Four planter boxes stacked on a 30 by 28 in base, reaching 63 in tall. Each box measures 27 by 9.5 by 7.5 in and carries up to 55 lbs, so this is not a token display rack but four full growing containers, spacious enough that a variety of plants can share one frame with room to develop. Going vertical is what makes that possible on a footprint under 3 ft square, and stacking the boxes in tiers also means each one sits clear of the one above and takes direct light rather than living in shade. Every box lifts out of the frame on its own. Replanting happens at a bench or a tap instead of on hands and knees at the unit, and a box that finishes its season can be swapped without disturbing the other three. Drainage holes in each base stop water accumulating in the soil, which is the failure that quietly kills plants in containers that hold everything they are given. The frame is a robust heavy metal structure carrying the stacked load, and the PE boxes are waterproof and light, so a loaded box is manageable and an empty one weighs almost nothing. Cleaning is a rinse. The whole assembly comes to 19 lbs, goes together with the included instructions and complete parts, and its concise lines suit a yard, patio, balcony or garden.
