Plant hormones (also known as phytohormones) are organic substances that regulate plant growth and development. Plants produce a wide variety of hormones, including auxins, gibberellins (GA), abscisic acid (ABA), cytokinins (CK), salicylic acid (SA), ethylene (ET), jasmonates (JA), brassinosteroids (BR), and peptides.

Semi Volatile Organic Compound Testing. Semivolatile organic compounds (SVOCs) are a subgroup of VOCs that tend to have a higher molecular weight and higher boiling point temperature. SVOCs are of concern because of their abundance in the indoor environment and their potential for negative health effects on humans.

VOC's: Because of the materials used in its manufacture, vinyl will sometimes emit various levels of Volatile Organic Chemicals, or VOC's into the air for a period after initial installation. These toxic substances are harmful to the air quality of the immediate environment and can cause respiratory problems over time.

It Improves Indoor Air Quality Things like wall paints, polishes, glues, and fire retardants emit Volatile Organic Compounds like formaldehyde, acetone, benzene, and toluene inside a house that can be very harmful. According to a New York State University research, a jade plant can remove these VOCs.

Certain gases in the atmosphere resemble glass in a greenhouse, allowing sunlight to pass into the 'greenhouse,' but blocking Earth's heat from escaping into space. The gases that contribute to the greenhouse effect include water vapor, carbon dioxide (CO2), methane, nitrous oxides, and chlorofluorocarbons (CFCs).
