Welcome!
At Mighty Plant, we believe the future of gardening starts below the surface. Healthy soil creates healthier plants, richer harvests, and more resilient gardens — which is why every product we create is designed to support the biology, nutrient flow, and natural systems plants depend on to thrive. Our formulations combine advanced plant science with organic growing principles to help growers achieve exceptional results without compromising the health of their soil.
From vibrant vegetable gardens and thriving houseplants to large-scale horticultural operations, Mighty Plant products are trusted for their purity, performance, and ease of use. We are passionate about creating innovative biologicals and organic plant foods that help growers cultivate stronger roots, healthier foliage, increased blooms, and more productive harvests — naturally.
Meet Our Founder
David Keen founded Mighty Plant after more than 50 years spent developing innovative products for the horticulture and agricultural industry. From studying Agronomy, Plant Physiology, and Biochemistry at the University of Florida to helping introduce groundbreaking technologies used by growers around the world, David’s career has always centered around one thing: helping plants perform at their highest potential.
After building and selling a successful agricultural company, David’s love for horticulture and gardening ultimately brought him out of retirement to launch Mighty Plant with a new mission — creating advanced organic plant nutrition designed to work at the cellular level. One of the first innovations developed through Mighty Plant was Instant Compost Tea™, a fast, water-soluble bio-stimulant that reimagined traditional compost tea for modern growers. Today, his formulations combine decades of scientific experience with a passion for healthier plants, stronger harvests, and more sustainable growing practices.

The Road to Mighty Plant
A Defining Chapter
Right out of high school, David Keen spent a year in Vietnam — an experience that completely changed the direction of his life. The challenges he faced there taught him resilience, discipline, and the ability to adapt under pressure.
Those lessons stayed with him long after returning home and became the foundation for the determination, persistence, and work ethic that would later shape Mighty Plant.
Decades of Innovation
David Keen began his career with Geigy Chemical, a pioneering Swiss company that would later become part of Syngenta, now one of the largest agricultural companies in the world. Over the decades that followed, he helped introduce and develop products and technologies that growers around the world still rely on today.
- Humic & Fulvic Acids
- Mycorrhiza
- Organic Insecticides
- Phosphite Fungicides
- EDTA Chelating Agents
- Water Absorbent Polymers
- Acetate Based Nutrients
Today, that same passion for innovation continues through Mighty Plant and its next generation of biological and organic growing solutions.
The Move Toward Organic Growing
After decades in conventional agriculture, David Keen saw firsthand both the strengths and the limitations of traditional chemical growing. Over time, he became increasingly interested in creating products that could deliver exceptional performance while working more naturally with the biology of plants and soil.
That vision led to the founding of Organic Laboratories, where David began developing natural solutions designed to perform at the same level as conventional products. What started with mixing organic insecticides in a five-gallon bucket eventually grew into a nationally distributed company with large-scale manufacturing and automated production facilities.
Today, that same philosophy continues through Mighty Plant — developing advanced biologicals and organic plant nutrition that combine strong performance with a more natural, soil-focused approach to growing.

Customer Testimonials
"Less than one day after applying Mighty Plant Instant Compost Tea, my plants stood up and perked in a celebratory response. I absolutely love this stuff but plants love it even more."
- John, Amazon Customer
"I watched the garden absolutely light up over the next couple of days after using this product, If you are not gardening with a view to “live soil” then this stuff will get you started with a blast of microbial life. It dissolves instantly, no mess, does not smell unpleasant. Go for it! You’ll love how your garden grows."
- Mashu, Amazon Customer

100% ORGANIC
Organo Grow was created to challenge the idea that organic growing has to mean weak performance. Featuring a powerful 8-2-6 NPK plus 3% calcium, it uses blood meal converted into blood plasma and broken down into individual amino acids, delivering nutrients in a form plants can absorb and direct immediately where they’re needed most — resulting in an unusually fast organic response.
New Products On The Horizon
Quell™ Biostimulant
We’re going deeper than nutrients alone — all the way to the cellular level. QUELL™ Biostimulant was created to help plants combat oxidative stress caused by free radicals, unstable molecules that can damage DNA, mitochondria, and overall plant performance.
Powered by Glutathione, one of the most powerful antioxidants known to science, QUELL™ helps neutralize free radicals and support healthier cellular function — helping plants operate closer to their true genetic potential with stronger growth, improved vitality, and more consistent performance.
Green ReLeaf™ Fungicide
Powdery mildew is often harder to control because most sprays leave gaps in coverage as water beads up across the leaf surface. Those unprotected spaces become the perfect environment for mildew to establish and spread.
Green ReLeaf™ combines potassium bicarbonate with a high-performance surfactant that helps the spray spread evenly across the entire leaf surface instead of beading up — delivering more complete coverage with fewer places for mildew to hide.
