Seed Kit Tending and Harvesting Guides These Tending & Harvesting Guides have been consolidated to work with all AeroGarden models. Each "Series" guide was developed to work with Seed Kits associated with that series. For example, if you have an Italian Herb Seed Kit, the Herb Series Tending & Harvesting Guide will provide all the information needed for your Italian Herb Seed Kit. For Spring Bouquet Seed Kits, consult the Flower Series Tending & Harvesting Guide, and for Cherry Tomatoes, use the Vegetable Series Tending & Harvesting Guide, etc.
