Active Aqua Root Spa 4 Bucket Deep Water Culture System — 5 Gallon

Ready to move up from a single 5-gallon DWC bucket without the complexity of large recirculating systems? The Active Aqua Root Spa 4-bucket system delivers the explosive growth of deep water culture hydroponics across four independent grow sites, perfect for growers seeking higher yields without added labor.

This four-bucket system is designed for growing multiple large plants while maintaining a cost-effective setup that optimizes plant growth. Unlike single-bucket systems, the multi-output air pump efficiently delivers oxygen-rich bubbles to all four buckets simultaneously, ensuring every plant receives the same vigorous aeration that drives accelerated root development.

The Root Spa promotes strong root development in each of the four 5-gallon buckets, thanks to the powerful multi-output air pump that delivers nutrients and oxygen efficiently to every grow site. Each bucket features a leak-proof design that ensures a clean, controlled growing environment. Compatible with various hydroponic growing mediums like clay pebbles, perlite, rockwool, or coco chips, you have complete flexibility to customize each plant's setup.

Everything arrives ready to assemble—no special tools required. Simply fill each bucket with nutrient solution, add your growing medium to the 8-inch baskets, connect the multi-output air pump, and you're ready to grow. Once the water starts bubbling in all four buckets, your deep water culture system is fully operational.

Media sold separately: You can use your choice of hydroponic media, such as clay pebbles, #4 perlite, rockwool mini cubes, coco chips, etc. Since this is a hydroponics system, soil should be avoided. Soil may contain dust, fungi, and bacteria, all of which can contaminate a hydroponics system.

NOTE: Setup of the multi-bucket Root Spa system is the same as that of the single-bucket system, with the main difference that the multi-bucket system uses a multi-output air pump, while the single-bucket Root Spa systems use a single dedicated air pump.

FAQs

Can I manage different nutrient levels for each bucket?+

Yes, since each bucket operates independently, you can maintain different nutrient strengths, pH levels, and even grow different plant varieties in each bucket. This is a major advantage over recirculating DWC systems where all plants share the same reservoir.

How powerful is the multi-output air pump?+

The included multi-output air pump is specifically sized to adequately oxygenate all four 5-gallon buckets simultaneously. Each bucket receives sufficient airflow to maintain healthy dissolved oxygen levels. For maximum performance, ensure the pump is positioned at or above bucket level to prevent back-siphoning.

Do I need to change water in all buckets at the same time?+

No, each bucket is independent, so you can change nutrient solution on different schedules if needed. However, for simplicity and consistency, most growers change all buckets on the same weekly or bi-weekly schedule.

What happens if the air pump fails?+

If the multi-output air pump fails, all four buckets will be affected simultaneously. We strongly recommend keeping a backup air pump on hand. Plant roots can begin to suffocate within hours without adequate aeration, potentially leading to root rot.

How much space do I need for the 4-bucket system?+

Each bucket has a 12.3-inch footprint. Allow 18-24 inches between bucket centers for adequate plant spacing and airflow. A 4x4 foot grow space can comfortably accommodate all four buckets with room for the air pump and maintenance access.

Can I expand this system to more than 4 buckets?+

The included air pump is designed for 4 buckets. To add more buckets, you would need to upgrade to a more powerful multi-output air pump or add a second pump. If you need more capacity out of the box, consider the Active Aqua Root Spa 8-site system.

What's the advantage over a recirculating DWC system?+

Individual buckets allow you to isolate problems—if one plant gets root rot or disease, it won't spread through the entire system. You can also grow different plant varieties with different nutrient requirements. The tradeoff is slightly more maintenance compared to single-reservoir recirculating DWC systems or other methods like automated ebb and flow systems.

How do I prevent algae in multiple buckets?+

Keep all buckets covered to block light, maintain reservoir temperatures between 65-72°F, change solutions regularly, and consider beneficial bacteria products. The opaque bucket design helps, but ensure basket lids fit snugly and no light penetrates through the growing medium.
