Introducing the ALIEN® Flood & Drain PRO 30l Silver Series System—a revolutionary solution in hydroponic cultivation designed to optimize plant growth and simplify your gardening experience. This system is engineered to prevent root blockages and ensure a consistent flow of nutrient-rich water to your plants, eliminating common issues like root clogging and reducing maintenance efforts.

Key Benefits:

• Efficient Nutrient Delivery: The system floods the grow medium with nutrient-rich water and then drains it, ensuring that plant roots receive a consistent supply of oxygen, nutrients, and water. This cycle promotes strong, healthy growth by providing everything the plant needs in balanced amounts.

• Oxygen-Rich Root Zone: The draining phase allows roots to breathe by exposing them to oxygen between flood cycles. This oxygenation helps prevent root rot, boosts nutrient uptake, and improves plant health and productivity.

• Reduced Risk of Overwatering: Unlike other hydroponic systems, the Flood and Drain system prevents overwatering by automatically draining the water, allowing plants to absorb exactly what they need without risking waterlogged roots.

• Versatile and Scalable: Flood and Drain systems can be easily customized for a range of plants and growing spaces, from small indoor gardens to large commercial setups. They work with various growing media and can be scaled up or down based on the grower’s needs.

• Cost-Effective and Low Maintenance: This system requires less frequent monitoring once set up. Fewer moving parts mean reduced maintenance and more reliable operation over time. No noisy air pump is needed, and there is a lower likelihood of needing a water chiller. The nutrient tank can be placed outside the grow room to help lower the temperature of the nutrient solution.

• Flexible Nutrient Control: With scheduled flooding, growers can control the timing and frequency of nutrient delivery, allowing precise adjustments for specific plant types, growth stages, and environmental conditions.

PRO Silver Series Features:

• SUS304 Stainless Steel Level Switches: Equipped with Hirschmann connectors, these switches are renowned for their reliability in commercial applications.

• Patent-Pending Dual-Flow™ Fittings: Oversized 50mm fittings provide a more free-flowing system, significantly reducing the risk of blockages.

• Heat-Reflective Silver 50mm Pipe: Helps maintain optimal nutrient solution temperatures by reflecting heat.

• Reliable Brain Module: Features the world-renowned Grasslin timer for precise control over flood and drain cycles.

• Heat-Reflective Silver Polymer Pots and Lids: These components help keep nutrient solution temperatures cooler, and the sloped base allows complete drainage.

• Jet-Stream Submersible Water Pumps: Ultra-quiet, low-profile design made from corrosion-resistant materials, including a stainless steel shaft and a grated base cover.

• AquaGuard Protective Layer: Maintains consistent soil moisture, encouraging roots to spread and grow up to the top of the soil, supporting robust root networks and better nutrient uptake.

• High-Quality Fabric Pot Inserts: Made of breathable fabric, these inserts allow for air pruning of the roots, promoting healthier root development.

The ALIEN® Flood & Drain PRO Silver Series System is perfect for both beginners and seasoned growers seeking a hassle-free, superior growing experience. Its combination of efficiency, oxygenation, and low maintenance makes it a top choice for hydroponic enthusiasts looking for reliable, high-yield results.
