This is a very interesting article examines cannabis microbiota studies and the effects of endophytes on the elicitation of secondary metabolite production in cannabis plants. The review aims to shed light on the importance of the cannabis microbiome and how cannabinoid compound concentrations can be stimulated through symbiotic and/or mutualistic relationships with endophytes.
Dynamic accumulators (DA) are plants that gather certain minerals and nutrients from the soil and store them in higher concentration in their leaf tissues. The leaves of the plants can then be used as compost, mulch or liquid fertilizer. The truth is that most plants, in a way, are dynamic accumulators in some way because they translocate the soil minerals into their leaves. The difference however, is that certain plants, like horsetail, nettle or buckwheat, for example, tend to pull specific nutrients up in greater amounts. Horsetail is well known for silica, nettle is well known for iron and buckwheat is known for accumulating phosphorus. Other DA”s like comfrey or yarrow are more all purpose accumulators and pull out more proportional balanced NPK ratios. DA’s are traditionally thought of as a class of plants associated with nutritive and medicinal herbs. But please don’t confuse DA’s as a specific class of plants, for they can also include other types of flowers and cover crops as well.

Plant growth-promoting (PGP) microbes are rhizosphere associated organisms that colonize the rhizosphere and rhizoplane and improve plant growth when artificially inoculated onto the seeds or into soil. PGP microbes may promote plant growth either by direct stimulation such as iron chelation, phosphate solubilization, nitrogen fixation and phytohormone production or by indirect stimulation such as suppression of plant pathogens and induction of resistance in host plants against pathogens. The opportunities of PGP microbes include alternating applications of PGP microbes as bio-fungicides with inorganic fungicides to manage fungicide resistance and to reduce the number of fungicide applications per year. PGP microbes also plays an important role in inte-run-off of unused fertilizers and the environment damage that results.
OG BioWar is a product that has been used rather extensively by a group of conscious minded farmers here in Humboldt County. The root pack is a microbial inoculant. It is a blend of highly concentrated beneficial fungi and bacteria that perform many important functions in the rhizosphere. The root pack promotes plant health by boosting the immune system, increasing shoot and root growth, multiplying flower production and increasing essential oil production. The entire line of OG BIOWAR is worth checking out, definitely a CHA recommended product for biological controls.
Effective Microorganisms® Amendments For Agriculture
Effective Microorganisms® has been used in agricultural applications since 1982. Farmers have documented vast benefits of EM·1® on 6 continents, demonstrating that EM·1® Microbial Inoculant works in all soil types, all farming systems and all climates on Earth. Today, EM·1® organic soil amendments are used in over 120 countries in all sorts of farming systems from row crops to orchards to composting to aquaculture to solid and liquid waste management. Whether conventional, organic or sustainable, any farming method can benefit from using EM•1® to improve the efficiency of their operation. EM·1® Microbial Inoculant is approved for use without restrictions on Certified Organic operations (OMRI Listed).
Those crazy scientists have done it again, throwing generally accepted theories of life science out the window. A group of Australian researchers have shown that plants are able to consume whole bacteria and yeast cells. Prior to this, our understanding of the root/microbe relationship revolved around the idea that microbes provided nutrition to plants. Bacteria can make nitrogen available, as well as solubilize phosphorus, potassium and micronutrients into forms that are plant friendly. Fungi perform a similar role, directly transporting nutrients and water into plants via the mycorrhizal networks. These mechanisms are pretty well understood and accepted as common. What’s not so commonly known is that plants can eat whole microbes. Yes, plant roots are able to devour bacteria and yeasts. The term proposed for this newly discovered mode of nutrition is Rhizophagy (rhye-zo-fay-jee).
