The "chemicals" are mineral nutrient salts – the same inorganic ions (like nitrate, potassium, calcium) that plants absorb from soil. They are not pesticides or synthetic hormones.
What's in it? The main mixes are N-P-K (Nitrogen, Phosphorus, Potassium) plus Calcium, Magnesium, and trace metals like Iron and Zinc.
Natural or Chemical? This is a philosophy debate, not a science one. The molecules are identical to what soil plants consume. However, they are derived from mineral salts, so it's not "organic" in the dirt-farming sense. You can get certified organic hydroponic nutrients, but they are less common.
Cost Comparison:
Startup Cost: Hydroponics is significantly more expensive. You need a system, pumps, nutrients, pH meters, etc.
Long-Term Cost: It can be more efficient. You save on water, fertilizer waste, and pesticides. Over time, the higher yields can offset the initial cost, but it's rarely "cheaper" than a simple backyard soil garden for a home grower.
