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

The HydroCloner hydroponic cloner from Terra Aquatica roots cuttings without soil or consumables, as its neoprene discs can be washed and reused. It comes in two sizes: 27 sites on a 13 L tank oxygenated by an air pump, or 72 sites in aeroponics on a 70 L tank, with rooting in 10 to 14 days.

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 feeds air into the 13 L tank through two lines. The water never stagnates and stays stirred and oxygenated, in permanent 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 for each batch. This is the principle of bubbler cloners, simple and forgiving of oversights. A power cut of a few hours has no consequences for your cuttings, as the cut bases remain submerged in the 13 litres, which clearly sets this model apart from the 72. You therefore only have one thing to watch on this tank, the steady bubbling of the two lines, and a clogged air pipe is rinsed in 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 through 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

At the centre of the large tray, a 12-volt low-voltage motor drives a spray head that throws the solution as it rotates. The rotation solves a specific problem: with 72 positions arranged in a circle, fixed nozzles would water unevenly, the closest ones too much and the furthest ones not enough. By rotating, a single head covers all 72 of your positions equally. Your cutting bases then sit in air saturated with moisture instead of soaking, a setup that speeds up root formation noticeably 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

A rooted cutting then moves on to a growing system. A 5 cm basket aeroponic pot takes a neoprene disc directly, and a cutting removed from its disc can be transplanted into an 8 cm basket filled with clay pebbles, like those of the GrowStream gutters.

⚡ The trade-off of the 72 model

This speed comes at the price of a dependence on the misting. A bare cutting base, with no grow medium or water around it, dries out in 1 to 2 hours if the head stops. It is designed to run continuously, day and night, and a quick look at the rotation each time you pass is the most useful maintenance habit with this equipment. Provide a reliable socket, not an overloaded extension lead, and check that the head turns freely, as a deposit on its shaft is enough to slow it. The 27 model, by contrast, 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, batch after batch, whereas a rockwool cube stays attached to the plant it has supported. It holds your stem without squeezing it, lets the collar through, and adds no organic matter to the water: nothing that could ferment. You can therefore start a new batch with the same set of discs. Between batches, a pass through hot soapy water followed by a thorough rinse is enough, as neoprene copes poorly with concentrated bleach, which eventually hardens it. You will therefore 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. The article on the indoor seedling area 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 by secateurs.

📅 The recovery time

For your cuttings, allow 10 to 14 days on the 72 model and 14 to 21 days on the 27, with easy species and in 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 3 weeks or more. Look at the base of the stem rather than the calendar, as the white dot of the callus appears before the roots. After 3 weeks with no callus on a herbaceous species, remove the stem, because it will generally no longer root and its tissues feed 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?

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

Point	HydroCloner 27	Spinner 72
Principle	hydrogen peroxide	misting
Sites	27	72
Tank	13 L	70 L
Drive	4 W air pump	12 V motor
Failure tolerance	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 if it stops.

Do the two models work in the same way?

No. Model 27 is a water tank that an air pump keeps moving and oxygenated: the base of the stems sits in the water. On model 72, 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 available. 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 species, such as mint, basil and tomato, a clean cut and clean water are enough. On woody stems or those slow to root, such as rosemary, bay and fig, it makes a marked difference to the result: it is then the first purchase to make alongside the propagator.

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. Kept closed all the time, it encourages mould, so it should be aired every day. What matters more is to reduce the leaf area by cutting the leaves in half, to limit evaporation while the roots form.

Should you put fertiliser in the water?

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

It 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 rots the cuttings in 2 to 3 days.

It has three causes, in order of frequency: water that is too warm, a reservoir not cleaned properly at the start, and plant debris that has fallen to the bottom. The remedy is to empty, disinfect, rinse, 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 form. An ambient air temperature of around 22 degrees is fine, and in a cool room a heat mat under the reservoir keeps everything stable 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 a spray inside a 70 L tank therefore make more noise than an air pump: install the model 72 in a utility room, a garage or a laundry room rather than in a bedroom. The model 27, on the other hand, only makes the quiet hum of its air pump, which sits next to the tank.

Can it be used for seedlings?

What should you do with cuttings once they have rooted?

Wait until the roots reach 3 to 5 cm: shorter, and they break at transplanting; longer, and they tangle.
Lift out the disc with its cutting, then carefully remove the disc by opening the slit.
Transplant into the destination system, either 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, for their part, are ready for another batch: a rinse in clean water, and a pass through very dilute bleach water between batches if you have had a hygiene problem. This is what sets this system apart from rockwool propagation, where every cube is lost.
