Who This Is For
- You are switching to rain-style lids because your current drippers clog too often and cause uneven nutrient delivery.
- You are scaling up your row count because hand-watering individual pots has become a full-time job you cannot sustain.
What We Found
- The silver piping actually deflects enough light to keep your nutrient temps stable without a dedicated chiller.
- We found the copper-plated drain covers are a simple fix that finally stops roots from choking the main return line.
What Users Say
- Growers moving from RDWC say they stopped worrying about root rot because roots are no longer sitting in water.
- Users who set this up alone report the snap-together fittings saved them a full day of plumbing and gluing.
Alien Hydroponics RAIN System - 8 Pot 4 Row Kit
Nutrient distribution has always been a challenge in contained plant systems, but that's a thing of the past. With the Alien Hydroponics RAIN Top-Feed System 8 Pot 4 Row Kit, you can finally say goodbye to inconsistent water and nutrient distribution. Ideal for growers looking to scale beyond hobby levels, this system provides professional yields and flexibility without the complexities of industrial-scale setups. Unlike traditional RDWC systems, the RAIN technology mimics natural rainfall to ensure optimal nutrient absorption, oxygenation, and root health while minimizing waste.
The unique design of the RAIN Top-Feed System allows you to work with various growing mediums without the fear of root rot, nutrient lockout, or salt buildup. Whether you prefer 4-gallon (15L) or 8-gallon (30L) pots, this kit is fully customizable to your environment. Designed for simplicity, the no-glue, tool-free assembly makes it accessible for both novice and expert gardeners.
Please note: This kit requires a nutrient reservoir, which is not included. We highly recommend pairing it with a compatible tank like the Alien GardenTank 30 Gallon reservoir to complete your setup.

FAQs
Does this kit include a nutrient reservoir?
No, the RAIN system requires an external nutrient reservoir or tank to hold water and nutrients. We recommend using an Alien GardenTank or a similar high-quality reservoir with at least a 30-gallon capacity.
What growing mediums can I use with the RAIN system?
The RAIN system is highly versatile and works exceptionally well with coco coir, clay pebbles, or soil. Its top-feed design ensures even saturation regardless of the medium chosen.
How often should I water my plants in this system?
Alien Hydroponics typically recommends a watering frequency of one minute every hour during the lights-on cycle, though this can be adjusted based on your plants' specific needs and growth stage.
Is the system difficult to assemble?
Not at all. The system features a glue-free design with threaded fittings and snap-on pipes. No special tools are required, and the included instructions guide you through the process step-by-step.
How do the copper-plated drain covers help?
Copper is naturally repellent to plant roots. By plating the drain covers in copper, the system prevents roots from growing into the pipe network, which avoids clogs and ensures consistent drainage throughout the cycle.
