What this video covers

The crew of the vessel *Panda Moussaillon* transitions from sailing to land-based aquaponics, constructing a "sabloponie" (sand-ponics) system in a greenhouse. The setup utilizes four 15-meter tables filled with 26 tons of siliceous sand, which acts as a biological filter and growth medium for strawberries and vegetables.▶ 5:32 The system operates on a tide-based irrigation cycle, where water from fish tanks is pumped into the sand beds and siphoned out automatically to ensure root aeration.▶ 4:32 The construction involves a three-layer base: a bottom layer of volcanic pozzolana for drainage, a geotextile separator, and a top layer of washed, non-calcareous siliceous sand.▶ 11:44 To maximize plant vigor, the crew manually removes early flowers and small fruit from young strawberry plants to encourage root development.▶ 15:10 The project concludes with the rebranding of the channel from "Au grès des voiles" to "Aquaferme," reflecting a permanent shift toward sustainable land-based food production systems.▶ 24:12
