Cannabis farming systems and methods

A method to grow a plurality of Cannabis plants, the method comprises:

• growing said plurality of Cannabis plants within an interior of an enclosure;
• and
• maintaining said interior of said enclosure at a pre-determined humidity according to a method comprising:
• compressing a vapor-phase refrigerant in a compressor to produce a compressed vapor-phase refrigerant;
• said compressed vapor-phase refrigerant is supplied from said compressor to a condenser;
• condensing said compressed vapor-phase refrigerant in said condenser to produce a condensed liquid-phase refrigerant;
• said condensed liquid-phase refrigerant is supplied from said condenser to an evaporator;
• evaporating said condensed liquid-phase refrigerant in said evaporator to produce said vapor-phase refrigerant by condensing water vapor from said interior of said enclosure to maintain said interior of said enclosure at said pre-determined humidity;
• said vapor-phase refrigerant is supplied from said evaporator to said compressor;
• mixing said condensate with an additional source of water to produce a water mixture;
• wherein said additional source of water includes treated water, said treated water comprises water treated by a water treatment system, said water treatment system includes one or more water treatment systems selected from the group consisting of a filter, an ultraviolet unit, an ozone unit, a microwave unit, activated carbon, a cation, an anion, an adsorbent, and a membrane;
• mixing said water mixture with an additive to produce a liquid mixture;
• and
• supplying said liquid mixture to said plurality of Cannabis plants;
• wherein:
• said additive includes one or more additives selected from the group consisting of an acid, a macro-nutrient, a micro-nutrient, a carbohydrate, an enzyme, a microorganism, a vitamin, a hormone, and a pH adjustment solution;
• wherein:
• said macro-nutrient includes one or more macro-nutrients selected from the group consisting of nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur;
• said micro-nutrient includes one or more micro-nutrients selected from the group consisting of iron, manganese, boron, molybdenum, copper, zinc, sodium, chlorine, and silicon;
• said carbohydrate includes one or more carbohydrates selected from the group consisting of sugar, sucrose, molasses, and a plant syrup;
• said enzyme includes one or more enzymes selected from the group consisting of an amino acid, orotidine 5′-phosphate decarboxylase, OMP decarboxylase, glucanase, beta-glucanase, cellulase, and xylanase;
• said microorganism includes one or more microorganisms selected from the group consisting of bacteria, diazotroph bacteria, diazotrop archaea, Azotobacter vinelandii, fungi, arbuscular mycorrhizal fungi, Glomus etunicatum, Glomus intraradices, Rhizophagus irregularis, and Glomus mosseae;
• said vitamin includes one or more vitamins selected from the group consisting of vitamin B, vitamin C, vitamin D, and vitamin E;
• said hormone includes one or more hormones selected from the group consisting of auxins, a cytokinin, a gibberellin, a brassinosteroid, a jasmonate, a plant peptide hormone, a polyamine, nitric oxide, a strigolactone, and triacontanol;
• said pH adjustment solution includes one or more solutions selected from the group consisting of acid, nitric acid, phosphoric acid, potassium hydroxide, sulfuric acid, organic acids, citric acid, and acetic acid.
