Herbs are the best starting point for indoor growing — they’re fast, forgiving, and genuinely useful in the kitchen. The one thing they need that most windowsills can’t reliably provide: consistent, strong light.
The good news is you don’t need to spend much to solve that problem. There are solid LED grow lights under $100 that will keep basil, mint, parsley, cilantro, and chives producing all year. The bad news is the category is flooded with garbage, and the marketing specs often lie.
Here’s what actually works, what to skip, and why.

What Herbs Actually Need from a Grow Light
Before buying anything, understand what you’re buying for. Herbs are medium-light plants — they need more than a dark corner but less than fruiting vegetables like tomatoes.
Practical targets for herbs:
- Light intensity: 200–400 PPFD (micromoles per square meter per second) at plant level
- Daily light integral: 12–16 hours of light per day
- Spectrum: Full-spectrum or blue-white light (6000–6500K) keeps herbs compact and leafy
If those terms are unfamiliar, check out our Grow Light Buying Guide for Beginners — it explains everything in plain English.
The short version: most budget LEDs will work fine for herbs if you hang them at the right height and run them long enough. The difference between a $30 light and a $70 light shows up in efficiency and lifespan, not necessarily in whether basil grows.
VIPARSPECTRA P600
Best overall for a small herb shelf
The VIPARSPECTRA P600 is a panel-style full-spectrum LED that punches well above its price. VIPARSPECTRA has been in the grow light market for years and the P600 reflects that experience — the diodes are better quality than what you get from no-name Amazon lights at this price.
Coverage: 2×2 ft veg, 1.5×1.5 ft if you want maximum output. For herbs, run it at 18–24 inches above your plants and you’ll cover a solid group of 3–5 herb pots.
What I like about it: The daisy-chain feature lets you link multiple units together and run them on the same timer — useful if you’ve got a longer shelf. The build quality feels solid, and the fan is quiet enough that it won’t bother you in a living space.
What to know: It draws about 100W at the wall. That’s real power consumption — not the inflated “equivalent” wattage that most cheap lights advertise. For herbs on a 16-hour schedule, that’s about $4–6/month in electricity at average US rates.
Verdict for herbs: Great choice if you have a 2×2 space and want a light you won’t need to replace in six months.

SPIDER FARMER SF-300
Best for a dedicated small herb setup or grow tent
Spider Farmer makes some of the most respected budget-to-mid-range grow lights available, and the SF-300 is their smallest panel. It uses Samsung LM301 diodes — the same diode brand used in lights that cost 4–5x as much — paired with a Meanwell or equivalent driver.
For herbs, this is genuinely good light delivered efficiently. Lower heat output than blurple-style LEDs, better spectrum, longer rated lifespan.
Coverage: 2×2 ft for herbs and leafy greens at full power. At 30W actual draw, it’s more energy-efficient than most competitors at this coverage size.
What I like about it: No fan — it’s passively cooled, which means it runs completely silently. If you’re growing herbs in a kitchen or living space, that matters. The white light also looks normal, unlike purple-tinted blurple lights that make your growing space look like a science experiment.
What to know: The SF-300 is a small light. If you’re trying to cover a 3×3 area or a longer shelf, step up to the SF-1000 or run multiple SF-300s. For a small tent or a dedicated 2×2 herb corner, it’s right-sized.
Verdict for herbs: The best quality-per-dollar at this coverage size. If you’re setting up a small tent for year-round herb growing, start here.

GE Grow Light LED
Best for supplementing a windowsill or lighting a single plant
The GE Grow Light doesn’t look like a grow light — it’s a screw-in bulb that fits a standard lamp socket. That’s exactly the point. If you have a lamp that’s already in the right spot, you can swap in a GE Grow Light and turn it into a functional plant light for under $20.
Coverage: Realistically, one bulb covers one to two small herb pots effectively. It’s not designed for a full shelf.
What I like about it: It’s the lowest-friction way to start growing herbs indoors. If you’re already wondering whether your herbs would do better with a little more light, a $15 bulb swap is the answer. No new hardware, no mounting, no timer to set up (you can put it on any lamp with a smart plug).
What to know: This isn’t a replacement for a proper grow light if you’re serious about yield. Think of it as a tool for keeping 1–2 herb plants healthy through winter, not for maximizing production. Basil and mint respond well; cilantro and parsley will grow but more slowly.
Verdict for herbs: The right choice if you just want to keep one or two herb plants alive and productive without any setup hassle. Not the right choice for a dedicated herb garden.

Barrina T5 LED
Best for long shelves and multiple herb varieties
The Barrina T5 is a strip light — long, thin panels that mount horizontally above plants. The design is ideal for shelving setups where you want to light a row of pots side by side, rather than a square footprint.
A standard Barrina 8-pack covers roughly a 4-foot shelf with decent intensity for herbs. The strips link together and run off a single plug.
Coverage: One 4-foot strip covers about 2–4 herb pots depending on placement. An 8-pack in a 2-row configuration covers a substantial shelf setup for under $50.
What I like about it: The form factor is uniquely suited to shelf growing. Panel lights are awkward on wire shelving — they’re designed to hang at a fixed height. T5 strips sit flat on the underside of each shelf, which is exactly how indoor herb shelves work in practice. Mounting is simple (magnetic clips or zip ties).
What to know: T5 strips are less intense per unit than panel lights. For herbs — which are happy at lower intensity — that’s fine. For vegetables that need higher PPFD, strips would need to be very close to the canopy. If you’re curious how T5 compares to panel LEDs more broadly, we go deep on that in our T5 vs LED Grow Lights comparison.
Verdict for herbs: The best option if you’re building a tiered herb shelf. Not the most efficient light per dollar, but uniquely suited to the form factor.

What to Watch Out For
”Equivalent wattage” claims
A light that says “600W equivalent” might only draw 60–80W from the wall. That’s not necessarily bad — LED efficiency is the whole point — but the “equivalent” number is essentially meaningless for comparing lights. Look for actual power draw (watts at the wall) and coverage area instead.
Heat and ventilation
Under-$50 lights from no-name brands often run hotter than more established brands at similar output. For herbs in an enclosed space, heat can be a real problem — it dries soil faster, stresses plants, and shortens light lifespan. If you’re buying outside the brands listed here, check user reviews specifically for heat.
Light schedule
Herbs generally do best on 14–18 hours of light per day. An outlet timer is a cheap, reliable way to automate this — you don’t need a smart plug, just a mechanical timer from any hardware store. Running grow lights on the right schedule matters as much as which light you choose.
Our Recommendation by Setup
Single plant or windowsill supplement: GE Grow Light bulb — minimal effort, $15.
Small herb corner or 2–3 pots on a table: SPIDER FARMER SF-300 — best light quality at the coverage size.
Growing herbs in a small tent: VIPARSPECTRA P600 for a 2×2 tent, SF-300 if energy efficiency is a priority.
Tiered shelf with multiple herbs: Barrina T5 strips — the form factor is made for this.
