Enjoy garden-fresh red or green romaine lettuceâ without all of that weedingâ with this seed kit for the AeroGarden Harvest Touch. Each box of six seed pods includes everything you need (minus the AeroGarden itself, of course) to enjoy a variety of freshly grown romaine lettuces at home. Simply insert the pre-seeded pods into the AeroGarden, add water and the specially formulated liquid nutrients, and let the AeroGarden do the rest. Most plants germinate within just days and are ready for daily harvests in less than three weeks. Most plants will continue to produce harvests for up to six months or longer.
