700er model: each box is 0.7 × 0.3 m (0.21 m² growing area), empty ≈ 3 kg. Pick your soil type to see the loaded weight. Drag the sliders or tap +/− to plan your space.
The narrower the aisle, the more growing area you gain. With trays on a sliding carriage the aisle can drop to zero — rows roll apart only when you need to step in, so almost no floor is wasted. Just leave a small slide-open gap.
