DYNOMYCO® is the product of thirty years of Israeli research. The species and strains that make up its active ingredients were carefully screened specifically for cannabis. Glomus intraradices and Glomus mosseae, the active ingredients in DYNOMYCO® mycorrhizal inoculants, are naturally-occurring arbuscular mycorrhizal fungi (AMF) that have been identified and well-researched as powerful and effective plant symbionts that enhance nutrient uptake and water absorption and protect plants against various types of stress. DYNOMYCO® contains an especially vigorous strain of Glomus intraradices that was originally isolated from the harsh conditions of the Israeli Negev desert, along with additional strains of Glomus intraradices and Glomus mosseae from other territories, to ensure quick acclimation to other soil and media types and climates.
The combination of these two species of mycorrhizal fungi provide the following benefits to plants:
• Increased Phosphorus (P) uptake
• Increased Nitrogen (N) uptake
• Increased micro-nutrient uptake
• Improved plant establishment
• Increased flowering
• Increased crop yields
• Drought protection
• Drought tolerance
• Healthier root systems
• Disease suppression
• Salinity tolerance
No! DYNOMYCO® contains only naturally-occurring (non-GMO) fungi. Based on over 400 million years of evolution, natural mycorrhizal fungi are already well-adapted to help 90% of all plant species, without the need for any genetic modification. We’ve selected and screened the strains of fungi we use to optimize cannabis cultivation without any need of modifying or altering them. DYNOMYCO® is as natural as it gets and is Clean Green Certified!
Not all mycorrhizal inoculants are created equally! Our unique production process results in a premium mycorrhizal inoculant, which truly stands out among the competition:
• DYNOMYCO® mycorrhizal inoculants are highly-concentrated. When it comes to mycorrhizae, the cost/benefit of an inoculant is mostly dependent upon product concentration. DYNOMYCO® products contain 900 viable propagules per gram of Glomus intraradices and Glomus mosseae, two endomycorrhizal fungi proven to have a symbiotic relationships with cannabis (see question, “What types of mycorrhizal fungi are in DYNOMYCO®”).
• DYNOMYCO® contains vigorous strains of endomycorrhiza, sourced from the harsh Israeli desert. These fungal strains have evolved to be true survivors, able to adapt and thrive in the most difficult conditions (high salinity, pH levels, droughts, etc.).
• DYNOMYCO® does not contain any ectomycorrhizal fungi, which do not associate with cannabis plants at all! (see question, “What is the difference between endomycorrhizae and ectomycorrhizae”).
• DYNOMYCO® contains only naturally-occurring fungi (non-GMO).
• DYNOMYCO® is based on whole inoculum, i.e. it contains spores, hyphae and root fragments, which support quick plant colonization. These propagules are grown in-vivo (on living plants) to best resemble natural conditions, thus they are more resilient and more tolerant compared to sterile, lab produced spores.
• DYNOMYCO® is produced in-house and not outsourced like many other products on the market. DYNOMYCO® is the result of 30 years of Israeli research, and hundreds of field trials worldwide. We’ve worked with medical cannabis growers in Israel and both medical and recreational growers in the USA to best understand the plant-fungal interaction and to screen which species and strains work best and are most effective.
Endomycorrhizal fungi, otherwise known as arbuscular mycorrhizal fungi (AMF), physically penetrate the cortical cells of plant roots, thus directly availing the plant with nutrients. Ectomycorrhizal fungi typically do not penetrate the plant root, but rather wrap around the root tips. Endomycorrhizae occur in 90% of all vascular plant species and are especially relevant in the initial stages of plant growth. Ectomycorrhizae are only relevant for 10% of vascular plants, mostly trees and woody plants such as birch, eucalyptus, oak, pine and other hardwood trees and contribute to later plant growth stages in those plants. Ectomycorrhizal fungi do not form symbiotic relationships with cannabis at all, and adding it to your growing operation will not help your plants absorb more nutrients or water!
It is difficult to know specifics regarding natural mycorrhizal fungi already in the soil without specialized testing which describes the species, amounts and ratios, as well as how far away the most beneficial mycorrhizal fungi are from the roots of your plants. These uncertainties may delay the formation of mycorrhizae with the plant roots and cause your plants to miss critical benefits during this time. In addition, there is no guarantee that the mycorrhizal fungi in your native soil have symbiotic relationships with cannabis. The fungi in DYNOMYCO® have proven symbiotic relationships with cannabis and are the best way to guarantee inoculation.
The sooner mycorrhizae form, the sooner they start to benefit plants, and as any grower knows, the first days of the plant’s life cycle can be critical to success. When growing cannabis it is imperative to get the plants off to the best start possible; with short life cycles of only a few months, cannabis plants need all the help they can get at an early stage so that they can focus on flowering rather than vegetative growth.
DYNOMYCO® has a two year shelf life at the concentrations stated on the label. After two years degradation of the fungi may occur. Each product has a “best if used by” date on the packaging.
DYNOMYCO® needs to make direct contact with the roots of your plants in order to be most effective. It can be applied by either mixing it into the growing media, applying it in the planting hole or as a root-ball coating. Therefore, it is best to apply directly to seedlings and clones and at every transplantation into larger containers. The standard rate of application is 5 grams per seedling/clone and from there 5 grams of DYNOMYCO® for every gallon of soil (1.25 grams per liter). See product label for more detailed instructions. Otherwise, application of DYNOMYCO® mycorrhizal inoculants changes almost nothing else in your cultivation process.
No! However, we wouldn’t want good product to go to waste. Please be advised of DYNOMYCO®’s recommended application rates (see answer to question above: “When is it good to apply DYNOMYCO® and how much?”), but don’t worry about over-application, as the plant autoregulates its mycorrhization and limits the fungi to the ideal rate.
