The CultiMate is a soilless growing pot that sits on its own reservoir: 15 L for a medium-sized plant or a herb, 45 L for a large specimen, or two more compact plants, with greater autonomy. An air pump lifts the nutrient solution up to a ring that waters the plant continuously, with no water pump or timer, and the 45 L solar version works where there is no power socket.

The summary

What it is: a soilless grow pot sitting on its own reservoir, for one plant in the 15 L, or one or two in the 45 L. An air pump brings the solution and oxygen up continuously, with no water pump.
Three versions: a 15 L reservoir for a balcony or a medium-sized plant, a 45 L for a large plant and more autonomy, and a 45 L solar version for growing where there is no power socket.
Nothing to programme: it runs continuously, and no electrical part touches the water.
Your routine: a top-up every 2 to 4 days on the 15 L in midsummer, every 1 to 2 weeks on the 45 L.
What you choose to go with it: about 25 L of clay pebbles for the 45 L, a complete hydroponic nutrient and the means to read the pH.
Dimensions: 31 x 31 x 38 cm for the 15 L, 47 x 47 x 43 cm for the 45 L.

A 15 or 45 L reservoir beneath the plant, continuously irrigated by an air pump

The CultiMate hydroponic pot places a plant on its own 15 or 45 L reservoir: the 15 L suits a medium-sized plant or a herb, the 45 L a large plant or two compact ones. An air pump waters the roots continuously, with no water pump. The 45 L solar version runs without a mains socket.

This grow pot sits a plant on its own reservoir, in 15 or 45 L. The mechanism is the same in both volumes, right down to the pump. What changes comes down to one figure, since there is three times more solution beneath the plant, and therefore three times more autonomy between refills.

💨 Air emulsion

This system works without a water pump. A small air pump sends air to the bottom of a column submerged in the reservoir. The rising bubbles carry the nutrient solution up with them, to a perforated ring placed above the growing pot, from where it falls as a fine rain onto the clay pebbles. It passes through the grow medium, waters the roots on the way, and returns to the reservoir. This is the principle of the air-lift, as used in aquarium filters, in which the only moving part is the pump's diaphragm, which is therefore also the only wear part in the system.

The reservoir

It comes in 15 or 45 L, with a clear level tube on the side. Filled, the 45 L weighs about fifty kilos.

The pump

It is a 1.8 W air pump delivering 1.3 litres of air per minute, the same on both volumes. Its diaphragm can be replaced.

The grow chamber

It is a perforated basket that holds the grow medium and the plant. Allow about 25 L of pebbles for the 45 L one, and 10 L for the 15 L one.

The circuit

Pump column, strainer, pierced distribution ring, tubes and seals. No electrical part comes into contact with the water.

🪴 Which volume for which plant

The 15 L pot takes one plant, the 45 L pot one or two, and since the whole solution is shared, two plants in the same pot must have the same needs. You install the plant already rooted, as a plug or a cutting that has taken, and wedge it in the clay pebbles. The 15 L suits a herb, a cut-and-come-again lettuce, a chilli pepper or a strawberry plant. The 45 L holds what the smaller volume struggles to sustain: a full-size tomato, cucumber, aubergine or sweet pepper, a plant meant to stay with you for the whole season. The guide what to grow in hydroponics details the cycles.

Before filling, three precautions

Three precautions will save you from losing a crop right from the start. Do not move the pot once it is filled, because 45 L of water plus the wet grow medium come to around fifty kilos and the level tube will break the first time it is moved clumsily. Do not fill above the upper mark on the tube, otherwise the solution drowns the crown and the stem rots at the level of the pebbles. Do not pour in unrinsed clay pebbles, since the dust settles in the strainer and blocks the distribution ring.

Pot, grow medium and nutrients in a single order

If you are starting from scratch, the 45 L pot pack brings together the pot, the grow medium, the nutrition and the pH control in a single order, so you have no grow medium, nutrition or pH test to choose separately. To run several pots together, the constant-level reservoir links them to a single filling point.

Volume also affects your margin for error. A large reservoir cushions swings better: the pH changes more slowly, the salt concentration rises more slowly through evaporation, and a dosing mistake is diluted rather than burning the roots. In summer, with a plant in full production, this reserve needs topping up every 1 to 2 weeks, whereas the 15 L reservoir needs a top-up every 2 to 4 days.

☀️ The solar version

A south-facing balcony, a greenhouse at the bottom of the plot or a shared patch with no electricity, and solar becomes the only way to circulate the solution. The solar pump delivers 2 litres of air per minute at 8 volts, and its panel is staked into the ground on an adjustable post, connected to the pump by 3 m of cable. It runs on whatever sun there is, which is enough for a clay pebble grow medium, as moisture stays in it for several hours after the last irrigation. If you have a socket next to the pot, the mains version is simpler, and its power consumption is negligible. Factor the panel into your layout from the start, since it needs full exposure all day, which is not always the spot where you wanted to put the pot.

🧪 pH and top-up water

In a closed circuit, the pH shifts as the plants consume nutrients. The working range is 5.8 to 6.2, and it is the reading you will take most often. The article on pH regulation applies here too, and the correction can be bold since no fish live in this reservoir. On 45 L it shows up more slowly than on 15, so let it run for an hour before measuring again.

Topping up the water follows the same rhythm as the plant. Allow a top-up every 2 to 4 days for 15 L in midsummer, and every 1 to 2 weeks for 45 L, and read the transparent tube rather than opening the pot. Top up with plain water as long as the conductivity stays within its range, since it is the water that evaporates and not the salts, and make up the whole solution afresh when the difference becomes clear. A complete change every 2 to 3 weeks is a good guideline for a plant in full production, and it saves you from chasing an imbalance that topping up with water can no longer correct.

