Root Spa 5 gal 4 Bucket System

The Active Aqua Root Spa 4 Bucket System is perfect for mid-sized scale grows, delivering deep water culture to growers who want more productivity without committing to a full-blown large setup. Each 5-gallon bucket is aerated independently with its own air stone, powered by a strong multi-outlet pump that maintains optimal oxygen levels at the root zone. Ideal for fast vegetative growth and dense, healthy root development with minimal effort. Installation is easy, maintenance is low, and it delivers top-tier performance. If you’re a hydroponic grower that wants to scale up with a proven, efficient system, this consistently reliable 4 Bucket System delivers solid results. This 4-bucket setup is a perfect middle ground between the compact Single-Bucket Root Spa System and Active Aqua’s 8-Bucket version — perfect for expanding without overcomplicating your grow space.
