4-Tier Rolling Hydroponic Grow Rack — 12 Planting Tubes, 108 Plant Sites Mobile Vegetable Growing Kit

Robust Construction: Built from high-quality PVC-U using injection molding and extrusion molding methods for enhanced strength, wear resistance, and long service life. The rack uses a stable rectangular frame and thick tubing to support heavy loads safely. High-Performance Water Delivery: Equipped with a pump delivering a 55 Gal/h flow rate and a 6.56 ft pump head. Operating in a parallel flow hydroponics mode, it supplies oxygenated, nutrient-rich water directly to plant roots to promote faster growth and higher yields. Planting Capacity & Layout: Four tiers provide a total of 108 planting holes. Each hole measures 1.26'' with 3.31 inches center spacing, and the system includes 12 planting tubes to accommodate a compact indoor vegetable garden. Adjustable Pump Timer: The integrated water pump timer offers selectable ON intervals of 5/15/30min and OFF intervals of 30/60/120min, making automated irrigation simple and energy-efficient. Load Capacity & Mobility: Each tier supports up to 33.07 lbs. Four universal caster wheels with brakes allow easy relocation and secure locking when in position. Basic Planting Guide: 1. Soak seeds in water for 2 hours. 2. Place seeds in moist gauze until they germinate (keep gauze damp). 3. Wet the sponge by pressing it in water, fill it halfway, add nutrient solution (not included), and place germinated seeds into the sponge holes. Keep the sponge moist, in sunlight and ventilated. 4. Transplant once the plant has three or four true leaves. 5. Break the sponge into small pieces, place them in the planting baskets, and insert the baskets into the planting tube holes. Important Notes: Nutrient solutions, seeds, and other planting accessories are not included. A water tank is not provided—an approximately 6.6 Gal bucket at home can be used as a reservoir; an opaque container with a lid is recommended. Protect seeds from light prior to germination and add nutrient solution promptly after germination while keeping sponges moist. Ensure planting location receives at least 4 hours of direct sunlight daily or use grow lights if natural light is insufficient. Maintain adequate water level so the pump remains submerged to avoid damage. Install the unit on a stable surface and read the user manual carefully, paying attention to all safety instructions. Please allow slight color variation due to photography and a 1-3cm measurement tolerance.
