No soil but it still grows in water (SMSnotes)

Another advantage is that many plants grow faster when raised hydroponically. In fact, some plants are ready for harvest 30 to 50 percent faster than they would be if they were grown in the soil. Plants need water for photosynthesis. Absorbed by the roots, water travels through a plant's stems to the chloroplasts in the leaves. Water also helps move nutrients from the soil into the plant. Too little water can cause a plant to wilt or droop. Plants need water for photosynthesis. Absorbed by the roots, water travels through a plant's stems to the chloroplasts in the leaves.
