Book 3 in the Tech Explorers League series

It’s the start of the end-of-year holidays, but Dembe is already bored. His friends are bored. Even their robot companion, Tenba, is bored. So what are they going to do?

But before they know it, the Tech Explorers are part of a string of incidents and disasters that threaten to destroy the holiday season for the entire community.

In true Tech Explorers League fashion, the kids refuse to give up. They come up with a plan that somehow involves growing plants without soil using a technique called hydroponics!

Can the kids work through their doubt and fears? Will there be enough food to go around? Will the kids be able to help save the holiday season? Join the kids and find out as they tackle the problem with technology, even in something as traditional as farming!

For Grades 4-9 or ages 9 to 14. (Includes illustrations)
