Alien Hydroponics: RAIN
The ALIEN RAIN Hydroponic System recreates natural rainfall to deliver healthier, more consistent plant growth across a wide range of growing media. This flexible, modular, and scalable system is fully automated, evenly distributing nutrients across the surface of the medium to maximize root development and prevent salt buildup. Light-masking technology eliminates top-surface algae, while integrated air channels promote optimal oxygen flow and uniform drying between feedings to prevent root rot and nutrient lockout. Compatible with soil, coco, rockwool, clay pellets, and more, the RAIN system supports both recirculating and drain-to-waste setups, giving growers complete control to achieve optimal results with any strain.
Please note: RAIN requires a nutrient reservoir / tank to hold the nutrients or water, but a tank is not included with the kit. GardenTank collapsible tanks are available, or you can supply your own.
