A built-in reservoir is what removes the daily watering round from this 3-tier planter. Water held below the soil is drawn on as the plants need it, and six drainage holes keep soil humidity steady rather than letting it swing, while a removable tray catches what comes through so the unit works indoors as well as out. Six container boxes sit across the three tiers, each 18.5 by 6.5 by 6 in inside and rated to 22 lbs, so six plant types can run side by side, and tiering them means every layer absorbs enough sunlight instead of the lower boxes living in shade. The boxes are 100 percent new PP, waterproof and crack resistant. Beneath them, a large carbon steel shelf measuring 24.5 by 23 in holds up to 44 lbs of gardening tools within easy reach. The frame is heavy duty, rustproof and non-deformable, and a triangle structure widens the stance to hold a 38 by 23 by 47 in unit steady once it is loaded. Four universal wheels move it, and the two rear wheels lock for a steady stop. The working height is set so tending the boxes does not mean squatting continuously, which is where the fatigue and back pain of a ground-level bed come from, and the wheels mean the whole planting travels rather than being tended where it happens to stand. At 34.5 lbs it suits balconies, patios, backyards, decks and apartments.
