RAIN System - 16 x 15L

The ALIEN ®️ RAIN ™ ️ system is a revolutionary automated irrigation system that reproduces rain. The system can be used with soil, coco or any other substrate of your choice and can be used as a recirculating or RTW (run to waste) system.

The RAIN  cap effectively delivers nutrients and air in the form of rain. This technique removes depleted residual nutrient salts and replaces them with fresh salts. The cover RAIN ™ cover the masks the light, thus preventing the formation of algae


The SILVER series features a heat reflecting silver polymer coating and more efficient pumps and ductwork than the BLACK series.

Patent-pending Dual-Flow ™ fittings are oversized by 50mm for a smoother system. These accessories are more than 3 times the internal size of 32mm. They allow water to pass through the slots on the sides of the accessory, allowing full drainage of the pot.

A 50mm heat reflective silver hose is used compared to the 32mm Black Series green 32mm.

The jars and lids are also made of heat reflective silver polymer.
