Choosing High-Quality Hydroponic Supplies for Better Harvests

Hydroponics lets you grow anything from windowsill herbs to closet citrus trees. But success depends on quality supplies—especially nutrients.

Nutrients: The Critical Factor

Discount plant foods lack the trace elements hydroponic plants need. Beyond nitrogen, phosphorus, and potassium, hydroponics requires chlorine, calcium, boron, manganese, iron, sulfur, zinc, copper, magnesium, and molybdenum. Soil provides these naturally; hydroponic solutions must include them. Verify labels even at specialty stores.

Reservoirs: Opaque Is Essential

Transparent reservoirs grow algae, which kills plants. Use opaque containers—commercial or DIY—to block light.
