The summary

What you receive: the tower and its 6 tiers, the supporting frame and its 4 LED bars, the 12 V submersible pump with its mains adaptor, a water level indicator.
How the water circulates: the pump lifts the solution to the top, it flows down tier by tier past the roots, then drops back into the reservoir.
How much daily effort: a water top-up every 3 to 4 days at full load, a rinse of the circuit between two cycles.
Where to put it: a room that gets no direct sunlight, where the LED bar replaces the window.
What it is designed for: leafy greens and herbs, lettuce, rocket, basil, chives, and strawberries.
What is sent to you: a 63 × 31 × 27 cm box, tower dismantled with its fixings, to a pick-up point or to your door.

Indoor growing tower, 30 slots over 6 tiers, light and pump included

The 30-plant indoor hydroponic tower with LED lighting is used to grow leafy greens and herbs in a room without direct sunlight, such as a kitchen, a hallway or an office. It offers 30 planting positions over 6 levels and supplies its own light, with 4 LED bars. The submersible pump and mains adaptor are included.

This tower holds 30 planting positions over 6 levels and comes with its own lighting. A supporting frame surrounds it and holds 4 vertical LED bars, the submersible pump sits in the 10 L reservoir, and the mains adaptor powers the whole unit. It is designed for a living space where the sun does not come in strongly, such as a kitchen, a hallway or an office.

🔆 The built-in light

The light bar delivers around 2 to 3.6 moles of photons per square metre per day depending on how long it is switched on. A head lettuce needs 11.5 to 17, an indoor basil 8 to 10, and young rocket or mustard shoots 9 to 12. It is therefore a supplement, to be topped up with daylight. Place the tower near a window, even a north-facing one, and you enter the ranges that give firm leaves rather than leggy stems. A duration of 16 hours of lighting per day is the usual setting for leaf crops, and shortening it brings no benefit to the crop.

Lettuce and baby leaves

Their cycle lasts 4 to 6 weeks and you harvest the leaf. Place them on the upper tiers, which get the most light.

Basil

It is a full-sun plant: give it a top tier as well, and pinch it out every week to prolong the harvest.

Parsley, chives, mint

They make do with more moderate light and cope well on the lower levels, where illumination decreases.

Root crops and large fruiting plants

Carrot, beetroot and large-fruited tomato fail: the taproot hits the bottom of the basket, or the plant acts as a lever and snaps.

Fill all 30 positions as soon as it arrives

Order 30 perforated grow pots at the same time, one per position, together with peat germination sponges, which fit directly into them. You sow in the sponges, wait for the roots to show through, then place each sponge in its pot and the pot in the tower. A complete nutrient solution, such as the TriPart Grow growth fertiliser combined with TriPart Micro, then feeds your leaves and herbs from transplanting to harvest.

No potting compost or garden fertiliser in the tower

Do not put potting compost in the pots, as it clogs the tier distributors within a few days. Nor should you use a garden-centre fertiliser designed for soil: it dissolves poorly and does not supply calcium or trace elements in a form that a bare root can absorb. Finally, in a completely windowless room, the light bar alone produces leggy plants with thin leaves, so a window nearby is still necessary.

💧 The gravity-fed cascade

The principle is a gravity-fed cascade. The submersible pump lifts the nutrient solution to the top of the cylinder, the water flows down from tier to tier past the roots, then drops back into the base reservoir. There is no nozzle or misting, and nothing to carry up by hand. Each tier has 5 planting positions around its edge, which gives you 30 plants on a footprint of 39 by 39 cm, roughly that of a large stool. The details of how it works are in the grow tower guide.

🔧 Assembly and filling with water

The tower arrives unassembled, in a box measuring 63 by 31 by 27 cm, with its fixings and assembly instructions. First you assemble the supporting frame and its 4 LED bars, then you stack the 6 growing tiers above the reservoir and fit the top cover. The pump sits at the bottom of the reservoir, connected to the pipe that carries the solution up to the top. Then fill the 10 L, check the level on the indicator, and let the pump run for a few minutes, with the slots still empty, to check that every tier is trickling properly. Once assembled, the tower stands 97 cm tall, frame included: measure the clearance if you plan to put it on a worktop under wall cabinets, and allow for a socket nearby, since the pump and the light bar both need to be plugged in.

🚰 Topping up the water

Once fully grown, 30 lettuces use 2.4 to 3.4 litres per day, which means a top-up every 3 to 4 days at full load. With young plants, consumption is five to ten times lower and the reservoir lasts several weeks. As for electricity, it is the light bar that weighs in, not the pump: expect about 93 kilowatt-hours a year at 16 hours of lighting per day, against 61 for the pump running continuously, and only 15 if you run it for 15 minutes every hour with a daily timer. The noise, finally, comes from the water falling back into the reservoir and not from the pump, which is submersible: it is the sound of a small indoor fountain, constant. Keep the reservoir well filled: the drop height decreases, and the noise with it. Between top-ups, the conductivity of the solution rises as the level falls, since it is the water that evaporates and not the fertiliser: so top up with clean water, and replace the entire solution every 2 to 3 weeks, rinsing the reservoir at the same time.

