*Please Note- Flexitanks For The System Sold Separately
Transform your hydroponic growing environment with the Alien Flood & Drain PRO Silver Series, a high-performance Ebb & Flow system engineered for efficiency, scalability, and optimal root development.
Built with premium features—including heat‑reflective Silver Polymer pots, fabric pot inserts, and Dual‑Flow™ 50 mm fittings—this system delivers fast cycle times, virtually silent operation, and complete pot drainage for maximum oxygen exposure and nutrient uptake.
Designed for growers of all levels, it offers a simple plug-in and grow setup that supports any growing medium, from clay pebbles and coco mixes to soil blends. Automated flooding and drainage, powered by a Grasslin timer, maintains precise nutrient control across various plant types and stages.
The included AquaGuard moisture‑retention layer plays a vital role in enhancing root health: it slows evaporation, encourages roots to penetrate the full soil volume, and reduces watering frequency—resulting in fuller, more robust plant growth.
Why choose Alien Flood & Drain?
Provides a consistently oxygen-rich root zone, preventing root rot and enhancing nutrient uptake via automated drainage cycles.
Modular and expandable to suit any grow space configuration—making it ideal for small-scale use or larger setups.
Minimises monitoring and maintenance needs—quiet, water-efficient, and easy to operate.
