DIY Hydroponics: Grow Food Indoors Without the Price Tag

Commercial hydroponic systems cost hundreds. A DIY deep-water culture or NFT setup costs $50–$100 in hardware-store parts and yields faster, cleaner harvests than soil—year-round, in a closet or basement.

Why Hydroponics Wins

• 90% less water (recirculated).
• No soil-borne pests/diseases.
• Precise nutrient control = 30–50% faster growth.
• Vertical stacking multiplies yield per square foot.

Start Simple: Kratky Method (Passive, No Pump)

5-gallon bucket, net pot, clay pebbles, hydroponic nutrients, lettuce/herb seedling. Roots suspend in nutrient solution; air gap provides oxygen. Zero electricity.

Scale Up: DWC or NFT

Add air pump ($15), timer, PVC channels. Automate lighting with full-spectrum LEDs. Monitor pH (5.5–6.5) and EC weekly.
