Alien Hydroponics RAIN System - 15 Pot 3 Row Kit
Inconsistent nutrient distribution and salt buildup have long been the enemies of successful hydroponic gardening, but the Alien Hydroponics RAIN System turns those challenges into a thing of the past. By mimicking natural rainfall, this kit ensures uniform hydration and oxygenation for every plant in your grow room, delivering the perfect balance of water and air directly to the root zone.
The RAIN Top-Feed 15 Pot 3 Row Kit is the ultimate solution for growers seeking a reliable, mid-sized system that supports steady outputs across different plant cycles. Unlike traditional RDWC systems, the RAIN system uses a specialized top-feed design that allows you to work with various growing mediums while eliminating the risk of root rot and nutrient lockout. This modular kit is designed for easy, glue-free assembly and can be scaled up to an Alien RAIN 36-pot system as your garden grows.
Please note: This kit requires a nutrient reservoir, which is not included. We highly recommend pairing it with a compatible tank like the Alien GardenTank 30 Gallon reservoir to complete your setup.
