US4420903- Shipping Container for Living Botanticals

A portable container for living botanicals such as rooting plants, bulbs or seedlings, composed in part of either inert and/or biodegradable fillers, characterized by securing the plant and its root structure against dislocation while insuring adequate access to water and/or nutrient vapors. Use is made of soiless growth media may be in a plant net container or a natural soil as the media, for initial plant growth and in a larger pot container for sustained plant growth. The larger soiless media portion is molded in two halves whereby the net rooting container may be compressibly secured in place by molded flaps. A given young plant may continue growing therein, suffering little or no shock in the shipping and transplanting process. Water and/or nutrient overfill is precluded by coactive relationship between an overfill tube and the larger soiless media portion.
