Rock phosphate: refers to minerals containing phosphorus anions and a multitude of other anions and serves as a source of phosphorus. Phosphorus is an essential to the process of photosynthesis and is involved in the production of all oils, starches and sugars. Both stress reducer as well as maturation facilitator phosphorus affects rapid growth while boosting flower and root development.
Rockwool: Inert, soilless growing medium consisting of woven, thin strand-like fibers made from molten volcanic rock and limestone, which is heated to over 2900 degrees F, extruded, and formed into slabs, cubes and blocks.
Sea Bird Guano: Sea birds eat only small fish from the ocean and depending on where the sea bird guano is harvested from usually provides a source for nitrogen, phosphorus and potassium as well as trace minerals. Sea bird guano is an excellent soil amendment.
Secondary Nutrients: Calcium (Ca) and magnesium (Mg) are considered to be the secondary nutrients.
Socket: The threaded, wired receptacle that an HID bulb screws into.
Sodium Molybdate: is a source of molybdenum, which aids a plant with the enzymatic function for nitrogen metabolism.
Sodium Silicate: Sodium is used for the osmotic or water movement and ionic balance in a plant and is paired with silicon, a compound of the cell wall. Together these two substances help to thicken cell walls and protect the plant from drought and heat extremes.
Organic Materials Review Institute (OMRI): Provides organic certifiers, growers, manufacturers, and suppliers an independent review of products intended for use in certified organic production, handling, and processing.
Parabolic Reflector: A lighting distribution control device that is designed to redirect the light from an HID lamp in a specific direction. In most applications, the parabolic device directs light down and away from the direct glare zone.
Perlite: Sand or volcanic glass which has been expanded by heat; perlite holds water and nutrients on its many irregular surfaces. Used as a soil amendment
