I've been tasked with setting up a small-scale, automated hydroponic system for a community library's "living wall" educational exhibit, focusing on rare heirloom lettuces and herbs. My budget is tight at $800, and the space is a 10-foot by 6-foot interior wall with inconsistent, indirect natural light supplemented by basic LED shop lights. The real challenge is that the library requires the entire system, including the reservoir and nutrient dosing, to be concealed within a sound-dampened cabinet to maintain a quiet atmosphere, which severely limits airflow and complicates temperature control. I'm struggling to find a quiet, low-profile water pump and cooling solution that can fit within the enclosed space without causing humidity or noise issues, and I need to have a functional prototype ready for a board review in just under five weeks.
