It’s amazing to open a pack of seeds and see, well, just seeds. It’s not until you harvest and process seeds for the first time that you truly appreciate just how difficult it can be to separate the seed from all the chaff and waste material.
Our first seed collection effort in the flagship Edible Learning Lab brought that truth to light. We experimented with a few techniques using screens and a little forced air from a fan to determine the best process.
But what works for one type of seed may not work for another. Some seeds are heavier and others are barely discernible to the naked eye. What we did discover was just how fun the discovery process was. Our students would try a technique that was successful with another variety and adjust as needed. In the end, we figured out what worked and what didn’t and screens were a very handy tool.
Design and build a series of screens that can be used to harvest and process seeds from the varieties that you grow in the Lab. Use screen material of different sizes and patterns to make them as versatile as possible.
