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.

I rarely write reviews for gardening products, but Mykos has genuinely impressed me. Our raised bed is only about 1 foot high and contains nothing fancy; just potting soil and mulch. We do not use any conventional fertilizer. The only amendment we've consistently added is Mykos, and it has made a remarkable difference in our garden. I first learned about mycorrhizae during an indoor gardening class and spent some time researching the science behind it before purchasing this product. Based on our experience, it has been well worth it. We backyard garden in USDA Zone 8–9, where the native soil is rocky and spring-planted vegetables often require frequent watering to survive. Even under these conditions, our plants have been thriving. Some have become so vigorous that they are bushier and spreading much more than expected. One of the biggest surprises has been root development. I'm sharing photos of the strong sunflower roots from our raised bed because they clearly show the difference I've observed. Last year, I struggled to keep dill alive, but this year it has been growing beautifully. Spinach was another challenge for us,seedlings would often remain weak and fail to establish. A timely addition of Mykos helped them recover and grow much more vigorously. I prefer using the granular form. Whenever I transplant a seedling or sapling, I dig the planting hole, add roughly 5 cc of Mykos directly where the roots will make contact, plant, and then water thoroughly. I've also used it successfully when growing plants from seed. While every garden is different, Mykos has become a permanent part of my gardening routine. For anyone looking to improve root development and plant vigor, especially in raised beds, this product is definitely worth considering.

Great value for the price point. I see lots of people claiming to see results in 2-3 days which is totally false. Don’t get me wrong this stuff works amazing but mycorrhizal fungi don’t work that fast it takes 1-3 days for them to start to spread but you truly won’t see the affects until at least 4 weeks. Everybody claiming it works in a few days are just seeing the results of then actually taking care of their plant. I only use it for transplants and I gently rinse most of the soil off the roots and then completely coat the roots in it. After that I take my mister and make sure I mist it all to make sure everything’s moist. Then I replant in the new pot or in ground and give my plants a good drink of water. I typically see results, like actual results from the product in 4-6 weeks, but the fungi will start spreading with the first few days. It’ll create a symbiotic relationship with your plants roots and allow it to take in my nutrients micro and macro and also take up water which other plants without the fungi wouldn’t be able to take up. This stuff truly is amazing but don’t expect anything drastic in the first week it’s just not how it works at all but beneath the soil it’s already doing work just not enough to cause changes right away with your plants. I grow indoor and outdoor all year round and it’s also what we use on our 36 acres fruit/veggie farm. I personally go through about 3 bags a year but it lasts awhile if you don’t have a large garden/indoor grow all year round. A few of the other local farmers near me have also switched over to this brand which they previously used the Trifecta Myco Supreme which is also amazing and typically works a bit faster than Mykos because it’s a powder and not granules but it’s way more money for a lot less product. I recommend this to literally everybody I cross paths with that gardens/farms. So if you’re on the fence about this, this is your sign to hop on the Mykos wagon and hook your roots up in a (symbiotic) relationship. Your fruits, veggies,house plants, herbs, and even your devils lettuce plants will thank you 10 fold.

Best stuff on the market in my opinion. No complaints what so ever. Does exactly what it is supposed to do. You don't need much for each plant. It goes a long way and helps plant's roots tremendously. Very small granules that will dissolve after a few waterings. Priced well compared to other brands. This stuff has my vote.

Well, I've inoculated all the houseplants and my vegetable seedlings. Now the waiting game. First impressions are; decent resealable package, comes with a scoop. The granules are odd... the fungus certainly isn't that large so I'm not exactly sure what it is, perhaps a vessel for the fungal spores. My initial shipment got lost in transit somehow. Replacement took 3 weeks on top of original wait time after purchase order. That part was disappointing. Edit- after using it I had some left over so I did a few different side by sides. Plants (I used daisy) treated with this did have larger roots and more white hairs on them than the control group, however, the difference was much more pronounced at 6 months in and 1 year in than my 2 week, 1 month, 2 months, and 3 months growth pots. Now I'm out of experiment plants but I think it's clear that this stuff works.
