonner due to transplant shock, etc. Now? I have a 99% success rate every time as long as I use this! I use it in EVERYTHING now! I even made a liquid out of it to water my plants (as an experiment) and it worked great! Hands down, best planty item I've purchased. I'd give it 10 stars if I could! ... show more

    • This product works very good.
I use this product for my rooted clones, and there is a huge difference in how fast and healthy they grow.. I started using it for my bigger plants that I transplant as well and noticed they also grow faster and healthier. This product is intended to be directly applied to the root ball so I saturate it then apply the granules so they stick during transplant. ... show more

    • Amazing for flower plugs
I am a small-scale urban flower farmer and I often order plugs to get a head start on the season. It takes them a little while to root down and I tried this to see if it would help. It was amazing. The plugs that had the stimulator rooted down quicker and more vigorously than the ones that did not! Definitely recommend. ... show more

    • Improved Overall Plant Systems
I have used Mykos for the past three year as it was highly recommended for healthy root development of plants by organic gardeners. My vegetable garden has become more productive than it has ever been in the past. I start my seeds indoors using a seed starting mixture in net pots (for air pruning the roots) instead or plastic cell containers. Once my seeds germinate, I moved them under grow lights which are just shop light fixtures with one red (warm white) and one blue (cool white) fluorescent bulbs to provide more light contained in the natural light spectrum of the sun. When my plants develop their first set of true leaves I began a weekly feeding of Neptune's Harvest fertilizer at a 50% strength as the seedlings were still tender. The plants are hardened off in a simple greenhouse. The soil is amended with Azomite and wormcastings. We sprinkle Mykos on the plant roots as they are placed in the ground. The Mykos helps to create a vast root system which allows the plant to absorb more moisture and nutrients from the soil. As a result, plans are healthier and able to produce a more abundant crop. We have also planted over one hundred shrubs and trees using Mykos. With a healthy root system in place before the weather turns cold, our plants are better able to survive the bitterly cold Minnesota winters. We have experienced almost no winter loss after switching to this method. I am amazed at the growth my plants have experienced as a result and would highly recommend this method. We will definitely continue to use this product as we have experience the difference it has made in our plants. ... show more
