- You are upgrading to a top-feed system because your existing setup struggles to distribute nutrients evenly across your 20-pot array.
- You are switching to an automated top-feed architecture because you want to use diverse growing mediums while preventing nutrient lockout.
- The copper-plated covers are a smart addition because they naturally deter roots from clogging the pipe network.
- The no-glue, tool-free design means you can easily reconfigure the system or expand your facility without a headache.
- Growers who switched to the RAIN system say they stopped worrying about localized saturation because the delivery remains uniform.
- Operators who adopted the copper drain covers report that they no longer spend time clearing obstructed pipes during the cycle.
Alien Hydroponics RAIN System - 20 Pot 4 Row Kit
Nutrient distribution has historically been the Achilles' heel of contained plant systems, but the Alien Hydroponics RAIN System turns that challenge into a competitive advantage. By mimicking the gentle, uniform delivery of natural rainfall, this automated top-feed system ensures that every plant in your 20-pot array receives optimal oxygenation and nutrient absorption without the risks of localized saturation.
Designed for high-capacity professional operations and collaborative grows, the RAIN 20 Pot 4 Row Kit offers the scalability of an industrial system with the precision of a boutique setup. While traditional RDWC systems are excellent for deep water culture, the RAIN system’s unique top-feed architecture allows you to utilize various growing mediums while effectively washing away residual salts and preventing nutrient lockout. The no-glue, tool-free design ensures that whether you are setting up a new facility or expanding an existing one, maintenance remains simple and efficient.
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 can I use with the RAIN system?
The RAIN system is highly versatile and can be used with soil, coco coir, or expanded clay pebbles. Its top-feed design ensures even distribution regardless of the medium.
Is a nutrient reservoir included in the kit?
No, a reservoir is not included. You will need a tank with a minimum capacity of 145 gallons (550L). We recommend the Alien Hydroponics GardenTank series.
How often should I set the timer to feed my plants?
Alien Hydroponics typically recommends a watering frequency of one minute every hour, though this can be adjusted based on your specific plant needs and environment.
How does the RAIN system prevent root rot?
The system uses a sloped base and raised drainage grid to ensure water never pools at the bottom of the pot, while the top-feed delivery ensures high levels of oxygen reach the root zone.
How do I maintain the system between cycles?
We recommend flushing the system with clean water and a disinfectant like ROOT ROT X™. The no-glue design allows you to easily take apart pipes for deep cleaning if necessary.
