In this day and age we are all much more aware of the importance of protecting our environment. What many do not know is that growing hydroponically is far better for the environment than traditional growing methods; You have the choice of recycling the water you drain, instead of leaching fertilizer into the ground.
Starting with a pathogen-free product, you have less disease problems and thus use far less pesticides (90% less). Fertilizer is used only in half strength and overall a commercial grower uses only 25% of the amount of fertilizer normally required for the same crop grown in soil.
