LPS vs HPS and LED NASA

cannabis is not close to lettuce or wheat; i do not think it ideal for our methods.

there are reasons that mh and hps are the two main lighting sources for indoor gardens. just as mercury vapor phased out, replaced by mh.

Found this too
*Low Pressure Sodium lamps have a very narrow color spectrum,
*but they may be used for "side lighting".

UV got the mercury vapor

Thanks for the help

More lighting

*Light movers provide more even lighting when used with high intensity lamps.

I tried to germ 3 NL seeds in space once, failed miserably. I dont recomend it

I was wrong

Low Pressure Sodium (LPS)

Low-Pressure Sodium are available most often in low wattages; although their lumen-to-watt output is the highest of any lamp, they function on a very narrow band on the yellow color spectrum which provides limited use to growing plants. While LP sodium lights maintain 100 percent of their lumen output throughout their life spans, they must be used, if at all, with an MH lamp to stimulate photosynthesis. Most indoor gardeners highly recommend HPS over LPS lamps.

that was useful

That presentation was referring to low pressure systems, not low pressure sodium. They are testing the effects of growing plants in a low pressure environment, like on mars, or a complete vacuum like on the moon. It had nothing to do with low pressure sodium lights, nothing at all.
