The most common question new growers ask: do I need to spend ₹3,000–5,000 on LED grow lights to grow microgreens at home? The honest answer: probably not to start. Here's what light actually does — and when you genuinely need artificial lighting.
What Light Does for Microgreens
Microgreens don't need light for germination — they need darkness (the blackout stage). Light is only needed after germination, to trigger chlorophyll production and prevent the seedlings from stretching (going leggy). The good news: microgreens need much less light than fruiting plants like tomatoes or chillies.
Can I Use Natural Light?
Yes — if you have a south or east-facing window with 3–4 hours of indirect sunlight daily. That's enough for most varieties. Rotate the tray 180° every day for even growth.
What doesn't work: north-facing windows, deep interior spots with no direct sky view, or rooms where the only light comes from a bulb.
When You Actually Need Grow Lights
- Your home gets fewer than 2–3 hours of natural light daily
- Your microgreens keep growing leggy despite the right window
- You want to grow year-round in a windowless grow space
- You're scaling to commercial volumes where consistency matters
What to Buy If You Need One
A simple full-spectrum LED grow bar or panel in the 20–45W range is more than sufficient for home growing. Avoid expensive reef tank lights or specialist horticultural lights — they're overkill. Keep the light 6–10 inches above the canopy and run for 12–14 hours daily.
