Material List and Cost Calculator for Building a Wash Table and Aerator
Robert Hadad, Extension Vegetable Specialist
Cornell Vegetable Program
Our model wash table was built from parts purchased entirely from a decently stocked hardware store. The list contains all the components we used to build the main table, the side modular tables, and the "dirty table". Also listed are the prices we paid to give you an idea of a building price. The real goal for these tables is to demonstrate that it doesn't require high priced equipment to get started in setting up an easily cleanable wash line set-up. The idea is to have something usable whether it is indoors or outside under canopies. The key is having the tables and equipment that can be easily cleaned and sanitized while being low-cost, easy to build, and totally functional.
There is a second page of the spreadsheet that includes the materials list and cost for building an aerator. The concept of the aerator is to pump air in a tank of water that can agitate leafy greens or heads of lettuce, escarole, etc. to quickly remove soil and debris as well as keeping any added sanitizer in the water to reach in around the produce. The Jacuzzi motor was found at a spa parts website. I ordered a 1 hp model. Very quickly we realized that this was too powerful for any tank or basin less than 50 gallons or greater and needs high sides. A 7/8 hp motor or something smaller would work fine. The motor purchased had a 2" diameter exhaust that fit easily to a 2" PVC pipe. Do not glue the PVC pieces in the bottom of the tank together totally. The unit will suck in soil and debris when you turn off the motor after use and will need cleaning after each day's use. Having the PVC pipes in the bottom of the tank fit snuggly with the inside perimeter will help in keeping the unit from floating when the motor is turned on. More holes drilled into the PVC would help reduce floating. Using an easily cleanable weighted object to hold down the pipes can also work. To see the aerator in action, go to our video and the last couple of minutes of the video is on the aerator.

African Eggplant Participatory Breeding Kick-Off
March 5, 2026
Join us to learn about the Cornell African Eggplant Research Project and learn how you can participate! African eggplant, also known as Bitterball, Garden Egg, Kittley and other names, is an important crop for many members of our community with heritage from regions such as sub-Saharan Africa, Southeast Asia, and Brazil. Since 2024, the Cornell African Eggplant Research Project has been collaborating with growers and community partners across New York to develop high-quality varieties adapted to the Northeast U.S. In this meeting, we will share information about growing and preparing African eggplant, highlight our research to date, and invite partners to collaborate with us in our 2026 participatory breeding and variety selection efforts.

Managing the Invasive Swede Midge Webinar
March 6, 2026
Swede midge is an invasive fly that causes serious economic losses to brassica crops. Due to its small size and hidden feeding habits, swede midge is often called an "invisible pest" and damage may be misdiagnosed. In this webinar, we will review the swede midge life cycle and crop damage symptoms, current management recommendations, new research findings, and highlights from on-farm case studies with a focus on organic management.