🐟 Water from a fish pond

This tower can run on pond water, provided three conditions are met, in this order. Filter out solids upstream: a smooth plastic cascade column has no filter mat, and suspended matter settles in the tier distributors until it blocks them. Next, accept a compromise pH: aim for 5.8 to 6.5 in pure hydroponics, 6.4 to 7.5 with fish to look after the bacteria, and at the top of that range iron becomes less available, which a supplementary chelate corrects. Finally, increase the flow rate, which no longer has only to wet the roots but also to sustain nitrification. Then stick to leafy greens and herbs: pond water is low in potassium. The article on aquaponics and hydroponics explains what sets the two methods apart.

Frequently asked questions

10 questions

6 key questions, 10 in the detailed view

Are LEDs enough in a room with no window, and how many hours should they be left on?

They are not enough for hearting lettuces. The light bar delivers 2 to 3.6 moles of photons per square metre per day, whereas a hearting lettuce needs 11.5 to 17. In a completely windowless room, you will get plants stretched towards the lamp, with thin leaves.

With a window, even a north-facing one, the tower becomes very effective for herbs and young leaves: indoor basil grows properly from 8 moles per day, rocket and mustard between 9 and 12, and the extra light from the bar is enough to get past these thresholds.

Leave the light bar on for 16 hours a day, the usual setting for leaf crops. Shortening this period only reduces an amount that is already limited.

Which plants work in a tower, and which fail?

The deciding criterion is the shape of the root and the weight carried above the basket. The strawberry is a fruit and it succeeds, the beetroot is a root and it fails.

Crop	Verdict	Why
Lettuce, spinach, rocket, lamb's lettuce	yes	Short cycle, small fibrous root, you harvest the leaf
Basil	yes	A full-sun plant, to be placed on the upper tiers
Parsley, chives, mint	yes	More moderate light is enough for them, which suits the bottom of the tower
Strawberry plant	yes	Shallow root and little weight overhanging
Carrot, radish, beetroot, turnip	no	Taproot: the basket is 5 cm, so the taproot hits the bottom and becomes deformed
Tomato, aubergine, courgette	no	Several kilos acting as a lever on a 5 cm basket, and a light requirement out of reach here
Garlic, onion, potato	no	A cycle of 5 to 8 months, or a volume of grow medium out of all proportion to a basket

What difference does it make to have it in a living room, in terms of noise and electricity?

The sound is that of a small indoor fountain, and it is constant. It does not come from the pump, which is submerged, but from the water falling back into the reservoir after passing through the 6 tiers. Keep the reservoir well filled so the drop is shorter, and run the pump intermittently rather than continuously. In a bedroom, be aware that it will remain audible at night.

93 kWhLED light bar, 16 h a day

61 kWhpump running continuously

15 kWhpump running 15 min an hour

That comes to somewhere between 108 and 155 kilowatt-hours a year for the whole system. It is the lighting that weighs most: a timer on the pump cuts its share by a factor of four, and it deals with the night-time noise at the same time.

How long can I go away without topping up the water?

Why do the plants at the bottom stay smaller than those at the top?

Because they receive less light. In a vertical column, the light received and the fresh weight of the plants decrease from top to bottom. This is simply the geometry of a column, and the effect is milder here than on a tower lit only from the ceiling.

There are two practical answers. Keep the top for the most demanding plants, lettuces, baby leaves and basil, and the bottom for parsley, chives and mint, which are content with more moderate light. And rotate the tiers between two cycles, so that the same plants are not always the least well lit.

Which fertiliser should go in it?

You need a complete mineral nutrient solution, designed for soilless growing. A garden-centre fertiliser intended for soil is not suitable: it supplies neither calcium nor trace elements in a form that bare roots can absorb directly, and it dissolves poorly, which clogs the distributors.

A three-part fertiliser lets you follow the plant's stage: TriPart Grow growth fertiliser for foliage, TriPart Micro for trace elements, and TriPart Bloom if you are growing strawberries through to fruiting. Always dissolve the fertiliser completely before pouring it into the reservoir.

Are the grow baskets included?

Can I feed it with the water from my fish pond?

Yes, on three conditions, in this order.

Filter out the solids upstream. A smooth plastic cascade tower has no filtering bed: suspended solids settle in the tier distributors and block them.
Accept a compromise pH. In pure hydroponics the target is 5.8 to 6.5; with fish, the pH needs to be raised to between 6.4 and 7.5 to protect the bacteria. At the top of this range, iron becomes less available, and a supplementary chelated iron is often necessary.
Increase the flow rate. It no longer serves only to wet the roots, but also to sustain nitrification and carry away the fine particles.

Then stick to leaves and herbs: pond water is low in potassium.

How do you clean it between cycles?

Empty the reservoir and remove the baskets and any leftover roots.
Separate the 6 tiers, which come apart without tools.
Rinse each tier and the riser pipe with clean water, paying particular attention to the distributors.
Fill with clean water and let the pump run for 15 minutes to flush the circuit.
Reassemble, then fill with the new nutrient solution.

Allow 20 minutes. It is also a good moment to swap the tiers around and give the top of the tower to different crops.

Can it be put out on a balcony in summer?
