Who This Is For
- You are upgrading to a 27-pot layout because hand-watering containers at this scale leads to uneven nutrient dosing.
- You are switching to a top-feed rain system because you want the benefits of hydroponics without the root rot risks.
What We Found
- Those RAIN lids block light from hitting the medium, which stops surface algae growth before it can even start.
- We like the copper drain covers because they actually work to turn roots away from the plumbing without chemicals.
- The tool-free assembly is a huge time saver when setting up a room this large for the first time.
What Users Say
- Operators who switched to this 27-pot layout say they stopped seeing the nutrient lockout common in hand-fed rooms.
- Growers using the rainfall mimicry found that their plants drink more because the roots get oxygen with every feed.
- Users report that the dual-flow fittings keep the system running smoothly even as the root mass gets aggressive.
Alien Hydroponics RAIN System - 27 Pot 3 Row Kit
Nutrient distribution has always been challenging in contained plant systems, but that's a thing of the past. With the Alien Hydroponics RAIN Top-Feed System 27 Pot 3 Row Kit, you can say goodbye to inconsistent water and nutrient distribution. Designed for professional-level operations that require efficient, high-capacity systems, this kit mimics natural rainfall to ensure optimal nutrient absorption, oxygenation, and root health while minimizing wastage. For those requiring a smaller footprint, the Alien Hydroponics RAIN System - 12 Pot 2 Row Kit offers the same top-feed efficiency, while growers looking for maximum oxygenation might prefer an Alien Hydroponics RDWC - 21 Pot 3 Row system.
The unique design of the RAIN Top-Feed System allows you to work with different growing mediums while eliminating worries about root rot, nutrient lockout, and salt buildup. With options for 8-gallon/30-liter and 4-gallon/15-liter pots, growers can customize the RAIN System to fit their specific preferences. With no special tools and a no-glue design, this kit is easy to assemble and maintain, regardless of your gardening experience.
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.
