This week Aled, Ben, and Chris are trapped in a Botanical Greenhouse.
Are they smarter than a primate?
Can they figure out the mysteries of the marigold?
Will their maths let them down…?
Tune in to listen to them weeding out the duckweed from the clues!
We're also on the Instagrams with the rest of the kids and we still have no idea how it works.
