Described herein are compositions and methods relating to functionalized sands or soils.

A horticultural growth medium includes a filler and a binder. The binder is a moisture-cured, isocyanate-terminated quasi-prepolymer made from an organic polyisocyanate that includes a large proportion of 4,4-diphenylmethane diisocyanate. This binder system provides excellent curing properties and imparts excellent physical properties to the growth medium.

A method to grow cannabis is described, wherein the method includes providing and treating a source of water, mixing the water with an additive to form a liquid mixture, transferring the liquid mixture to a plurality of cannabis plants grown in a growing medium including a mycorrhiza fungus, and growing the cannabis using a humidity control method, then harvesting the cannabis plants. Trimming and grinding the cannabis along with use of environmental control methods including temperature, humidity, lighting schedules, and carbon dioxide concentrations are also described.

A greenwall cladding system for the growth of organisms such as plants and fungi on the side of structures, such as internal and external walls of buildings, is provided. Methods for the production of organisms on a greenwall cladding system, such as plants and fungi are also provided herein.

A biostimulant composition comprising an amino acid, a polysaccharide, a betaine, a polyol, an enzyme and a plant hormone is disclosed herein. The biostimulant compositions are useful for enhancing the biomass of a horticultural, arboricultural or an agricultural crop. The biostimulant compositions are also useful for enhancing at least one of enhancing protein content, sugar content, trace element content, resistance to bruising, or preservation capacity.
