just updated the chart...
skotty's first grow was adjusted since the output of the HGL 345 Penetrator is really 279 watts and not the 290 I had in the chart. my LED Mythbusting thread has a picture of this...
and
i added a second grow by skotty where he got .61 gpw out of 579 total watts. 356 grams is what he yielded...
