Clonex Rooting Gel 50ml — Professional-Grade Rooting Hormone for Plant Cuttings
Best for: Growers taking cuttings who want a reliable, proven rooting gel that actually works without the faff
Our thoughts
Clonex has been the go-to rooting gel for serious propagators since 1988, and for good reason. It's not the cheapest option, but you're paying for a track record that includes over a billion successful cuttings. If you're serious about propagation, this is one we'd recommend without hesitation.
Clonex Rooting Gel is a water-based, hormone-rich gel formulation designed to seal fresh cutting wounds and trigger rapid root development. Supplied in a convenient 50ml bottle, it contains a full-strength 3000 parts per million of rooting hormone alongside anti-fungal agents, growth nutrients, and trace elements. Unlike older rooting powders, the gel stays in contact with the cutting throughout the rooting period, delivering consistent hormone support and protection against infection. It's the kind of product that turns propagation from a guessing game into something you can actually rely on.
How it compares
Rooting gels sit above powders in terms of convenience and results, though they cost more per application.
- Gel format stays put — doesn't wash off or blow away like powder
- Seals the cut instantly, eliminating risk of stem rot or air embolism
- Full-strength IBA formula delivers faster rooting than weaker alternatives
- More expensive per use than powder, but you're paying for reliability and ease
- Clonex specifically has 35+ years of proven track record in professional propagation
If you've tried rooting powder and found it hit-or-miss, or you just want to cut the guesswork out of propagation, gel is the smarter move. Clonex is the premium choice in that category.
Usage guidance
Using Clonex is straightforward, but technique matters:
Preparation
Take healthy cuttings from the parent plant, ideally 4-6 inches long with a clean, sharp cut. Strip the lower leaves off.
Application
Pour a small amount of Clonex into a separate container — never dip directly into the bottle, as this contaminates the stock. Dip the freshly cut end into the gel so it's fully coated, then insert straight into your rooting medium (perlite, rockwool, coco, or peat).
Environment
Mist the cuttings and place them in a warm, humid, clean space. Bottom heat (18–24°C) speeds things up. Keep conditions moist but not waterlogged.
Results
Root development typically shows within 1–2 weeks. Expect success rates of 95%+ when technique is decent. A single 50ml bottle will treat roughly 30–50 cuttings depending on size.
Key tip
Don't overdo the gel. A light coating is enough — excessive gel can trap moisture and cause rot if the cutting sits in it too long.

Who this is for
- Growers taking cuttings regularly and wanting consistent, high success rates

- Professional operations where reliability matters and failures cost money
- Anyone scaling from one or two cuttings to bulk propagation
- Growers who've tried powders and want something that actually stays on the cutting
Less suited to very occasional propagators (a single packet option might be better value), but absolutely essential if you're doing this regularly.
Our take
Clonex is expensive for a reason — it works. The gel stays put, the hormones are at full strength, and the anti-fungal protection actually prevents the rot that kills cuttings. You get faster rooting, better success rates, and one less thing to worry about.
If propagation is part of your regular growing routine, this is worth picking up. Does exactly what a rooting gel should do, day in, day out.
