Publication number: 20200093071Abstract: A plant growing structure (100) designed to enhance the root quality, quantity, and architecture of plants grown in plant containers or in the ground is constructed from a plurality of support walls (200). The plant growing structure (100) enhances air circulation to the plant root system (20) to increase root growth and plant productivity. Channels (230) within the support walls (200) are designed with physical structures and materials that be adapted to address issues with aeration, infiltration, drainage, soil structure, root growth, plant nutrient uptake, plant pests and diseases, growing medium moisture, and growing medium microbial content. A liquid permeable drain platform (900) controls the amount and duration of water storage in the growing medium (50). The liquid permeable drain platform (900) may be used as a standalone device or in conjunction with the plant growing structure (100).Type: ApplicationFiled: September 21, 2018Publication date: March 26, 2020Inventor: Jason Paul Field
