Radix Laboratory Grade Rooting Hormone Stimulator for Seeds, Cuttings, Propagation, and Veg
Radix is a laboratory-grade rooting hormone stimulator designed to accelerate root development for seeds, cuttings, and plants in vegetative growth. It has been used for years in large-scale medicinal and hemp production facilities in Canada and is now available to growers in the United States who want faster, denser root systems in hydroponic and traditional media.
Radix Directions for Use
For hydroponic methods and reservoirs with continuous oxygenation: add 1 ml per gallon.
For all media including soil, coco coir, rockwool, and reservoirs without continuous oxygenation: add 1.5 ml per gallon.
Add Radix every feeding from seed through the first four weeks of your flowering phase.
What Is Radix Rooting Hormone?
Radix rooting hormone is a dedicated root stimulator originally formulated for high-end medicinal operators in Canada. These facilities often span hundreds of thousands of square feet and require custom nutrient blends tailored to hemp and medicinal crops. Radix was built to meet those standards and is now bottled and distributed for everyday growers.
You can think of Radix as a blend of several proven rooting stimulators on the market, combined into one formula and supported with humic and fulvic acids. These organic acids do not add large amounts of N-P-K on their own, but they improve nutrient uptake and root efficiency. The primary design of Radix is simple: drive fast, healthy root growth in plants of all ages and sizes, from fresh cuttings to well-established veg plants.
Radix was originally built for large-scale medicinal facilities, but the same formulation is now available to small- and large-scale hydroponic growers who want consistent rooting performance without a complicated feeding program.
Why Radix Is a Strong Alternative to More Expensive Rooting Hormones
Before bringing Radix to market, it was trialed in-house with the team and with about ten commercial grow facilities. These are real-world operations that were already using well-known root stimulants and were willing to compare Radix side by side.
There are some excellent rooting stimulators out there—products like Roots Excelurator, for example, which Nate holds in very high regard. The challenge is that these top-tier products can start to put serious pressure on your budget, especially in larger facilities.
Radix was positioned as a cost-effective alternative. When you compare MSRP to some of the most popular premium root stimulators, Radix often comes in at roughly 60% less. That price difference adds up quickly when you are treating thousands of clones or feeding multiple large reservoirs. The goal with Radix is to keep rooting success high while lowering your cost per plant.
How Growers Are Using Radix in Propagation
Most growers who tested Radix started with fresh clones. They soaked their propagation media—such as Root Riot-type propagation plugs, other propagation cubes, or Grodan rockwool—in a light Radix solution and then rooted cuttings as usual.
For this propagation phase, a common application rate is about 0.5 ml per gallon. This is a very small amount, but it is enough to support early root initiation and development in tender cuttings. Once plants are rooted and moved into veg, growers typically increase to 1–1.5 ml per gallon, depending on their setup and media.
You can continue running Radix through veg and into early flower—up to around the first four weeks—when root expansion and foundation-building are still critical.
Compatible Media and Systems for Radix
One of the practical benefits of Radix rooting hormone is how flexible it is across different systems and grow styles. Growers have successfully used it in:
-
Drip drip irrigation systems feeding coco and soil mixes
-
Deep Water Culture (DWC) and other recirculating reservoirs
-
Standalone buckets, slabs, and rockwool blocks
Radix can be used in both continuously oxygenated hydroponic systems (like DWC) and in setups where the reservoir is not constantly aerated. The only change is the dose: 1 ml per gallon for oxygenated systems, and 1.5 ml per gallon for media and non-aerated reservoirs.
When you first open Radix, you will notice it is not the sweetest-smelling product on the shelf. That said, the focus is on performance and plant response, and in trials it has consistently proven effective at supporting vigorous root development.
Clean, Transparent Rooting Hormone for Medicinal-Grade Production
Radix was designed for medicinal crops, which means it must be very clean and consistent. States like Massachusetts, Washington, and Oregon hold nutrients and additives to extremely high testing standards. Radix was formulated so it can pass those tests, making it suitable for commercial facilities that cannot risk contamination or unlisted residues in their root stimulator.
Most nutrient lines are a bit of a black box when it comes to what is actually in the bottle. One of the standout features of Radix is its transparency. The primary ingredients are listed clearly on the product documentation so growers know exactly what they are feeding their plants.
On the Radix product documentation, commercial growers can also access the Material Safety Data Sheet (MSDS). This is especially useful for operations that must maintain strict compliance records, but it is also helpful for curious hobbyists who want to understand their inputs.
Results from Commercial and In-House Trials
During early evaluations, Radix was used by staff growers and multiple commercial facilities already working with other premium rooting products. Across these tests, Radix showed that it could:
-
Support strong rooting in fresh cuttings placed into propagation plugs, rockwool, or similar media
-
Integrate smoothly into existing feeding programs in hydroponics, coco, and soil without forcing major changes
-
Offer rooting performance comparable to more expensive root stimulators while significantly lowering cost per gallon
Radix has also been featured in real grow operations, including its appearance in Canna Cribs Episode 5 at Honeydew Farms, where it was used in propagation. This kind of real-world visibility is helpful for growers who like to see products working in production environments—not just on a spec sheet.
Key Takeaways for Hydroponic Growers
For hydroponic and soilless growers looking for a reliable, cost-conscious rooting hormone stimulator, Radix offers a few clear advantages:
-
Purpose-built for roots: Radix focuses specifically on root development, pairing rooting stimulators with humic and fulvic acids to improve nutrient uptake and root performance.
-
Hydroponic-ready dosing: Simple rates (1–1.5 ml per gallon) make it easy to integrate into existing feeding schedules for hydroponic systems, coco coir, and soil.
-
Commercial-grade cleanliness: Formulated to meet strict state testing standards, making it suitable for medicinal and large-scale operations.
-
Transparent formulation: Primary ingredients are disclosed, giving growers more confidence in what they are applying to their crop.
-
Budget-friendly: Compared to many premium root stimulators, Radix typically comes in around 60% less in MSRP, reducing rooting costs across large plant counts.
Casual Wrap-Up from Nate
So, that is Radix in a nutshell—a clean, transparent rooting hormone stimulator that was built for serious commercial facilities but works just as well in a home grow or mid-size hydroponic setup.
If you are running hydro, coco, or soil, and you want to test a new root stimulator without blowing up your nutrient budget, Radix is worth a look. It is simple to dose, plays nicely with most base nutrients, and is built to pass strict testing standards.
I am also genuinely curious: what is your favorite rooting stimulator right now? If you have a product you swear by, drop it in the comments. Seeing what other growers are using and how they are applying it is one of the best ways we all learn and dial in our systems.
