Active Aqua Grow Flow 2.0 Expansion Kit Hydroponic Grow System — 5 Gallon

Yes, this expansion kit requires a Grow Flow control unit and reservoir, which are sold separately. The expansion kit integrates seamlessly with your existing Grow Flow system to add six additional plant sites.

You can expand your Grow Flow system up to 48 total plant sites by adding multiple expansion kits. Each kit adds six plant sites, so you can scale your operation based on your space and growing needs.

Each bucket is designed to hold approximately 13 liters of clay pebbles (hydroton), but you can also use other hydroponic growing media such as perlite or coco coir. To ensure your nutrient solution stays at the perfect temperature, we recommend using an Active Aqua chiller.

Yes, the Grow Flow 2.0 Expansion Kit is compatible with all standard ebb and flow controllers, not just Active Aqua controllers. The system uses standard 3/4" tubing connections that integrate with most hydroponic flood and drain systems.

Each bucket features a built-in overflow mechanism that prevents water from spilling over the bucket rim if the drain becomes clogged or the fill cycle runs too long. This protects your plants, equipment, and grow area from water damage.

The centered drain design minimizes standing water at the bottom of each bucket, which reduces the risk of root rot. This design promotes better oxygen circulation around the root zone for healthier plant growth, a key benefit for this style of hydroponics versus deep water culture systems.

Yes, the expansion kit includes everything you need for installation: 6 outer buckets, 6 inner buckets, 6 tee connectors, 3 elbow connectors, 6 screen fittings, 12 rubber washers, and a 25-foot roll of 3/4" tubing.

Each bucket measures 12 x 8.5 x 11.75 inches with a 10.75-inch inside diameter. Plan for adequate spacing between buckets to allow for plant growth and airflow. A typical arrangement might require approximately 6-8 square feet for all six buckets.
