Spider Farmer Self-Watering System - 4-Pot Kit (50L Reservoir)

The Spider Farmer 4 Self-watering System keeps up to four fabric pots evenly watered without a pump, timer or power point. A 50L folding reservoir feeds each self-watering pot base by gravity, so the growing medium stays moist between top-ups. It works best once your plants have well-developed roots — seedlings have shallow roots that may not reach the moist soil, so wait until they are longer and stronger before moving them across. Why growers choose the Spider Farmer self-watering system No power needed: the system runs on gravity alone — no pump, timer or water pressure — so you can set it up anywhere in the tent. Fewer top-ups: a single 50L fill lasts around two weeks across a four-pot setup, or roughly a month across two pots. Even moisture: the reservoir feeds each pot base steadily, keeping the medium consistently moist between fills. Healthier roots: the reservoir plate lifts the fabric pot above standing water, preventing stagnation and reducing algae. Built to last: engineered for durability across multiple growing seasons.
