Herbs are the most forgiving plants you can grow indoors — but only if you nail the light. A sunny windowsill alone almost never cuts it past late October. Here are the grow lights we trust for indoor herbs in every budget and space.
1. Barrina T5 Strip Lights (6-pack, $59) — Best for shelves
If you have a shelf of pots or seed trays, nothing beats linkable T5 strips. Almost no heat, simple plug-and-play, and one pack covers a full 4-foot shelf.
2. Spider Farmer SF-1000 ($139) — Best all-around
Samsung LM301B diodes, dimmable driver, and a real 3-year warranty. Overkill for a single basil plant, perfect for a 2x2 foot herb garden.
3. Soltech Aspect Pro ($299) — Best for living rooms
A pendant-style fixture that genuinely looks like a designer light. Warm-white spectrum keeps your dining room from feeling like a greenhouse.
4. GE Grow Light LED Bulb ($19) — Best single-bulb
Screws into any standard E26 socket. Stick it in an existing desk lamp, point it at a pot, and your basil will be measurably happier.
How much light do herbs actually need?
Most leafy herbs want a Daily Light Integral (DLI) of 12–18 mol/m²/day. In plain English: 14–16 hours per day under a decent LED, kept 6–12 inches above the canopy.
Common light mistakes
- Light too far away — herbs stretch and flop.
- Spectrum too blue — leaves stay tiny.
- Running 24/7 — plants need a dark period to rest.
Frequently asked questions
Can I grow herbs in a north-facing window without a light?
Almost never — natural light alone produces leggy, low-yield plants outside the peak summer months.
Are LED grow lights safe for pets?
Yes. They're cool to the touch and emit no UV worth worrying about, but keep wires out of cat reach.
