What is Growth Technology Clonex Purple Rooting Gel used for?
Clonex Purple is a medium-strength rooting gel designed to encourage fast, reliable root growth in semi-hardwood cuttings. It contains the synthetic rooting hormone IBA, plus ingredients that protect the cutting and support early development. The purple colour indicates its strength in the Clonex range.
Which cuttings work best with Clonex Purple?
Clonex Purple is ideal for semi-hardwood cuttings—firm but not fully woody stems. It can be used on softwood or hardwood cuttings, but softer cuttings may prefer gentler formulas. It's also popular for propagating houseplants, shrubs, and ornamentals like rosemary or lavender.
How do I apply Clonex Purple Rooting Gel correctly?
Decant a small amount into a clean container, dip the cut end of the stem just deep enough to coat the rooting zone, and plant immediately into your media. Avoid double-dipping or using too much gel—a thin, even coat is all you need.
Can I reuse leftover Clonex Gel after decanting?
No—discard any leftover gel after dipping. Once exposed to plant material or air, the gel can become contaminated and reduce your success rate.
What propagation media can I use with Clonex Purple?
Clonex Purple works well with rockwool, coco, peat, soil mixes, and even aeroponic cloners. It’s not ideal for water-only propagation. Keep your media moist, airy, and clean—overwatering is a top reason cuttings fail.
Do I need a humidity dome when using Clonex Purple?
In most cases, yes—cuttings root best in high humidity. Use a dome early on and vent regularly to prevent mold. Keep temps warm and stable, and avoid blasting cuttings with intense light before roots form.
Why aren’t my cuttings rooting with Clonex Purple?
If you see callus but no roots, conditions may be too cold, wet, or the hormone may be too strong for the plant type. Improve airflow, reduce moisture, and check that tools and gel aren’t contaminated.
Can Clonex Purple damage cuttings?
It’s rare, but sensitive plants or improper technique can cause stress. If stems go slimy or roots stall, consider switching to a lower strength gel and review your environment (airflow, humidity, media).
Should I wound the stem before applying Clonex?
It's optional. On woody or tough stems, lightly scraping can help. But for softer cuttings, it's not necessary and may increase infection risk. Always use clean tools and minimal wounding.
How should I store Clonex Purple Rooting Gel?
Store it cool, dark, and sealed—many growers refrigerate it. Avoid heat and sunlight, which can break down the gel or cause it to separate. Don’t leave it open during long sessions to avoid contamination.
Does Clonex Purple expire or go bad?
Yes—check the packaging for expiry dates. Opened gel can last if stored properly, but if it becomes watery, smells off, or was double-dipped, it’s safer to replace it.
Is Clonex Purple safe to touch? Do I need gloves?
It can irritate skin or stain, so gloves are recommended. Avoid contact with eyes and wash hands after use. For spills or exposure, follow the product's safety instructions or SDS guidelines.
Is Clonex Purple suitable for beginners?
Yes—it's straightforward and effective. Most mistakes come from contamination (double-dipping), poor airflow, or overwatering. Stick to clean tools, proper technique, and stable conditions for the best results.
How many cuttings can one bottle of Clonex Purple treat?
You’ll get a surprising number—hundreds, depending on how deeply you dip and how thick the stems are. Use minimal gel and always decant to stretch each bottle further.
How does Clonex Purple compare to rooting powders?
Gels like Clonex coat evenly, stick better to cuttings, and seal the wound site, reducing dehydration and infection. Powders can fall off or apply unevenly, especially on soft or sappy stems.
