Who This Is For
- You are switching to automated top-feeding because hand-watering 20 pots consistently takes too much time.
- You are moving to a rainfall delivery system because standard drip lines create salt pockets and nutrient lockout.
- You are choosing a tool-free layout because glued pipe networks make deep cleaning between cycles a massive chore.
What We Found
- The copper-plated drain covers are a simple fix for the constant root intrusion we see in other top-feed systems.
- Those silver pipes actually keep the solution cooler in hot rooms compared to standard black or green tubing.
- The tool-free fittings are great because they make it much easier to deep clean the plumbing between cycles.
What Users Say
- Growers tell us the rain lids provide such even saturation they stopped seeing dry pockets in their larger pots.
- Teams running multi-row setups say the automated cycles let them focus on pruning instead of manual fertigation.
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.

Support & Manuals

FAQs
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.
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.
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.
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.
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.
