Time is a huge factor. I am an out door grower coming indoor. and i have done alot of research on this. I think .5 is a good goal even if it's your first grow if done right. People say a lb (448 grams) per light (1000 watts) so 448 divided by 1000 = .448 grams per watt. To many factors to say what is realistic.
