Five levels, two hundred and twenty watts, a metre eighty tall: this is no longer a supplementary greenhouse, it's a real production shelf, in a floor footprint forty centimetres deep.

It's the best growing-surface-to-floor ratio in our whole range. A square 120 × 120 cm tent takes up 1.44 m² of floor for a single growing surface. This shelf takes up 0.44 m² and offers five. When what's missing isn't light or money but floor, it's mathematically the best answer. It flattens against a basement wall, a heated garage, even a hallway.

What it makes possible: five levels of trays is a staggered microgreen production where each level is at a different stage and you harvest something every week. It's also a spring nursery capable of supplying a large vegetable garden, or a combination of both: seedlings on top, herbs in the middle, microgreens below. The ten 22 W bars spread light level by level, and the shelves are adjustable, top layers included, to follow the growth.

The transparent front door lets you check without opening, and the tent is high-density Oxford fabric, which holds the light inside instead of letting it light the room.
