Active Aqua Root Spa 8 Bucket Deep Water Culture System — 5 Gallon

Yes, the included professional-grade multi-output air pump is specifically designed to adequately oxygenate all eight 5-gallon buckets simultaneously. The pump provides sufficient airflow to maintain healthy dissolved oxygen levels in each bucket for optimal root health and growth. For those growing in warmer environments, pairing the system with an Active Aqua chiller can help maintain optimal reservoir temperatures and oxygen stability.

Each bucket has a 12.3-inch footprint. For optimal growing, allow 18-24 inches between bucket centers. A typical 4x8 foot grow space or two 4x4 tents can comfortably accommodate all eight buckets with adequate room for plant growth, airflow, and maintenance access.

Absolutely! Since each bucket operates independently, you can grow eight different plant varieties, each with customized nutrient strengths, pH levels, and feeding schedules. This flexibility is a major advantage over systems where all plants share one reservoir, like the Active Aqua Grow Flow.

While changing eight buckets takes more time than a single reservoir, most growers establish a routine: prepare nutrient solution in large batches (perhaps using an Active Aqua 55 Gallon Drum), change 4 buckets one day and 4 the next, or use a wet/dry vacuum to quickly remove and add solution. The trade-off is worth it for the independent control and disease isolation benefits.

This is where independent buckets shine—disease stays contained to one plant and won't spread through your entire system. Remove the affected plant, clean and sterilize that bucket, and the other seven plants continue growing unaffected. In recirculating DWC systems, root rot can quickly spread to all plants.

One multi-output pump is included and sufficient for all eight buckets. However, many serious growers keep a backup air pump on hand as insurance—if the air pump fails, all eight plants are affected simultaneously. A backup pump can save your entire crop in an emergency.

Yes, the 8-bucket system is ideal for small commercial operations, market gardening, or serious hobbyists. The independent bucket design allows for precise control and disease isolation, a valuable feature found across the Active Aqua lineup. Many commercial operations run multiple 8-bucket systems side by side for even larger production.

Each 8-inch basket holds approximately 2-3 gallons of growing medium depending on the type. For all eight buckets, plan on 16-24 gallons of clay pebbles, perlite, or your chosen medium. Buying in bulk (50-liter bags) is more economical for 8-bucket systems.
