LPS vs HPS and LED NASA
Hey guys looking for HID stuff for Mogie and found this.
Check it out.
LPS cheaper and might be better than HPS and yes you can grow from LED's
Bad Shit short may be a little hard to read. It's like power point just page down and keep reading.
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
*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 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.
That's funny, nobody must have read the article just posted their opinion based on assumptions.
