The Window Sill Gardening Kits are designed to keep your small herbs and plants alive and well for 4-6 months. Beyond that, it is likely to run low on nutrients (plant food) and the leaves start to look paler.

The good news is you can re-use the plastic inserts, in fact we encourage you to do so! Simply remove the plant from its bottle, clean all parts well (no soap!), insert replacement Smart Soil inserts and you’re ready to grow again!

Each kit contains:

  • 3x TOP smart soil replacements
  • 3 x BOTTOM smart soil replacements (containing nutrients)
  • 3 x Germination Stickers
  • 4 x Blank Bottle Labels

NOT included but required: 3 x plastic inserts (sold separately)
