Who This Is For
- You are upgrading to top-feed because your current manual watering creates inconsistent nutrient zones across the room.
- You are automating your irrigation because hand-watering 18 pots individually consumes too much of your daily labor.
What We Found
- The copper drain covers are the real deal for keeping roots from turning your drainage pipes into a solid mess.
- We love that the silver pipes reflect heat, which helps keep your nutrient solution from cooking during lights-on.
- The tool-free fittings make it easy to reposition the rows without needing a whole weekend to replumb the room.
What Users Say
- Growers who switched to this rain system say their plants look more vibrant thanks to the oxygenated rainfall effect.
- Users who moved from standard drip lines say they stopped seeing the salt crusting that used to cause root lockout.
Alien Hydroponics RAIN System - 18 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 18 Pot 3 Row Kit, you can say goodbye to inconsistent water and nutrient distribution forever. Designed for seasoned growers seeking a reliable, mid-sized solution, this system supports steady outputs and diverse plant cycles by mimicking natural rainfall to ensure optimal nutrient absorption, oxygenation, and root health while minimizing wastage.
The unique design of the RAIN Top-Feed System allows you to work with different growing mediums without worrying about root rot, nutrient lockout, or salt buildup. Whether you choose the 15-liter or 30-liter pot options, this kit is easy to assemble and maintain with its no-glue, tool-free design. For those considering other high-performance methods, you might also be interested in the Alien Hydroponics RDWC - 16 Pot 2 Row for deep water culture applications.
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 70 Gallon reservoir to complete your setup.

FAQs
What growing mediums are compatible with the RAIN system?
The RAIN Top-Feed system is highly versatile and can be used with soil, coco coir, or mixed substrates, making it ideal for growers who want the benefits of automation without switching to pure hydroponics.
Do I need to buy a separate reservoir?
Yes, the RAIN system requires a nutrient reservoir to function. We recommend a minimum capacity of 70 gallons (280 liters) for the 18-pot kit. You can use an Alien GardenTank or your own reservoir.
How does the system prevent salt buildup?
The system mimics natural rainfall, which helps wash away residual salts from the medium. The raised drainage grid and sloped base ensure these salts are flushed out efficiently to prevent lockout.
Can this system be used on uneven ground?
Yes, unlike RDWC systems which require a perfectly level surface to maintain water levels, the RAIN Top-Feed system is much more forgiving and can be used on slightly uneven surfaces.
What is the recommended watering frequency?
Alien Hydroponics generally recommends a watering frequency of one minute every hour, though this can be adjusted using the included cycle timer based on your plants' specific needs and growth stage.
