From Killeen, Texas: Central Texas College Horticulture students are gaining hands-on experience with a method of growing plants without soil, known as hydroponics. This technique involves planting in a hydroponic planter, where students can learn by doing. As part of their training, the students planted lettuce and examined leaves to identify plant species.

Further details about the hydroponics method and the students' experience are available from the source. The method allows plants to grow without the use of soil, instead using alternative means to support plant growth.

The students' hands-on experience with hydroponics is providing them with a unique learning opportunity, allowing them to explore the possibilities of soilless plant growth.
