How much growth will a lucky bamboo grow in a month?

Question

My son is doing a science project and testing to see if a plant grows better in soil or water. I was thinking Lucky Bamboo would work since it can grow in either water or soil. My problem is he only has a month to do this project, so I was wondering how much growth he will see in a month. Or is there a different type of plant that will work better? It will be done inside since it is winter. We live in South Carolina, and lately it has been getting in the 20’s and 30’s.

Answer 1

An interesting project. With only a month to study the plants, I’m thinking he might see more happening with cuttings from an herb plant, possibly some mint. Make sure that the two test plants are in the same location, and that the one in soil gets enough water to keep it healthy, but not too much, because overly wet soil inhibits the root growth.
