What kind of experiment can I do with hydroponics?

The possibilities are endless!  Here are just a few examples of questions to form a hypothesis about:

• Do plants grown hydroponically grow faster than those in soil?

• Does oxygenation of the water affect hydroponically grown plants?

• How does nutrient content affect plant growth?

• How does the pH of the nutrient solution affect plant growth?

• How does growth efficiency of hydroponics compare to growth efficiencey of soil grown plants?

What types of plants can I use for my experiment?

Anything can be grown hydroponically, but for an experiment, you will need to consider two things:

1. duration of experiment, and

2. the light that is available.

Some plants we suggest are basil, lettuce, herbs and flowers of all types.   The reason for this is that all of these plants will grow quickly, and they do not require the lighting that a fruiting plant (tomato, peppers, etc.) requires.
