The summary

What it is: a propagator that roots cuttings without soil or pots — the stem held in place by a split neoprene disc, with the base in contact with constantly refreshed water.
Two sizes, two principles: 27 sites on a 13 L grow bed oxygenated by an air pump, or 72 sites using aeroponics, watered by a rotating head above a 70 L grow bed.
No consumables: the neoprene discs can be washed and reused, batch after batch. No rockwool cubes to replace.
The timescale: 10 to 14 days on the 72-site model, 14 to 21 days on the 27-site model, with easy species and water around 20 degrees.
What you add: a rooting hormone for woody cuttings, gentle lighting, and heat if your room is cool.
Footprint: 67 x 29 x 15 cm and 2.86 kg for the 27-site model, 67 x 67 x 32 cm and 11.8 kg for the 72-site model.

Rooting without soil or consumables: 27 positions in oxygenated water, or 72 in aeroponics

A cutting must form roots before it dries out, and for that it needs constant water and oxygen around its base. The two cutting propagators offered here give you two answers to that need: the model 27 through the constant movement of the water, the model 72 through a rotating mist above an open space.

💨 The oxygenated tank, 27 cuttings

A 4 W air pump injects air into the 13 L tank through two lines. The water never stagnates and stays circulated and oxygenated, in constant contact with the stems held by your discs. There is no grow medium, so nothing that can suffocate or rot, and nothing to buy again with each batch. This is the principle of bubbler cloners, simple and forgiving of oversights. A power cut of a few hours has no consequence for your cuttings, as the cut ends stay immersed in the 13 litres, which clearly sets this model apart from the 72. So there is only one thing to keep an eye on with this tank, the steady bubbling of the two lines, and a clogged air pipe can be rinsed with clear water in a few seconds. Place the pump above the level of the tank, otherwise a power cut may cause water to flow back up the air pipe to it.

The tank

It holds 13 L, with its lid pierced with 27 slots. The volume is enough to limit swings in the water temperature.

The pump

It is a 4 W air pump delivering 3.5 litres of air per minute, with two distribution lines. It runs continuously.

The discs

There are 27 soft neoprene discs of 5 cm. You slip the stem in through a slit, and they can be rinsed and reused.

On the 72 model

The tank goes up to 70 L, the positions to 72, and the air pump gives way to a 12 V motor that drives a spray head.

🌀 The rotating head, 72 cuttings

In the centre of the large tank, a 12-volt low-voltage motor drives a spray head that throws the solution out as it rotates. The rotation solves a specific problem: with 72 positions arranged in a circle, fixed nozzles would water unevenly, the nearest ones too much and the furthest ones not enough. As it turns, a single head covers all 72 positions equally. Your cutting bases then stay in air saturated with moisture instead of sitting in water, a set-up that speeds up root formation markedly compared with bubbling. The 13 W motor runs on 12 volts behind a transformer, so no dangerous voltage comes into contact with the water.

A disinfected tank and water below 20 °C

Biofilm is a slimy bacterial deposit that forms on the walls and on the stems, and that makes the cut bases rot. Start each batch in a disinfected tray with clean water, and keep your water below 20 degrees. Beyond that, bacterial growth becomes faster than root formation.

What comes after the cloner

Your rooted cuttings are waiting for a growing system. An aeroponic pot with 5 cm baskets takes a neoprene disc directly, and the cuttings from the 72 model can be transplanted into the 8 cm baskets of the GrowStream gutters.

⚡ The trade-off of the 72 model

This speed comes at the price of a dependence on misting. A bare cutting base, with no grow medium or water around it, dries out in 1 to 2 hours if the head stops. The unit is designed for continuous operation, day and night, and a quick glance at the rotation each time you pass is the most useful maintenance habit for this equipment. Provide a reliable socket, not an overloaded extension lead, and check that the head turns freely, as a deposit on its axis is enough to slow it down. The 27 model, for its part, tolerates the unexpected, which makes it the sensible choice for your first batch, while the 72 will serve you if you run batch after batch and already know your species.

⚪ The neoprene discs

A neoprene disc can be rinsed and reused, run after run, whereas a rockwool cube stays attached to the plant it has supported. It holds your stem without squeezing it, lets the crown through, and adds no organic matter to the water: nothing that could ferment. You can therefore start a new run with the same set of discs. Between runs, a wash in hot soapy water followed by a thorough rinse is enough, as neoprene copes poorly with concentrated bleach, which ends up hardening it. This way you will keep the same set for several seasons, and a split disc can be replaced without touching the rest: the 5 cm neoprene discs are also sold separately.

💡 Heat, light and hormone

Three things affect your success rate and are chosen alongside the cloner. The first is a rooting hormone, gel or powder, in which to dip the cutting. Next comes soft lighting, as a cutting needs light but cannot cope with strong intensity. The third is a stable temperature, around 20 degrees in the water, which a heat mat provides in a cool room. Our article on the indoor seedling space covers the same need for seeds. The quality of the cut matters as much as these three settings: a clean section made with a scalpel just below a node heals much faster than a stem crushed with secateurs.

