About Us

Cangro is a proudly South African initiative that’s activated over 20,000 learners across more than 100 schools, spanning 4 provinces and 2 continents — and we’re still growing!

The Upside-Down Tomato Challenge flips the script: just because life feels upside down doesn’t mean you can’t thrive. Over 8 weeks, kids and adults grow tomatoes from the bottom of repurposed cans, transforming everyday obstacles into something vibrant and full of life.

In partnership with The Chaeli Campaign, the challenge champions inclusion, with sponsored entries for disabled and disadvantaged learners. Weekly experiments, hands-on activities, and fun mini competitions teach sustainability in a way that’s memorable, practical and joyful.

Businesses also get in on the fun — Individuals & teams compete to grow the biggest upside-down tomato plant while supporting inclusive education. Planting days at sponsored schools spark connection and community, proving that when everyone grows, everyone wins.
