I'll step in and clear up what this disagreement is about.
Per/Plant
Yes, if you grow a plant longer in the vegetative cycle, the plant will be larger and produce more bud than one grown on a 12/12 cycle from seed.
Per/Crop
Yes, if you grow a grow room FULL of small plants that are grown from seed with a 12/12 light cycle, you'll have more efficient use of your space in terms of the numbers of main colas. However, the weight of both methods will be almost the same.
You guys are discussing two completely separate types of growing.
In the Per/Plant method, you'll end up with a few VERY LARGE colas that weigh "X". In the Per/Crop method, you'll end up with many smaller main colas that add up to weight "X" with the same total weight in both rooms.
It is correct that you can get more crops per/year with the Per/Crop method and thus get more weight per/year.
However, look at it this way; Since you are growing for only personal use, massive weight isn't real important here. I grow three pounds of weed per/year for my own stash. That includes enough weed to give away to many people who have neither the means to grow it or the good health to even think of growing it. I don't sell ANY. I simply give it away until it's gone. I keep enough of each strain so that *I* don't run out before the next crop is finished, otherwise, it would be kinda dumb.
Because of my age, lots of my friends are also older. Lots of them now smoke weed or are eating Stoneys cookies. It helps them with their body pain and also lets them keep more of their own money to enjoy their lives.
Let's all help others by GIVING away your excess weed. You'll make a lot of people very happy.
If anyone is selling weed by using this site, you're lost. Go away. That's not what this site is all about.

Thanks everyone.
