About Growcentia

Our Story

Growcentia was founded by a team of three Colorado State University soil microbiologists with PhD degrees that share a passion for enhancing soil health and promoting sustainable agriculture. Using innovative proprietary technology, this team developed an approach to identify and apply nature’s very best microbes to improve nutrient availability to plants. Growcentia aims to help growers and farmers maximize the health of their soils or growth media to enhance plant health, quality, and yields while minimizing environmental impacts of agriculture.

Our technology has been extensively tested by growers and farmers around the world and by leading US academic institutions and is proven by these institutions and independent labs to increase growth. We are a Colorado company based in Fort Collins and all production is done in-house for quality control. Our beneficial bacterial formulas run clean in hydroponic systems and are an excellent way to derive organic benefits (OMRI listed in the US and Canada as well as California OIM certified) without sacrificing water quality.

Our products were developed by screening billions of soil microorganisms to identify those that most efficiently release bound phosphorus, making it available to plants. We then selected for further enhanced microbial efficiency, ultimately resulting in a consortium of soil bacteria that are thirty times more effective at releasing bound soil P.

Why We Are Different

Nutrient Cycling

Our development platform focuses on nutrient cycling processes that release soil P and micronutrients from bound forms, thus improving nutrient availability to plants.

High Throughput

Our high-throughput platform allows us to select highly-functional microbial consortia from the overwhelming microbial diversity found in natural soils – under conditions that ensure they work equally well in soil, soilless, and recirculating hydroponic systems.

Microbial Phenotyping

Our directed microbial phenotyping platform coupled with cutting-edge high-throughput molecular techniques is highly effective. Many other microbial products use a non-directed approach by simply mixing microbes, which results in a microbial concoction of unknown provenance or functionality.

Quality First

Quality control is a priority at Growcentia. Every production lot is quality-tested to ensure it meets our high standards using cutting-edge DNA sequencing analyses. Before releasing a product, we extensively test all our products in the lab, greenhouse, and field to ensure efficacy. New products will only be released if they meet our stringent standards.
