In order to achieve food and energy security, while at the same time eliminating the “food vs. biofuel” conflict, a transformational three dimensional multilayer farming, MLF, is presented. This exploits the third dimension. This goal is realizable by the disclosed means and methods to increase the 3D plant productivity, 3D yield, ton/m3/year, using ultra-compact ultra high density vertical structures. Each layer in the MLF system comprises at least one string of SanSSoil Growth Elements, SGEs, each designed to carry out multiple functions essential to sustain plant growth, and constructed in a manner to integrate these functions at low-cost. The networked strings of SGEs in each layer provide near self-sufficiency for growth, and in an integrated MLF system, achieve maximum vertical compactness and highest growth density. The multi-functions of each integrally made SGE include: germination, growth sustenance, localized delivery of nutrients, environment sensing, and localized delivery of illumination.
