Hydrostacks - Rutgers engineering students design, optimize, and automate duckweed growing modules.
From top-left clockwise: Angela Yao, Merve Pekdemir, Ryan Volpi, and Stefan Luong.
For their senior design project, these students tackled some of the difficult problems faced when growing duckweed in vertically stacked trays.
The team developed a lighting system using acrylic trays stacked only a few inches apart. The acrylic conducted and spread the LED light evenly throughout the system.
Manipulation of water levels and density sensors allowed for automation of the duckweed harvesting.
Temperature and pH sensors monitored the health of the duckweed..
