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.
