Buy or make a hydroponic system with clean containers, pumps, reservoirs, growing media (perlite, rockwool, or clay pellets), and lighting (if growing indoors).
Plants need proper lighting. LED grow lights are common in indoor hydroponics. Adjust light spectrums and durations for different plants.
Use balanced hydroponic fertilizer solutions designed for plant growth. Follow instructions to mix and change nutritional solutions.
Regularly check and maintain nutrition solution pH and EC. Most plants like 5.5–6.5 pH. EC levels indicate solution nutrient concentration.
Keep your hydroponic system clean to avoid algae, germs, and fungi. Sterile equipment and water change periodically to minimize nutrient imbalances and infections.
Oxygenate and circulate the nutritional solution. Oxygenation stimulates root growth and prevents asphyxia. Pumps or air stones can oxygenate the solution.
Keep plants and fertilizer solution at appropriate temperatures. Most plants require 65-75°F (18-24°C). Avoid temperature extremes.
Know your plants' demands. Different plants need different nutrients, pH, and growing conditions. Change your hydroponic system.
