|MadSci Network: Botany|
I am doing a project on a modified hydroponics system. My plants are in glass bowls and light enters freely. In the control and my first variable, there is no air space for the roots. However, the third plant has air contact with its roots. These plants do not seem to be doing as well as the same type grown in soil. As the nutrient mix contains everything necessary to the plant, the difference must be due to the ability of light to penetrate to the roots.
Re: Why is direct sunlight to roots inhibitory to plant growth?
