Lugartis Terrarium Grass allows you to offer natural security to younger and smaller animals, humidity to more tropical enclosures and beneficial nutrients to grazers (e.g. Tortoises). Not to mention, the added aesthetics make your terrarium look amazing! Works with most substrates but you get the best results when using Lugarti's Natural Reptile Bedding. DIRECTIONS: Sprinkle a few seeds in an area you'd like covered in grass and water lightly. The more seeds you add the thicker it will grow. Continue watering as needed. Sprouts in just 2 - 3 days and will be inches tall in about a week!
