Changing the Game......

While the idea of microbial inoculants for stimulating crop production is not new, careful and deliberate design of a formulation to contain multiple, naturally occurring phylogenetic groups of organisms with complementary functionalities and noticeable effects from seed to final flush, with little or no need for added chemical fertilizers and pesticides is innovative.

URB Sciences believes the design of the URB product line is better than any of its competitors since it takes a holistic, synergistic approach to boosting crop yields and decreasing inputs in a sustainable manner. The documented benefits achieved with URB are clearly better than any known competitor.

All liquid formulations are Certified Organic by OMRI, ENVIROCANN & CLEAN GREEN


Our precision engineered microbial formulation is suspended in a triple screened 12% humic acid carrier, stabilized at a balanced pH of 7.0, which allows it to effectively work in all mediums and growing systems.These humates act as a carbon food source for the microbial formulation, are high in organic matter and contain micronutrients, such as calcium, magnesium, zinc and manganese.


URB is akin to feeding a human organically grown food and nutritional supplements in a nurturing environment rather than junk food and steroids in a neglectful environment. Conventional growing utilizes petrochemical based fertilizers, boosters, and PGRs. This is the equivalent of using steroids; they will produce gains in the short/medium term while causing environmental degradation during the process and almost always result in some smoke that loses its flavor 1/4 of the way into your joint. ⁣
Eco-friendly would typically mean not harmful to the environment. URB products go beyond eco-friendly.⁣
In addition to NOT using harmful chemicals, URB rehabilitates the soil, making the soil healthier. Our products will enhance the soil’s ability to naturally remediate existing soil contaminants, improve its water retention capacity, improve its chelating abilities to prevent the leeching and runoff of pesticides and other chemical applications, and improve the soil’s organic mass for sustainable production of plant⁣life.⁣


With 6 strains of microbes (of different genus and species) 𝐬𝐮𝐬𝐩𝐞𝐧𝐝𝐞𝐝 𝐰𝐢𝐭𝐡𝐢𝐧 𝐚 12% humalite derived liquid humate solution ( which provides huge benefits on its own) .. URB amends the soil helping nature fend for itself. Even in inert mediums.... It stimulates germination rates, nutrient uptake, bacterial resistance, root penetration and transpiration to increase crop yields and potency without ANY non-organic materials. Our goal with growers is succeeding because they are now reducing chemical inputs by building the life around the root zone instead of feeding the plants. Chemical fertilizers lead to more damage, less resistance, and ecological damage.⁣
3x Certified Organic, If you have tried the rest, its time to try the best.


URB Natural is made from cultivated, not genetically modified strains of microbes. It contains six strains of microbes of different genus and species. It is certified organic by 3 different organizations. The concentrations of each strain of microbes are delicately arranged so that they work cohesively within the root zone, rather than compete. It is a feat that is not easily achieved and when you use our product you will realize what a successfully arranged consortium of microbes looks like. URB Natural was designed to retain viability over time and its microbes work cohesively within the applied medium. ⁣
You can think of URB as a multi-vitamin. (poly-microbial within a liquid humate suspension) Think of our competitors’ products as Vitamin C (one genus slapped together) Actually, our product would be more correctly referred to as a perfect food since it contains vitamins & minerals and also has the ability to produce or mobilize them. It also adjusts its own environment by correcting the pH and allowing greater efficiency in water utilization.⁣ The URB formulation includes liquid humates (derived from Humalite) and plant micro nutrients. Humates are the backbone of healthy soil. They promote the growth of beneficial microbes and give the soil the proper compaction, cation exchange capacity (CEC), and the ability to retain water and nutrients while making them readily available to plants. Humate derivatives are mixtures of humic, ulmic and fulvic acids. They are products of organic matter transformation by the soil microorganisms. Organic matter (OM) is the source of energy and food supply for microbes giving them an extra kick when they hit the grow medium an ensuring viability during storage and transit. Humic acid derivatives have several known benefits to Cannabis on their own. These benefits include increasing seed germination, improving trace element nutrition through chelation, and improving moisture conditions. Be warned, all humates aren't the same. We encourage you to do a google search on the difference between "leonardite and humalite" derived humates.
