Alien Hydroponics RAIN System - 4 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 Hydroponics RAIN Top-Feed System 4 Pot 4 Row Kit, you can say goodbye to inconsistent water and nutrient distribution forever. Designed for both beginners and experienced hobbyists, this system mimics natural rainfall to ensure optimal nutrient absorption, superior oxygenation, and peak root health while minimizing wastage. For growers interested in deep water culture, we also offer the Alien Hydroponics RDWC - 4 Pot 2 Row.

The unique design of the RAIN system allows you to work with different growing mediums without worrying about root rot, nutrient lockout, or salt buildup. With options for 15-liter or 30-liter pots, you can customize your footprint to match your space. The no-glue, tool-free design ensures that assembly and maintenance are straightforward and stress-free.

Please note: The RAIN system requires a nutrient reservoir or tank to hold the water/nutrients, which is not included. We recommend using a GardenTank collapsible reservoir for the best compatibility.

FAQs

How does the RAIN system mimic natural rainfall?+

The RAIN system utilizes a top-feed delivery method that drips nutrient solution evenly over the growing medium, simulating the gentle and uniform distribution of natural rain.

Can I use this system with soil or coco?+

Yes! One of the biggest advantages of the RAIN system is its versatility. It is compatible with soil, coco, or other hydroponic mediums, making it perfect for various growing styles.

Do I need to buy a separate reservoir?+

Yes, the RAIN system requires a nutrient reservoir to function, which is not included in the kit. We recommend a tank with at least 30-gallon capacity for this 4-pot kit.

Is the system difficult to assemble?+

Not at all. The Alien Hydroponics RAIN system features a no-glue design with threaded fittings and snap-on pipes, allowing for quick assembly without specialized tools.

How often should I water my plants?+

Alien Hydroponics generally recommends a watering frequency of one minute every hour, though this can be adjusted based on your specific plants and environment using the included cycle timer.
