Their simplicity translates to lower maintenance, as there are no complex drip emitters or timers prone to clogging. Reduced Labor: Minimal weeding and no soil handling required.

Below the raft, the water is continuously aerated with air pumps and air stones, ensuring the roots have constant access to oxygen, which is critical for preventing root rot and promoting rapid growth. Holes are cut into the sheet to accommodate net pots, which are then filled with an inert substrate such as expanded clay pellets.
This design leverages the natural buoyancy of the water, creating a closed-loop environment where fish waste converts into plant food, and the plants, in turn, clean the water for the fish. A large, rigid sheet of food-grade High-Density Polyethylene (HDPE) floats on the surface of the sump tank.

Crops such as lettuce (Romaine, Butterhead, Oakleaf), Swiss chard, kale, basil, cilantro, and parsley perform exceptionally well. Heavier fruiting plants like tomatoes and cucumbers can be grown in raft systems, but they require significant structural support and larger root zones, making them better suited for media-filled grow beds.
