AeroGarden compatible seed pods. These growth sponges are compatible with most hydroponic indoor gardens such as AreoGarden, iDOO, etc. Our seed pod kits are suitable for indoor hydroponic gardens or outdoor soil planting. The seeds after rooting can be easily transplanted into the soil. Healthy Root Development - Organic hydroponic growth sponges are made from high-quality peat moss, which are well-shaped and absorb water, providing the seeds with the perfect balance of oxygen and water for optimal growth. You can use the AeroGarden Hydroponic Growing System Seed Starter Kit for reliable germination and healthy root development. Hole Design - The top of the growth sponge has a small hole that allows you to put the seeds into it to ensure that the seeds do not fall into the water. Soak the Aerogarden sponge in water for 3-5 minutes, then place the seeds in the middle well, then place the seed pods into the hydroponic system and wait for the seeds to start planting. 50 Packs of Growth Sponge - You will get a pack of 50 replacement seed boxes. A sufficient quantity can meet your need to quickly start many hydroponic seeds, saving you a lot of time. All these Aerogarden seed pods go through a drying process before transportation, so there is no need to worry about mold.
