good lord that's spot on! MY first grow was right at .2 per watt using about 600 watts of total CFL and T5 Panels... surrounding the plant on all sides and vegged for about 8 weeks. I was soooooo happy with 125 grams from 3 plants.

Second grow harvested using same setup as the first but with a few less lower watt cfls 26 watt, and more higher watt 42, and 68 watt cfls and added a few reflectors around the lights to direct the light onto the tops, T5's lighting the sides. total wattage was about the same 600w, Vegged 6 weeks, and harvested 6 plants with 'bout .5gram per watt.

Last harvest was with the same setup as before, no changes to lighting. Just changed to medium line of nutrients, and used a little better soil with amendments, shorter veg cycle as I had to go to a funeral in another state son only begged for about 5 weeks. Harvested 6 plants that were a little smaller in height and bushiness but the colas were much larger
Got about the same weight but in much bigger and prettier nugs.
