Alien Hydroponics RAIN System - 3 Pot 1 Row

Tired of inconsistent watering and nutrient imbalances holding back your plants? The Alien Hydroponics RAIN System solves this by perfectly mimicking natural rainfall, delivering a consistent and even feed every time. This innovative top-feed system is engineered for both beginner growers and experienced hobbyists, ensuring optimal nutrient absorption, enhanced oxygenation, and robust root health while minimizing waste. For those looking to scale their grow, larger configurations like the Alien Hydroponics RAIN System - 5 Pot 1 Row are available, while this 3-pot version offers a perfect balance for dedicated home setups.

Designed by Alien Hydroponics, this system's unique design prevents common issues like root rot, nutrient lockout, and salt buildup, making it compatible with a wide range of growing mediums. The glue-free, snap-on assembly makes setup and maintenance a breeze, regardless of your experience level. With options for 4-gallon or 8-gallon pots, you can customize the RAIN system to perfectly suit your space. If you are looking for a simplified automated feeding solution, you might also consider the Alien Hydroponics EasyFeed System - 2 Pot 1 Row Kit.

Please note: A nutrient reservoir/tank is required but not included. We recommend a tank with a minimum capacity of 30 gallons. GardenTank collapsible tanks are available, or you can supply your own.

FAQs

What kind of growing media can I use with the RAIN system?+

The RAIN system is highly versatile and can be used with various media types, including soil, coco coir, clay pebbles, and rockwool. Its top-feed design ensures even moisture distribution regardless of your chosen substrate.

Is this system difficult to set up?+

Not at all. The Alien RAIN system is designed for easy, tool-free assembly. It uses threaded fittings and snap-on pipes, so no glue is required. You can have it set up and running in a short amount of time.

What size nutrient tank do I need?+

The kit does not include a nutrient tank. For a 3-pot system, we recommend a reservoir with a minimum capacity of 30 gallons (120 liters) to ensure you have an adequate supply of nutrient solution for your plants.

Can I expand this system later?+

Absolutely. The RAIN system is fully modular and scalable. You can easily add more pots or reconfigure the layout to fit a larger space. For larger setups, check out the Alien Hydroponics RAIN System - 9 Pot 1 Row.

How is this different from an AERO or RDWC system?+

The RAIN system is a top-feed drip system. In contrast, an Alien Hydroponics AERO System - 24 Pot 3 Row mists roots directly, while an Alien Hydroponics RDWC - 12 Pot 3 Row submerges roots in oxygenated solution. Each method has unique benefits depending on your preference.
