Best Herb Grow Kits for a Windowsill

A Click & Grow Smart Garden herb kit on a windowsill

A grow kit takes out most of the guesswork of starting windowsill herbs from scratch — seeds, growing medium, and containers matched to each other and sized for a windowsill, rather than piecing those together yourself. They’re a good fit for anyone starting their first indoor herb garden who wants a straightforward setup rather than sourcing seeds, soil, and pots separately.

What we looked for

  • Seed varieties suited to indoor light, not just whatever’s cheapest to include — basil, chives, and parsley handle typical windowsill light better than sun-hungry herbs like rosemary, which often struggles without a grow light indoors
  • An included growing medium or pod system rather than requiring you to source and mix your own potting soil, which is most of the appeal of a kit over starting from separate parts
  • A self-watering reservoir or clear watering indicator, since overwatering is the most common way indoor herb kits fail early — see our guide to windowsill watering schedules
  • Available refill pods or seed packs, so the kit doesn’t become a one-time-use product once the first batch of herbs is harvested or finishes its life cycle

Our pick: Click & Grow Smart Garden

This kit checks the boxes above by design: pre-seeded plant pods take the guesswork out of seed depth and spacing, a built-in reservoir handles watering on its own for a couple of weeks between refills, and Click & Grow sells refill pods separately across a wide range of herbs — so the kit isn’t a one-and-done purchase once the first batch is harvested. It also includes a small grow light, which helps herbs like basil that otherwise struggle on a windowsill that doesn’t get truly direct sun for most of the day.

The tradeoff is cost per herb versus starting from a bag of soil and a seed packet — you’re paying for the convenience of not having to guess at watering and light, which is exactly the appeal for a first-time indoor herb grower rather than someone who already has a windowsill routine dialed in.