🔧 Routine maintenance

This system asks for little, and what matters most is the air pump. Its diaphragm wears with the hours of continuous running, and the warning sign is a weaker spray at the outlet of the ring rather than a sudden stop. Place the pump above the level of the solution, otherwise a power cut can make the solution flow back along the air line to the pump. The distribution ring can also be replaced individually, if it cracks or if its holes stay blocked despite soaking in vinegar. Finally, rinse the strainer and the distribution ring at every change of crop, since a deposit of salts is enough to reduce the flow without being visible from outside. Soaking overnight in vinegar water restores the holes of a scaled-up ring, and you will thus avoid buying a new one.

Which reservoir?

Same pump, same principle: the reservoir, its growing chamber and the feed are what change.

The available power decides, and the reservoir covers your absences Only the solar version needs no mains socket. As for the two tanks, what decides is how long you want to leave between refills.

Frequently asked questions

10 questions

6 key questions, 10 in the detailed view

15 L, 45 L or 45 L solar: which should you choose?

The principle is the same in all three cases. What changes is the volume of the reservoir, and therefore the running time between refills and the size of plant you can grow, as well as how the pump is powered.

Feature	15 L	45 L	45 L solar
Reservoir	15 L	45 L	45 L
Running time in summer	a few days	1 to 2 weeks	1 to 2 weeks
Footprint	31 x 31 cm	47 x 47 cm	47 x 47 cm
Power socket	required	required	not needed
Circulation at night	yes	yes	follows the sun
Empty weight	3.05 kg	6.73 kg	7.7 kg

Indoors, or on a terrace with a power supply, the choice comes down to the space available and the size of the plant. The solar version is the one to pick if you want to be free of the cable, as the mains pump's power consumption is negligible.

How many plants can you put in it, and which ones?

The 15 L pot takes one plant, the 45 L pot one or two. The whole solution is shared, so two plants grown together in the same pot must have the same needs.

15 L tank: it suits basil, parsley, chives, mint, chilli, dwarf pepper, cut-and-come-again lettuce and strawberry. It is suitable for one medium-sized plant with a short or medium cycle.
45 L tank: it suits one tomato, aubergine, cucumber, courgette or pepper plant meant to last a whole season, or two more compact plants of the same species. The volume copes with the evaporation from heavy foliage in midsummer.
In both cases, avoid plants with storage roots, carrot, radish, beetroot, and perennial shrubs, which end up filling the basket with woody roots.

Is there anything to programme?

How often does water need topping up?

2 to 4 d15 L reservoir, large foliage in summer

1 to 2 wks45 L reservoir, same plant

This is the only daily difference between the two sizes, and it is decisive if you go away. The level tube on the side of the pot can be read at a glance: top up with plain water as long as the solution is not too old, and make up the whole solution afresh every 2 to 3 weeks. In winter, or with a small plant, these intervals easily double.

On the solar version, what do you receive, and does the pump run at night?

The solar pump works with the sun: circulation follows the daylight and stops at night.

On this type of system, the overnight interruption has no real consequence, as the clay pebbles hold their moisture for several hours. In a heatwave, a hot night without circulation is felt more. If your crop cannot tolerate any interruption, choose a mains-powered version, where the pump runs 24 hours a day.

The pot, its growing chamber and its circuit are identical to the mains-powered version. Only the power supply changes: the air pump is replaced by a 2 L/min solar pump, powered by 8 V direct current from a photovoltaic panel mounted on an adjustable stake, connected to the pump by a 3 m cable.

Can the solar version stay outside over winter?

The pot and its panel are designed for outdoor use, and there is no need to bring them in before the first frosts. What won't survive the winter is the water in the reservoir: 45 litres of freezing water will burst the fittings and crack the level tube.

Winterising takes three steps: empty the reservoir completely at the end of the growing season, unplug the pump and store it somewhere dry, and leave the pot in place with its lid on. The photovoltaic panel can stay outside without any harm. During the season, shelter the pump and its connection from driving rain.

Keep the lid in place all year round as well: rain getting in dilutes the solution and changes the pH without you noticing. Check the level after a heavy storm.

Which grow medium should go in it?

Use expanded clay pebbles, 8 to 20 mm grain size, rinsed before use. They hold almost no water, which is exactly what you want here: it is the circulation that supplies the water, and the grow medium only holds the plant and lets air through.

Rockwool and coco fibre also work, but they retain more: make sure the grow medium is not permanently waterlogged. The article on choosing a grow medium sets out the trade-offs.

The pump runs day and night: what does it cost to run, and is it noisy?

1.3 kWhper month, mains versions

0 kWhsolar version

The air pump is rated at 1.8 W and runs continuously, which comes to about 1.3 kWh per month. The 45 L reservoir costs no more to run than the 15 L one: the pump is the same. On the solar version, circulation costs nothing, but the air flow follows the sunshine.

As for noise, it gives off a discreet hum, comparable to that of an aquarium air pump. Placed on a foam mat rather than directly on a shelf, the pump fades into the background; placed on a hollow surface, it resonates. The noise comes from the diaphragm, not the water: the pot itself is silent.

Algae are appearing in the reservoir, what should I do?

The reservoir looks like an aquarium, can fish be kept in it?

The resemblance stops at the volume. At 45 litres, the reservoir is the size of a small aquarium, but it lacks everything that makes an aquarium habitable: no biological filtration, no exchange surface, and above all a mineral fertiliser solution dosed for plants, which is not water suited to keeping fish.

If the idea of keeping plants and fish together appeals to you, aquaponics is the way to go, with equipment designed for it.
