A complete watering solution combining top-feed drip irrigation with automatic drainage. Ensures consistent watering, prevents standing water, and keeps roots healthy in grow tents, greenhouses, balconies, and indoor gardens. This combination kit features a 250ml/s high-flow drip pump with 8 fully adjustable drippers (0-100%) for precise irrigation, and a 200ml/s high-flow drainage pump (with a 5m head ) to automatically remove runoff. It creates a Drain-to-Waste (DTW) ecosystem, perfectly suited for soilless cultivation in inert media (like coco coir, rockwool, or clay pebbles) and hydroponic setups. It ensures fresh nutrient delivery while instantly removing runoff to prevent salt buildup and root rot. If you need additional drainage trays, click to add the 2-pack refill.
