Built for homeowners turning a garage corner into a year-round salad source, urban apartment growers running a balcony farm, and STEM teachers needing a classroom-friendly plant lab, this 3-tier hydroponics growing system kit fits 108 planting sites into a 38.58 x 20.47 x 46.06 in. footprint - more output than a raised bed in a fraction of the floor area. Each UPVC pipe pairs a white reflective outer layer with a black inner layer to block light from the nutrient solution, stopping the algae buildup that ruins cheaper PVC rigs after one summer, and the thickened pipe walls resist cracking or warping across multiple grow cycles. The 4W water pump moves nutrient solution efficiently through every tier, and the 24-hour plug-in timer lets growers schedule automatic on/off cycles - water during work hours, rest overnight - without daily intervention. Pre-glued factory joints keep the lines leak-tight, while pre-assembled components and clearly marked pipes mean a first-time grower can stand the unit up using the included cable ties and rubber mallet without specialty tools. The 1.34 in. / 34 mm planting holes spaced at 3.15 in. accept 1.77 x 1.77 in. baskets and 0.98 in. sponge cubes, ready for lettuce, basil, cilantro, strawberries, leafy greens, and small herbs. At 28.22 lb. / 12.8 kg, the rig stays in place once positioned and turns a corner of the garage, greenhouse, or sunroom into a clean, soil-free harvest each week. Color: White exterior with black interior pipe.
