Explore our most advanced nutrient and supplement lineup below.
Silver Bullet
Bioavailable Sulfur for Optimal Growth and Aroma
Silver Bullet delivers elemental sulfur in a completely soluble form, ensuring immediate availability to plants. Sulfur is essential for enzymatic activity, chlorophyll production, and terpene synthesis — making this one of the most powerful and clean sources available for high-value crops.
Growers trust Silver Bullet for its unmatched consistency and compatibility across organic and hydroponic feeding programs. It mixes cleanly, leaves no residue, and supports a balanced nutrient profile from veg through flower.
“I put this stuff on my plants and have never seen them grow like that.”
— Tina Wong, Backyard Farmer
Endzyme Pods
Natural Enzymatic Catalysts for Nutrient Cycling
Endzyme Pods accelerate the breakdown of organic matter and dead root material, freeing up locked nutrients for reuse by the plant. This process supports root health, enhances nutrient absorption, and helps prevent buildup in both soil and hydro systems.
Each pod contains a carefully stabilized enzyme complex that’s easy to measure, clean to mix, and highly effective even at low concentrations. It’s an essential addition for growers focused on root-zone efficiency and long-term system balance.
Green9
Balanced Micronutrients for Canopy Uniformity
Green9 is Key To Life’s flagship micronutrient blend, engineered for total solubility and precise uptake. It provides all nine essential trace elements plants require — including iron, manganese, zinc, copper, boron, molybdenum, cobalt, nickel, and chlorine — in a balanced ratio that supports vigorous growth and uniform development across the canopy.
Because each element is chelated and solubilized for compatibility, Green9 integrates seamlessly into any feeding schedule and works beautifully alongside the full Key To Life nutrient suite.
Cal(No)Mag
Pure Calcium Supplement Without Unwanted Additives
Cal(No)Mag delivers highly bioavailable calcium with zero nitrate or magnesium content, offering complete control over your nutrient ratios. This makes it the preferred solution for growers who want to fine-tune calcium delivery without altering EC or compromising sulfur balance.
By strengthening cell walls and improving nutrient transport, Cal(No)Mag supports more resilient plants with better structure, fruit density, and shelf stability.
Key To Uptake
Enhanced Nutrient Absorption Through Chelation and Transport
Key To Uptake improves nutrient solubility and mobility, ensuring that every part of your feed schedule performs at maximum efficiency. This formula is designed to support the chelation process naturally, increasing availability of micronutrients and supporting balanced root-to-shoot transport.
When combined with compost teas or biological inputs, Key To Uptake enhances the plant’s natural uptake capacity, reducing waste and boosting visible growth response.
“This stuff in combination with my compost tea is an absolute dream. Blooms like never before.” — Stephanie Rogers, Horticulturist
Key To Boost
Amino and Mineral Complex for Rapid Growth
Key To Boost provides the essential amino acids and minerals that power vegetative expansion and root development. It’s formulated for immediate solubility, ensuring clean mixes and fast plant response.
Regular use during early veg or transition stages strengthens structure, improves chlorophyll density, and sets up the foundation for higher yields later in the cycle.
Used in combination with Key To Uptake or Revitalize, it delivers consistent, healthy growth in all media types.
Key To Kelp
Cold-Processed Kelp for Growth and Stress Resistance
Key To Kelp is made from sustainably harvested, cold-processed kelp meal to preserve natural plant hormones like cytokinins and auxins. This supplement supports cell division, root initiation, and resistance to stress.
Growers use Key To Kelp as a foliar spray or soil drench to improve vigor, increase nutrient uptake, and promote faster recovery after environmental shifts. It’s one of the simplest, most effective natural tools for boosting plant performance across all growth stages.
Root Life Microbes
Living Soil Biology for Regenerative Cultivation
Root Life Microbes is a premium biological inoculant that delivers a diverse population of beneficial bacteria and fungi. These organisms work symbiotically with plant roots to improve nutrient conversion, water retention, and disease resistance.
Compatible with organic, coco, and hydro systems, Root Life Microbes builds resilient root zones and strengthens plants from the ground up. It’s the foundation of long-term soil vitality and productivity.
Key To Silica
Strengthen Plant Structure and Stress Tolerance
Key To Silica delivers a soluble form of silicon that reinforces plant cell walls, improving overall structure, drought tolerance, and pathogen resistance. Stronger stems and thicker leaves also translate to better support for heavy fruit and flower development.
This formula dissolves instantly and mixes cleanly, making it a reliable supplement throughout the entire growth cycle.
Revitalize
Rebuild Soil Life, Restore Balance, and Recharge Growth
Revitalize is a cornerstone of the Key To Life system — a complete biological amendment designed to re-energize soil ecosystems and improve microbial population diversity. Ideal for use during the vegetative stage, it replenishes organic matter, supports beneficial microbial activity, and helps maintain balanced nutrient cycling.
“Revitalize has been a game changer for my grow. Use this in your vegetative stage and you’ll be glad you did.” — Angela Nguyen, Backyard Farmer
Molasses Magic
Carbon Energy Source for Soil Microbes
Molasses Magic provides the simple carbohydrates that fuel microbial activity, encouraging healthy populations of beneficial bacteria and fungi. As a result, plants experience improved nutrient exchange, stronger root health, and better overall soil fertility.
It’s a natural, renewable supplement that supports sustainable soil management and fits perfectly into regenerative cultivation systems.
Root Life Fungi
Mycorrhizal Support for Maximum Root Expansion
Root Life Fungi introduces beneficial mycorrhizal strains that colonize plant roots and dramatically expand their effective absorption area. This symbiotic relationship allows plants to access water and nutrients far beyond their normal reach, promoting improved growth, higher yield potential, and long-term soil health.
Easy to apply and fully compatible with all nutrient programs, Root Life Fungi is the biological bridge between clean chemistry and natural biology.
