Hello and welcome,
this model is designed to float on water and to provide optimal water delivery for up to 4 ultrasonic foggers (16/20mm ceramic piezeo). This can be used in a fogponic setup to grow e.g. different types of lettuce.
(Parts: 2 Ultrasonic fogger driver boards, 4 piezeo elements and 4 foam straws)

Assembly:
2. Test fit the piezeo elements. Make sure that they fit in the socket and have light contact with the foam staws. The contact to the foam staw is important for high amounts of fog.
3. Add wiring and make it waterproof(ish) with shrink tubes.
4. Add cover and M4 bolts.
5. Connect wires to driver board. Place floater in water and let the foam staws pull water for about 10 minutes. Power the driver board and adjust the foam staws, so that a lot of fog is produced.
(6. Add deflectors to reflect the fog stream and to create a vortex)
