Everything you need in one box, and that changes a lot. Building an indoor growing space piece by piece means choosing a tent, then a lamp sized for that tent, then a shelf that fits inside it, then trays that fit on the shelf. Here, everything is matched in advance: the frame, the three levels, the six light bars and the mats are designed for one another.

The format is its main argument. Forty centimetres wide by thirty deep, for a metre twenty tall: it flattens against a living-room wall, it fits in an office corner, it works in an apartment with no basement and no garage. It's the solution for people who have no space to sacrifice and still want to start their seedlings, keep fresh herbs through winter or grow microgreens year-round.

The details that matter in use: the shelves are adjustable, top layers included, which lets you set the distance between lamp and plants as they grow — the single most important adjustment in indoor growing. The front door is transparent, so you check without opening and without dropping the temperature. And the tent is high-density Oxford fabric, which keeps the light inside, as much to send it back toward the plants as to avoid lighting up the living room at ten at night.