📅 The recovery time

Allow 10 to 14 days for your cuttings on the 72 model and 14 to 21 days on the 27, with easy species and water at around 20 degrees. The timing depends far more on the species, the quality of the cut and the water temperature than on the equipment: mint roots in a week, rosemary takes twice as long. Watch the base of the stem rather than the calendar, as the white dot of the callus appears before the roots. After 3 weeks with nothing happening, remove the stem, as it generally will not root any more and its tissue feeds the biofilm. Always take a few more cuttings than the number of plants you are aiming for, since an extra slot costs you nothing and woody species take less readily than herbaceous ones.

27 or 72 cuttings?

Two capacities, but also two ways of bringing water to the stems. This table sets the two side by side.

Two capacities, but above all two ways of wetting the stems The small one keeps the roots in the water, the large one mists them with a rotating head. A power cut is not the same experience in each case.

Frequently asked questions

10 questions

6 key questions, 10 in the detailed view

27 or 72 cuttings: which should you choose?

They are two sizes, and above all two different principles.

Point	HydroCloner 27	Spinner 72
Principle	hydrogen peroxide	spraying
Sites	27	72
Tank	13 L	70 L
Drive	4 W air pump	12 V motor
Tolerance to failure	several hours	1 to 2 hours
Weight	2.86 kg	11.8 kg

The 27 is a gardener's tool, forgiving and light. The 72 is a production tool: faster, bulkier, and with no margin in the event of a stoppage.

Do the two models work in the same way?

No. The 27 model is a tank of water that an air pump keeps moving and oxygenated: the base of the stems sits in water. On the 72 model, nothing sits in water: a rotating head sprays the solution onto the bases suspended in mid-air, which spend their time in air saturated with humidity. This is aeroponics in the strict sense.

The practical consequence is that the 72 roots faster, because the emerging root has both water and oxygen. In return, it depends entirely on its motor, whereas the 27 keeps its water even when switched off.

How long does a cutting take to root?

Do you need rooting hormone, and a humidity dome?

Rooting hormone is not needed for every species, and it is your species that decides. On easy plants such as mint, basil and tomato, a clean cut and clean water are enough. On woody stems or slow-rooting plants such as rosemary, bay and fig, it makes a clear difference to the result: it is then the first purchase to make alongside the cloner.

The dome is optional: the base of the stems is already in water or in saturated air, and it is the foliage that the dome protects from drying out. If kept closed all the time, it encourages mould, so it should be aired every day. What matters more is to reduce the leaf surface by cutting the leaves in half, to limit evaporation while the roots form.

Should you put fertiliser in the water?

5.5recommended low pH

6.0recommended high pH

Use very little, or none at all, during the first few days: a cutting without roots absorbs almost nothing, and an overly concentrated solution will burn it. Clear water, possibly with a very dilute rooting stimulant added, is enough. The pH matters more than the concentration, and our article on pH regulation explains how to measure it.

The water turns slimy or cloudy: what should you do?

This is a bacterial biofilm, the most common cause of failure when rooting cuttings hydroponically. It shows on the walls and at the base of the stems, and makes the cuttings rot within 2 to 3 days.

It has three causes, in order of frequency: water that is too warm, a tray that was not cleaned properly at start-up, and plant debris that has fallen to the bottom. The remedy is to empty, disinfect and rinse the tray, start again with clean water, and keep an eye on the temperature.

The threshold is 20 degrees in the water: above that, bacteria multiply faster than roots can form. An ambient air temperature of around 22 degrees is fine, and in a cool room a heat mat under the tray steadies the whole setup by avoiding swings between day and night.

Is light needed during rooting?

Does the model 72 run continuously, and is it noisy?

It runs continuously, day and night. The system has no timer and doesn't need one: continuous misting is what keeps the tissues hydrated.

A motor turning non-stop and misting inside a 70 L tank therefore makes more noise than an air pump, so install the model 72 in a utility room, a garage or a laundry room rather than in a bedroom. The model 27, by contrast, makes only the quiet hum of its air pump, which sits beside the tank.

Can it be used for seedlings?

What should you do with cuttings once they have rooted?

Wait until the roots are 3 to 5 cm long: shorter, they break at transplanting; longer, they tangle.
Take out the disc with its cutting, then gently remove the disc by spreading the slit.
Transplant into the destination system, a basket filled with clay pebbles or a pot.
Keep the air humidity high for the first two days, while the roots settle in.

The neoprene discs can be reused for another batch: rinse them in clean water, and give them a dip in very dilute bleach between batches if you have had a hygiene problem. This is what sets this system apart from rockwool propagation, where every cube is lost.
