| Windowsill kit | Smart garden | |
|---|---|---|
| Upfront cost | Low | Higher |
| Light | Depends on your window (weak in winter) | Built-in LED on a timer |
| Watering | You, every few days | Reservoir; top up every 2–4 weeks (varies by model) |
| Ongoing cost | Seeds and soil | Brand pods (some allow reusable "grow anything" pods) |
| Best for | Bright windows, hands-on growers | Dim kitchens, busy people, winter |
Why indoor herbs usually die
- Not enough light: herbs want roughly 6+ hours of strong light, more in winter.
- Over- or under-watering.
A smart garden fixes both automatically. A windowsill kit fixes neither, but a $20–40 clip-on grow light fixes #1 (see our grow-lights guide).
Real cost math
Year-1 cost = device + (pods per refill × refills). Compare that with what you spend on store-bought herb packs.
Our take
Start cheap if you have the light. Upgrade to a smart garden if you've killed herbs twice or your kitchen is dark.

Frequently asked questions
Is a windowsill herb kit enough?
Yes, if you have a bright south- or west-facing window and don't mind watering.
When is a smart garden worth it?
If your kitchen is dim, you travel, or herbs keep dying on you. Built-in light and self-watering remove the two most common reasons indoor herbs fail.
