Sometimes nature knows best. The revolutionary ALIEN® RAIN™ hydroponic system mimics rainfall to create a near-natural environment for the best possible plant growth. A fully automated watering system that replaces old nutrients with new and designed to help you grow the healthiest crops every time.

The RAIN™ system delivers nutrients evenly to your plants, just as rain would in nature. The patent-pending RAIN™ lid effectively delivers the nutrient solution in a rain-like effect and will wash away any salt residue. This enables the plants' roots to use all of the growing medium right up to the surface, for a healthy garden that will produce high yields.

RAIN™ also eliminates top-surface algae using light-mask technology and will allow the medium to dry uniformly between feeding. This function prevents nutrient lockout, enabling the optimum amount of nutrients and minerals to reach the plant without waste.

Fully adaptable, the RAIN™ system can be used with soil, coco or any other medium. With the ability to work as a recirculating or run to waste system, the RAIN™ system is highly adaptable and can be used to get the best out of any strain, giving you the power to grow how you want to.

What’s the difference between the “Black Series” and “PRO Silver Series”?


The patent pending Dual-Flow™ fittings are an oversized 50mm for a more free flowing system. These fittings are over 3x the internal size of the 32mm. They enable the water to pass through slots located on the sides of the fitting, allowing total drainage of the pot.

Heat-reflective silver 50mm pipe is used vs the Black Series green 32mm. 

The pots and lids are also produced from heat-reflective silver polymer.

The Silver Series feature copper plated drain covers which deter the roots from entering the pipework.