DYNOMYCO® should be reapplied with every grow cycle, since mycorrhizae generally survive only as long as their host plants. If you are using new growing media, then adding DYNOMYCO® is a necessity as the new soil will not have much microbial life in it. If planting in reused soil, you want to inoculate the soil again in order to let the plant begin its life with fungi to help out in the early stages of growth. DYNOMYCO® should be reapplied with each transplantation into larger containers. This is to ensure that the newly formed root tips will also enjoy the benefits of mycorrhizae.
Depending on the growing protocol and operation, effective DYNOMYCO® inoculation will likely become apparent within two to six weeks (though we have even seen improvements within just a few days). Visual differences may include faster plant growth, larger flowers, richer plant color, more lush and dark, healthier leaves, more potent scent, bushier looking plants and fewer signs of stress in comparison to non-inoculated plants. Other differences may include a healthier root system and root structure (noticeable when transplanting), as well as reduced transplant shock.
We recommend asking us before using fungicides together with DYNOMYCO® inoculants. As a rule of thumb, non-systemic fungicides, herbicides and insecticides are generally compatible with DYNOMYCO® inoculants, while many systemic fungicides are incompatible. When drenching soil with fungicide, we recommend doing so at least two weeks prior to inoculation or at least four weeks after planting. To ensure compatibility with other treatments, please check DYNOMYCO®’s Compatibility Tool. When in doubt, our technical staff is always available to help. In general, we recommend not using synthetic pesticides or fungicides – there are lots of natural products that will have the same effect and that are better for both you and your plant’s health. We support organic and natural farming practices, especially when it comes to cannabis which is often provided to medical patients.
The endomycorrhizal species Glomus intraradices, which is one of the active ingredients in DYNOMYCO®, is considered the “universal soldier of mycorrhiza”, as it exhibits relatively little host specificity and thus will benefit most plants. However, certain soil and growing media conditions may enhance plant responsiveness to DYNOMYCO® and the two species of fungi. Certain unfavorable soil conditions may promote the effectiveness of DYNOMYCO® such as low water and organic matter content, deficient soil phosphorus and nitrogen levels, heavy metal toxicity, and acidic or alkaline soil conditions. Sub-optimal soil acidity conditions limit crop production in 40% of the world’s soils, mostly because many plants do not absorb nutrients (especially phosphorus) well in acidic (pH < 5.0) or in alkaline (pH > 7.5) soils. Glomus intraradices adjusts soil pH levels in order for plants to better absorb nutrients, while Glomus mosseae promotes disease suppression and keeps root systems healthier. Each one of the fungal strains were selected for traits and qualities that help cannabis grow optimally in various growing media. Certain plant families are considered non-mycotrophs, and do not form symbiotic relationships with mycorrhizal fungi, such as the fungi in DYNOMYCO®. These include mostly brassicae (kale, broccoli, spinach, cauliflower, etc.)
High rates of fertilizers, especially inorganic and soluble phosphorus fertilizers, can hinder the formation of mycorrhizae. Mycorrhizal fungi are sensitive to soil phosphorus levels because if there is already a surplus of phosphorous available to the plant, mycorrhizae have less reason to perform. High phosphorus contents will therefore also cause the mycorrhizae to be delayed or not perform other important duties such as increasing water and other nutrient uptake into the plant. Available phosphorus levels should be kept in the low to moderate range per soil type, especially at the time of mycorrhizal inoculation (when the mycorrhizae attach to the plant roots). However, organic forms of fertilizers have been shown to have less inhibitory effects on mycorrhizae than inorganic, soluble fertilizers. The use of organic fertilizers, kelp, humic acids and other carbon sources have been shown to be suitable when combined with mycorrhizal fungi. Composts are mostly compatible with mycorrhizal fungi, but caution should be taken as some compost sources may have high salt or other nutrient content that can inhibit DYNOMYCO®’s mycorrhizal fungi.
DYNOMYCO® mycorrhizal inoculant must be put in direct contact with inoculable roots, which is easier to do during the seeding, cloning, planting and transplanting stages. However, if mature plants show signs of stress, then an application of DYNOMYCO® by root-ball dusting or transplanting into a new pot with inoculated soil can help greatly. An additional way of applying DYNOMYCO® to established plants is to poke 4-5 holes around the plant, making sure that the holes are deep enough to reach the roots (this can vary depending on the size and depth of the pot or soil), and use a funnel to pour DYNOMYCO® into each one of the holes. Make sure DYNOMYCO® gets to the youngest roots, which are at the bottom, as these are softest and easiest for the fungi to penetrate (older roots harden up as they mature, becoming impenetrable).
Absolutely! We are strong supporters of natural farming practices which are mostly compatible and even complementary with mycorrhizal inoculants such as DYNOMYCO®. DYNOMYCO® is Clean Green Certified and is approved for use in regenerative and sustainable agricultural practices.
DYNOMYCO® is Clean Green Certified and can be used in regenerative and sustainable or natural farming practices. In the US, cannabis is not federally legal, and since the word “organic” is regulated by the USDA, no cannabis farm can use the term “organic”. That being said, Clean Green uses similar standards as the USDA’s National Organic Program.
Initially, we suggest you add DYNOMYCO® into your growing media and stick to your growing protocol. After you’ve gotten comfortable and are seeing the benefits of using DYNOMYCO® you can begin to change your feeding rates. We’ve seen yield increases with growers who have reduced their P inputs as well as growers who have kept it just the same.
Yes. Since DYNOMYCO® boasts such high concentrations of mycorrhizal fungi you won’t need to purchase an inoculant which combines fungi and bacteria. You’ll be able to invest your money in an inoculant with bacteria only and still see incredible results.
Yes. See question “Do fertilizer or compost affect applications affect DYNOMYCO®” for a further explanation.
