LOOPS The vast majority of growers will likely end up at least base-lining with HIDs over a relatively flat canopy—mostly for reasons of simplicity. This necessitates reflectors, and for the purpose of efficient climate control, cooled reflectors. Efficiently cooling a light involves a...

QUANTIFICATION- how big/how high/how many Light Density While lumens kind of suck, they are the common measure of "quantity of light" that most lamps are rated with, so we have to use them anyway (at least for the time being). Ideal Light Density is the "amount" of light (number of lumens) that...

Fluorescents In a fluorescent lamp, electrical current runs through a phosphorus-coated tube of mercury vapor, causing it to "glow" and produce light. The actual process is more complicated than this (obviously), but we aren't here to design and build our own gas tubes. "Fluoros" are sold in...
