cells causing the branches to grow vertically while inhibiting lateral buds. “Pinching off” branch tips will reduce the auxin level and encourage bushy lateral growth as well as inducing new root formation.
    Synthetic auxins are more stable and last longer than the natural solutions. They can be used as an herbicide against broadleaf weeds like dandelions, but are most often used to encourage root growth and promote flowering.
Bacteria
    Bacteria such as mycorrhizal fungi and rhizobacteria are extremely beneficial in organic gardening. The presence of these organisms in the growing medium produces stronger, healthier plants that require less chemical intervention.
    Actino-Iron is a commercial soil additive that contains the Streptomyces lydicus microbe. Applied to the soil, the bacterium grows around the root system, protecting it from harmful pathogens while producing anti-fungals. Actino-Iron also contains fulvic acid and iron which feed the plant. For perennials, the effects last one growing season. For annuals, the life of the plant.
B-9 folic acid
    There is little literature on the effects of B-9 on plants. It appears to serve in energy transfer within the plant and inhibits the enzyme that makes gibberellic acid resulting in a bushier dwarf-type plant without pruning.
    B-9 can be applied as a spray or as a soil drench.
Cellulase
    Cellulase is a group of enzymes that act in the root zone to break down organic material which may rot and cause disease. Dead materials are converted into glucose and returned to the substrate to be absorbed by the plant.
    It can be used in water gardens to clean uporganic sludge.
Colchicine
    Colchicine, an alkaloid, is prepared from the dried corns and seeds of Colchicum autumnale, the autumn crocus that also produces saffron. The pale, yellow powder is water soluble.
    Colchicine is a very dangerous, poisonous compound that can be used to induce polyploid mutations in cannabis. Clandestine breeders started polyploid strains with colchicines, but none of the strains showed any outstanding characteristics, and cannabinoid levels were unaffected.
    Rather than explain how to use colchicine, I will advise not to use it. It is very toxic and produces no change in potency. I do not know any seed breeders that use it today.
Cytokinins
    Cytokinins are plant hormones derivative of the purine adenine, the most common cytokinin being Zeatin. They are synthesized in the roots promoting cell division, chloroplast development, leaf development, and leaf senescence. As an additive, cytokinins are most often derived from the Seaweed Ascophyllum nodosum.
    Added to the soil or sprayed on the plants, cytokinins help the plant make more efficient use of existing nutrients and water even in drought conditions. The result is a healthier plant and increased crop. Care must be given to application of cytokinins along with other plant hormones. Many commercial formulas contain a hormone cocktail which includes hormones like auxins and cytokinins that work against one another.
Enzymes
    Enzymes are biological protein catalysts that were first crystallized and isolated in 1926. Enzymes accelerate the rates of reactions but do not change themselves as a result of this action. Enzymes are added to fertilizers and growth additives to accelerate biological activity and speed nutrient uptake by roots.
    Most enzymatic reactions happen within a temperature range of 85-105°F (30-40°C) and each enzyme has an optimal range of pH for activity. Most enzymes react with only a small group of chemical compounds that are closely related.

Without a spreader-sticker, the surfactant sprays often bead up and roll off the foliage which makes them ineffective.
    More than 1500 different enzymes have been identified. Enzymes are grouped into six main classes and many subclasses.
Ethylene gas
    Ethylene gas is a growth regulator hormone that activates the aging and ripening of flowers as well as preventing the development of buds and retarding plant growth. It is most often used by vegetable growers who force ripening of produce heading to market. In gardening, it may be used to trigger flowering in plants.
Flower saver plus
    Flower Saver Plus is a commercial product that contains the Mycorrhizae fungus which enters into a symbiotic relationship with the plant by attaching itself to the root system. Mycorrhizal threads enter into root tissue then grow out into the substrate reaching more water and nutrients than the plant could
