Gardening with disposable pipette tip racks
Our first submission for the #Tips4Tips Sustainability Challenge comes from Jia Chen at Northwestern University who uses discarded pipette tip rack inserts in her gardens.
I use the pipette tip rack cover for the raised bed or climbing plant such as cucumber or bean to climb. And the rack it self can be used as container for credit card.
Fantastic!There's still plenty of time to submit you own #Tips4Tips for a chance to win $50.
