Growing Chili Peppers Indoors Under Fluorescent Lights

Feasibility and Expectations

Indoor chili growing is rewarding but yields are modest (10–20% of outdoor). A 100W compact fluorescent (CFL) or two 4-foot T5 fixtures provide adequate light for a few plants.

Optimal Setup

• Light: 2× 54W T5 HO (4 bulbs total) or 200W+ LED panel. 14–16 hours/day.
• Temperature: 70–80°F day / 60–65°F night.
• Pollination: Hand-pollinate with brush daily during bloom.
• Container: 3–5 gallons, well-draining mix.
• Fertilizer: Balanced liquid at half strength weekly.

Harvest & Storage

Dry ripe red chilies whole—they store for years and "a little goes a long way." Fresh use is fine too.

Best Varieties for Indoors

Compact types: 'Thai Hot', 'Numex Twilight', 'Apache', 'Medusa'. Avoid large habaneros unless you have high-light setup.
