DWC Hydroponics System with Top Drip Kit 7 Gallon 4 Buckets

Spider Farmer’s 4-bucket DWC Hydroponics Grow System pairs four 7‑gallon square reservoirs with an adjustable top‑drip ring to speed early root establishment, then transitions to full deep‑water culture. Each bucket includes a 6-inch net cup, water‑level sight tube and triangular access cover for easy topping-up and measurement. An included air pump drives four air stones and the drip manifold, supplying up to 28 L/min of aeration for oxygen‑rich nutrient solution. The kit ships with 12 m of 4/6 mm tubing, clay pebbles, and all fittings for a plug‑and‑grow setup. Capacity is 7 gallons (about 26.5 liters) per bucket; no electronic sensors or controllers are included in the base kit. Designed for tents 90 cm wide when placing four buckets side by side.
