Who This Is For
- You are moving to a top-feed system because inconsistent nutrient distribution in your pots is slowing down growth.
- You are upgrading your drainage setup because standing water in your current pots is leading to root rot and lockout.
- You are switching to the RAIN system because hand-watering twelve large pots every day is becoming a massive labor drain.
What We Found
- Those copper-plated drain covers are a lifesaver if you have ever had to snake a root-clogged 50mm pipe.
- We noticed the silver piping stays noticeably cooler under intense lights compared to standard black tubing.
- The Rain Brain controller is surprisingly intuitive for managing delivery cycles without needing a separate timer.
What Users Say
- Users who moved from glue-together systems say the tool-free assembly saved them a full day of setup labor.
- Growers who switch between coco and pebbles say they no longer worry about nutrient lockout when changing mediums.
Alien Hydroponics RAIN System - 12 Pot 4 Row Kit
Nutrient distribution has always been challenging in contained plant systems, but that's a thing of the past. With the ALIEN RAIN Top-Feed System 12 Pot 4 Row Kit, you can say goodbye to inconsistent water and nutrient distribution. Designed for seasoned growers wanting a reliable, mid-sized system that supports steady outputs and different plant cycles, the RAIN Top-Feed 12 Pot 4 Row Kit mimics natural rainfall to ensure optimal nutrient absorption, oxygenation, and root health, while minimizing wastage. While this drip system is highly efficient, those looking for deep water culture solutions might also consider the Alien Hydroponics RDWC - 12 Pot 2 Row for different growth characteristics.
The unique design of the Rain Top-Feed System allows you to work with different growing mediums while not worrying 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 as they deem fit their preferences. With no special tools and a no-glue design, this kit is easy to assemble and maintain, regardless of experience in gardening.
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
How does the RAIN system mimic natural rainfall?
The system uses a top-feed delivery mechanism that distributes water and nutrients evenly over the growing medium, simulating the way rain naturally saturates soil, which promotes better oxygenation and nutrient uptake.
What growing mediums are compatible with this system?
The RAIN system is highly versatile and can be used with various mediums, including coco coir, soil, or mixed substrates, thanks to its efficient drainage and top-feeding design.
Is a nutrient reservoir included in the kit?
No, a nutrient tank is not included. We recommend a reservoir with at least a 70-gallon (280L) capacity, such as the GardenTank collapsible series.
How often should I set the watering frequency?
Alien Hydroponics typically recommends a watering frequency of one minute every hour, though this can be adjusted based on your specific plant needs and environmental conditions.
Does the system prevent root rot?
Yes, the combination of the raised drainage grid, sloped pot base, and copper-plated drain covers ensures that water does not stagnate and roots stay clear of the plumbing, significantly reducing the risk of root rot.
