Alien Hydroponics RAIN System - 36 Pot 4 Row Kit

Nutrient distribution has traditionally been the biggest bottleneck in large-scale hydroponic systems, often leading to inconsistent growth and wasted resources. The Alien Hydroponics RAIN System - 36 Pot 4 Row Kit eliminates these challenges by providing a professional-grade solution for commercial growers and researchers who demand precision. By mimicking the delivery of natural rainfall, this system ensures every plant receives uniform nutrient absorption and maximum oxygenation. Whether you are expanding your facility or comparing this to an Alien RDWC system, the RAIN kit delivers the production consistency required for high-yield harvests.

Designed for versatility, the RAIN Top-Feed System is compatible with various growing mediums while proactively preventing common issues like root rot, nutrient lockout, and salt buildup. Available in both 4-gallon (15L) and 8-gallon (30L) pot configurations, this kit allows for complete customization to fit your specific canopy requirements. Its tool-free, no-glue assembly ensures that even a massive 36-pot installation remains straightforward to set up and maintain.

Please note: The RAIN system requires a nutrient reservoir or tank to function, which is not included. We recommend the GardenTank collapsible tanks for a seamless integration.

FAQs

What makes the RAIN system different from standard drip systems?+

Unlike standard drip lines that can clog or deliver uneven pressure, the RAIN system uses a specialized lid and distribution manifold that mimics natural rainfall, ensuring the entire root zone is hydrated evenly while oxygenating the solution.

Can I use organic nutrients in this system?+

While the RAIN system is highly efficient, we recommend using mineral-based nutrients to ensure the longest lifespan of the pumps and to minimize maintenance. If using organics, regular cleaning of the filters and lines is essential.

Is a reservoir included in the 36-pot kit?+

No, a nutrient reservoir is not included. For a system of this size, we recommend a tank with at least 145 gallons (550 liters) of capacity, such as the Alien GardenTank.

What is the purpose of the copper-plated drain cover?+

Copper is a natural root deterrent. By plating the drain covers in copper, the system prevents aggressive root systems from growing into and clogging the drainage pipes, maintaining a free-flowing system.

Can this system be used with soil or coco coir?+

Yes, the RAIN system is highly versatile and works exceptionally well with coco coir, soil, or mixed mediums, making it a great choice for growers who prefer traditional substrates over pure water culture.
