I am currently growing white widow autos from ilgm and, without and training and topping, they range from about 22” to 30”. My first grow I topped them and I currently have 10oz in jars from 4 plants in the cure. The bud density varies, but I made a lot of mistakes, so I don’t think that run was a good indicator of potential bud density. Maybe this second run I am in will have more consistent bud density. They’ll be done in a month and I’ll let you know how it turns out.
White widow autos aren’t the higher yielding autos offered on ilgm, but the thc% is high relative to some of the higher yielding ones. If your looking for high thc and yield, the amnesia haze auto might be good for you.
Enjoy the selection process. For me, it’s like ordering at a restaurant, I can never decide until everyone else is ready to order and the waiter is standing over my shoulder waiting. I finally pulled the trigger on getting some LA confidentials after mulling it over for weeks.
