MitoGrow: The American-Made Plant Nutrient Supplement by Mitigrow

Part of the America250: Built Here. Built Better. series — celebrating the American makers, manufacturers, and entrepreneurs behind every FLI Products innovation.

Every serious gardener knows that soil and water alone aren't enough. Plants need the right nutrients — delivered at the right time, in the right form — to reach their full potential. And most of the nutrient supplements on the market are either too complicated, too expensive, or formulated for commercial agriculture rather than the home gardener who just wants bigger tomatoes and healthier plants.

MitoGrow was designed for that gardener. And it was designed and manufactured right here in the United States.

MitoGrow is an American-made plant nutrient supplement formulated to boost root development, strengthen plant health, and improve yields for tomatoes, vegetables, herbs, and garden plants. It's the nutrient solution that completes the FLI Products garden ecosystem — working alongside the Tomato Crater to deliver nutrients directly to the root zone where plants need them most.

Built by Mitigrow — American Innovation for American Gardens

MitoGrow is manufactured by Mitigrow, an American company and FLI Products partner dedicated to developing plant nutrition solutions that work for real home gardeners. Mitigrow brings formulation expertise and a commitment to domestic manufacturing to a product category dominated by complex commercial programs and cheap import alternatives.

The Complete Garden Ecosystem

MitoGrow is designed to work as part of Tom Whitaker's complete garden system — the most effective combination of American-made tools and nutrients for serious home gardeners:

Tomato Crater — delivers water and nutrients directly to the root zone
Stake It — anchors trellises and supports without digging
C-Bites — modular plant support clips for tomatoes, peppers, and climbing plants
Stratus Rain Gauge — tracks rainfall so you know exactly how much water your garden is getting
MitoGrow — the nutrient supplement that feeds plants at the root zone for maximum uptake and yield

Together, these American-made products give home gardeners a complete, science-backed system for growing stronger plants and bigger harvests.

"Most gardeners are leaving yield on the table because they're not feeding their plants at the root zone. MitoGrow paired with the Tomato Crater is the most effective combination I've used — the nutrients go exactly where the plant can use them, and the results show up in the harvest. All American-made. All built to work together." — Tom Whitaker, FLI Products Advisor

Why Root Zone Nutrition Matters

Surface fertilization is inefficient — a significant portion of surface-applied nutrients never reaches the root zone, lost to runoff, evaporation, and soil binding. Root zone nutrition delivers nutrients directly where plants absorb them. When paired with the Tomato Crater, MitoGrow achieves maximum nutrient uptake with minimum waste:

Stronger root development — nutrients at the root zone encourage deeper, more extensive root systems
Improved plant health — well-nourished roots support stronger stems, more foliage, and better disease resistance
Higher yields — tomatoes, peppers, cucumbers, and vegetables produce more fruit when nutrient uptake is optimized
Less waste — targeted delivery means more of every application reaches the plant
