Growth Technology Clonex Rooting Gel: Professional Propagation SolutionAchieve near-perfect cloning success rates with the legendary Growth Technology Clonex Rooting Gel. Trusted by commercial horticulturalists and passionate hobbyists globally since its release in 1988, Clonex is a high-performance, water-based rooting gel that stays in firm contact with the stem, completely replacing traditional hormone powders and liquids.When you take a cutting, the open plant tissue is highly vulnerable to infection and air embolisms (bubbles that block moisture transport). Clonex instantly seals the delicate cut area to protect it. Concurrently, it delivers a potent dose of rooting hormones, vitamins, and minerals directly into the stem to trigger explosive, bright-white root development.
Key Features
- Advanced Gel-Based Grip: Adheres firmly to stem tissue, completely eliminating the risk of the hormone washing off during watering.
- Instant Embolism Protection: Seals the open cut immediately to block air bubbles from entering the stem and wilting the cutting.
- Hormone Booster Core: Infused with thousands of parts per million (ppm) of premium rooting hormones to accelerate initial root cell division.
- Built-In Nutrition & Vitamin Care: Contains a full profile of trace elements and minerals to feed young, emerging roots before they hit the soil.
- Anti-Microbial Action: Tough, protective barrier reduces the risk of fungal contamination or damping-off in humid propagation environments.
- Universal Media Compatibility: Performs exceptionally well in all propagation mediums, including Rockwool cubes, root plugs, coco coir, sand, and soil.

Step-by-Step Propagation GuideHygiene Tip: Never dip your cuttings directly into the original Clonex bottle. Pour a small amount into a separate shot glass or tray to keep your main container completely free from bacterial contamination.1. Select and Take the Cutting
- Choose a healthy, disease-free donor plant showing active vegetative growth.
- Make a clean, diagonal slice through the stem just below a leaf node using a sterile scalpel or sharp trimming shears.
2. Dip in Clonex Gel
- Immediately dip the bottom 10mm to 20mm of the freshly cut stem directly into your decanted Clonex gel.
- Ensure the entire cut area and the exposed node are completely coated in a smooth, thin layer of gel.
3. Insert and Secure
- Place the treated cutting straight into your pre-moistened propagation plug, rockwool cube, or potting mix.
- Press the medium gently around the stem to lock out light and ensure close structural contact with the gel.
4. Humidity and Rooting
- Move your cuttings into a specialized propagation dome or a humid greenhouse environment.
- Maintain a high relative humidity level (around 80–90%) and stable warmth. Roots should begin to emerge clearly within 7 to 14 days depending on the plant species.
