Floor and bench space is the constraint that decides how much a greenhouse can grow. This hanging basket for hydroponics equipment answers it by stacking: three moulded tiers lock on top of one another so that a single footprint carries three separate growing levels, each with its own planting openings angled outward and upward. A bay that could hold one flat pot now holds three, and the plants themselves are not competing for the same light plane.

The tiers are arranged so that each level overhangs the one below it. That is what allows full-size plants on the bottom tier to grow up between the openings of the tier above rather than being shaded out by it.

The stacked tower hangs from a single central chain rather than three separate cords. One pick-up point makes the whole unit swing as a rigid body instead of twisting tier against tier, and it also means that lowering the tower for planting or harvest is a single movement. The base tray that sits under the bottom tier collects run-off, so the water from three tiers does not end up on the floor below.

Because the tiers separate, the tower is filled level by level from the bottom upward. That order matters: filling the top first makes the stack top-heavy and awkward to lift into position.

The angled openings suit two different plant habits. Trailing subjects such as pansies, trailing petunias and ivy spill out of the openings and down the tower, which is how the planted tower in the images above is being used. Upright crops planted at the top tier grow up through the middle, which is where taller flowering stems such as the iris and stock in the first photograph are set.

For protected cultivation the tower is also used with a free-draining medium or with a nutrient film arrangement, which is why it is specified as hydroponics equipment. Whichever route is taken, the same two rules apply: keep the medium from staying waterlogged at the base, and leave enough gap between towers for air to move through the canopy.

Working out a bay is a matter of spacing rather than area. Towers are normally hung in rows along the same overhead line, spaced so that the planted footprint of one does not touch the next; a common starting point is to leave a gap at least half the tower diameter between units so air can circulate. The colour range is shown in the images above, with grey and terracotta popular for ornamental planting and orange for retail displays. The tower is ordered together with the rest of the greenhouse equipment range, and growers setting out a vertical bay usually combine it with planting tools and bench systems. Where towers hang above working benches, many projects pair them with a multi-layer growing bench so that overhead and bench zones are served by one irrigation line. Vertical and hydroponic growing practice is documented by the FAO, and commercial growing technique is covered by Greenhouse Grower.

Q: Do the three tiers come apart for planting?
A: Yes. The tiers separate, and the tower is filled level by level from the bottom upward so the stack does not become top-heavy before it is lifted into position.

Q: Why does the tower hang from one central chain rather than several cords?
A: A single pick-up point keeps the stack moving as one rigid body instead of twisting tier against tier, and it makes lowering the whole tower for planting or harvest a single movement.

Q: Is there a tray to catch water from all three tiers?
A: A base tray sits under the bottom tier and collects the run-off, so water from the upper levels does not reach the floor below.

Q: Can it be used as a hydroponic tower rather than with compost?
A: It can be used with a free-draining medium or with a nutrient film arrangement, which is why it is listed as hydroponics equipment. Whichever is used, keep the base from staying waterlogged.

Q: How far apart should the towers be spaced in a bay?
A: Spacing matters more than area. Leave a gap of at least half the tower diameter between units so air can move through the canopy and the planted footprint of one does not touch the next.

Q: What plants suit the angled openings?
A: Trailing subjects such as pansies, trailing petunias and ivy spill out and down, while upright flowering stems planted at the top tier grow up through the middle of the stack.
