I grow a bubba X deep chunk cross from Cannacopia and I have decent yields, not huge but decent and I have found that the more colas you have on your plant, the better the yield will be. I have tried a SOG with bubba but it seemed like they were getting too many side shoots getting tangled up together and it was basically a cluster fuck. I have had great luck growing them out big and topping the shit out of them. I have one growing now that has 8 colas and is 3.5' tall and just as wide. Only 17 days of flower and I have lots of little buds with white hairs and young trichomes starting to show. I love growing bubba and I love making ISO hash from the trim, it is some of the best I have ever had. And on this cross from Cannacopia the leaves always turn a dark purple about a week before peak harvest, even in higher temps. It is like a little calling card telling you the time for harvest is near. I am also growing a Bella Donna from Paradise right now and I cant wait to see what happens with that.
