Who This Is For
- You are transitioning to an automated top-feed setup because manual watering leads to inconsistent growth across pots.
- You are scaling up to 28 pots because your smaller gravity system can no longer manage uniform nutrient delivery.
- You are installing a RAIN system because salt buildup in your current pots is stalling root development and yields.
What We Found
- The silver piping is more than just a look, it actually keeps the feed solution cool during long pump cycles.
- Those copper drain covers are the simplest way we have found to keep aggressive roots from clogging up the main lines.
- The lid design does a great job of keeping light out of the root zone while allowing for easy maintenance access.
What Users Say
- Users who switched to the RAIN system report more consistent plant heights because every pot gets the same feed volume.
- Growers running high-frequency fertigation say the raised drainage base stopped the root rot issues they previously had.
Alien Hydroponics RAIN System - 28 Pot 4 Row Kit
Nutrient distribution has always been challenging in large-scale plant systems, but that is now a thing of the past. If you have struggled with inconsistent growth rates or nutrient lockout, the Alien Hydroponics RAIN System - 28 Pot 4 Row Kit provides the professional-grade solution you need. By mimicking natural rainfall, this system ensures every plant in your 28-pot setup receives uniform hydration and oxygenation, driving massive yields and production consistency.
Engineered for commercial-level growers and researchers who demand precision, the RAIN Top-Feed system allows for maximum volume while minimizing wastage. Its unique design allows you to work with various growing mediums without the constant fear of root rot or salt buildup. Whether you are scaling up from a smaller setup or looking to upgrade to the 36 Pot 4 Row Kit, this system offers the flexibility and performance required for high-output environments.
Please note: This system requires a nutrient reservoir to operate. A tank is not included with the kit. We highly recommend the compatible Alien GardenTank 145 Gallon reservoir to complete your setup.

FAQs
The RAIN system is highly versatile and works exceptionally well with coco, clay pebbles, or soil-based mixes, thanks to its specialized drainage grid.
No, the RAIN system requires a separate reservoir to hold your nutrient solution. We recommend a GardenTank that matches the system's 145-gallon minimum capacity.
Alien Hydroponics generally recommends a watering frequency of one minute every hour, though this can be adjusted based on your specific environmental conditions and plant needs.
Yes, the modular design of the RAIN system allows for expansion up to 36 pots. You can also reconfigure the spacing between pots to fit larger plant footprints.
No. The system uses patent-pending threaded fittings and snap-on pipes, making it easy to assemble, maintain, and reconfigure without any tools or adhesives.
