Spider Farmer 4-Pot Self-Watering Gravity-Fed System Kit

The Spider Farmer 4-Pot Self-Watering System provides a complete, power-free automatic irrigation solution for grow tents, greenhouses, and indoor gardens. Operating entirely on gravity without pumps, electricity, or mains water pressure, this passive sub-irrigation kit utilises high-capillary wick lines to deliver a steady, on-demand water and nutrient supply directly to plant root zones.

The system features four heavy-duty pot bases equipped with elevated reservoir plates, keeping fabric pots elevated above standing water to prevent root rot, algae formation, and water stagnation. Capable of supporting heavy containers up to 59 kg (130 lbs) each, the bases accommodate fabric grow bags up to 7 gallons (26.5L) in capacity. Connected via flexible silicone tubing and a central shut-off valve box to a high-capacity 50-litre folding water reservoir, the setup provides up to two weeks of continuous, automated hydration for a 4-pot arrangement.

Ideal for 4×4 ft (1.2×1.2m) and 5×5 ft (1.5×1.5m) grow tents, this all-in-one kit includes 5-gallon fabric grow bags, wick cords, silicone hose, and a shut-off valve assembly. By supplying moisture via bottom-wicking, it encourages deep, healthy root development, prevents over-watering, and eliminates daily manual irrigation routines.

Key Benefits:

• Zero Electricity Required: Pure gravity-fed operation requires no power outlets, water pumps, or mains pressure connection.

• Elevated Anti-Algae Reservoir Plates: Suspends grow bags above standing water to preserve oxygenation and prevent algae or root rot.

• Heavy-Duty Weight Capacity: Each base supports up to 59 kg (130 lbs), making it suitable for large containers and dense living soil substrates.

• Accommodates Large Fabric Pots: Designed to fit fabric grow bags up to 7 gallons (26.5L) for maximum root volume.

• Extended Hydration Capacity: The included 50L folding reservoir provides approximately 2 weeks of automatic watering for 4 pots (or 1 month for 2 pots).

• Ideal Tent Sizing: Designed for clean layout inside standard 4×4 ft (1.2×1.2m) and 5×5 ft (1.5×1.5m) indoor grow tents.
