Set of 3 reusable PlantCollars to start growing hydroponically with PlantPod. PlantCollars hold stems of microgreens or plant cuttings in place and allow them to grow via hydroponic principles. Soilless growing can provide faster growth, a cleaner growing environment and less frequent watering. PlantCollars will keep the moist inside the PlantPod making sure watering your plant so often as with soil is a thing of the past. Doing so, house plants can be grown with only monthly watering.
