Frequently Asked Questions

What is Clonex Rooting Hormone Gel (Clonex) used for?

Clonex Rooting Hormone Gel is the world’s first and leading propagating gel. It's a gel-based hormone formulation designed to promote the formation of roots in plant cuttings, which is crucial for successful cloning and propagation. The key benefits of using Clonex include quicker and healthier root growth, and healthy plant establishment. Unlike powder rooting hormones, Clonex’s gel consistency makes it easy to apply directly to the cut surface without worrying about excess powder or mess. It also helps the hormone stay in place, ensuring that the cutting receives consistent exposure to the rooting agents.

How do I choose the right strength of Clonex?

Each Clonex product is colour-coded for convenience:- Green (1.5g/L IBA) – Ideal for softwood cuttings- Purple (3.0g/L IBA) – Best for medium wood cuttings- Red (8.0g/L IBA) – Perfect for hardwood cuttings. If there is callusing but no root formation this indicates the hormone level is too high, and a lower hormone concentration should be used.

How do I use Clonex Rooting Hormone Gel?

To use Clonex, clean and sterilise your tools before starting. Cut your stem at a 45-degree angle just below a node, dip it into the Clonex Gel, and place the cutting in your chosen growing medium. Follow best propagation practices for the best results.

Why does Clonex gel liquefy?

Exposure to extreme temperatures or improper storage can cause Clonex gel to liquefy. For best results, store the gel in a cool, dark place (preferably in the refrigerator) and avoid contamination by not dipping cuttings directly into the bottle.

Is Clonex safe to use?

Yes, Clonex is safe for use on all types of plants, including medicinal plants, and is APVMA-registered for your peace of mind.

What is the usage capacity of a bottle of Clonex?

This depends on the diameter of the cutting and the depth to which the cutting is dipped, but the grower should expect several thousand cuttings per litre of Clonex.

How long does Clonex remain effective after opening?

Clonex Gel is guaranteed to be effective for up to two years if the recommended guidelines are followed.

These guidelines include not dipping directly into the Clonex bottle; instead, always decant the required amount and dispose of any excess. Store the Clonex in the refrigerator where possible, or in a cool, dark place. Clonex gel liquefies when exposed to warm conditions. Its viscosity will return once it is placed back into cooler conditions.

What is the difference between Clonex Clone Solution (CCS) and Rootzone?

CCS and Rootzone each play a unique role in plant growth. CCS is a specially formulated nutrient solution that provides cuttings and seedlings with essential nutrients for strong root development and healthy early growth, giving young plants the best start possible. Rootzone, an organic-based supplement, supports plants throughout their entire life cycle by enhancing nutrient uptake and promoting optimal root health. It ensures plants continue to thrive as they mature. Together, CCS and Rootzone form a seamless nutrient system – CCS gives seedlings a strong foundation, while Rootzone offers long-term support – ensuring your plants grow healthy and productive from first sprout to final harvest. Whether you're new to hydroponics or a seasoned grower, these two products working together ensure your hydroponic garden flourishes at every stage.

"Since its inception over 35 years ago, Clonex gel has led to my success in growing many difficult, previously ungrown species of WA wildflowers, new to horticulture. This includes both the introduction to Perth gardens, and for revegetation. The ability of Clonex to produce roots along the treated stems ensures solid growth of the cuttings. I use the Clonex Purple gel for the majority of species, with ongoing success"
