Made from  plant by-products, EcoForms are an alternative to plastic pots. Our tests have shown that plants grow better in EcoForms than in traditional plastic pots due to their insulating design, which leads to thriving, healthy plants. EcoForms  do not deplete natural or edible resources. When used outdoors, EcoForms pots will last at least five years and even longer when used indoors. They are intended for use above the ground, and show no damage when exposed to freezing or thawing conditions.
