I have a HLG Scorpion Diablo running with no co2.
Originally when I checked PAR against my 315 CMH's I discovered they measure the same at 15 inches so I figured why shouldn't they be able to handle the same distance as my CMH?
Took me this long to discover another form of measurement that has to do with Accumulation, like total hours or something, that is important? In other words just because my Large plant can take 2 315 CMH's at 15 inches fpr 12 hours, doesn't necessarily mean it want a 600 Watt Diablo at 15 inches for 12 hours? Even though the PPFD measurement is identical?
Allow me to explain: There are 6 boards on the diablo. Each one seems almost equivalent to 1 315 CMH by Par and footprint measurement! This is 3x the light of running 2 X 315 CMH!!!
So just because the individual output of one of the 100 Watt boards in the Scorpion Array is equivalent to a 315 doesn't mean that they want 6 of those on itself (plant) etc...
Can some one help me here. Seems to be my yield was the same or better running it over 2 feet, until I discovered the Photome Phone Light Meter and concluded that the intensity matched the CMH...
And I brought it down to 18 inches. I am starting to think 2 FOOT at maximum intensity over one of my Trees is best? Even 3 ft although I need to train my pants a little shorter because of minimal ceiling height!
