Readers ask: What Is The Dependent Variable Of A Hydroponics?

So in this experiment, the independent variable would be the type of flower, and the dependent variable would be its rate of growth in a hydroponic environment.

What is the independent variable for hydroponics?

This is carried out by by measuring the length of the plant’s roots. 1. The independent variable in this science fair project is the method of cultivation – whether the plant is grown in soil, or hydroponically.. The dependent variable is the length of the plant’s roots after 3 weeks.

What is the hypothesis of hydroponics?

The hypothesis stated as follows “ If the hydroponic plants and plants grown in soil are given the same germinating and growing conditions, then the hydroponic plants will do as well if not even better than the plants grown in soil ” [3].

How is hydroponic productive?

Faster growing crops and plants As mentioned previously, plants grown hydroponically grow significantly faster than soil-grown plants. This is because the plant’s roots are literally bathing in nutrients, so they can easily and directly absorb them with minimal effort.

When were hydroponics invented?

In the late 1920s and early 1930s, Dr. William F. Gericke of the University of California extended his laboratory experiments and work on plant nutrition to practical crops growing outside for large scale commercial applications. In doing so he termed these Nutriculture systems “hydroponics”.

What are the disadvantages of hydroponics?
