my last grow had a cookie wreck in it. It grew and bulked faster than my other strains. The colas all fell over and needed to be supported. Unfortunately more than half the plant got brown and crispy (my fault, I'm sure. Not the genetics). It only yielded about 1.5 ounces of good bud and it should have been a good 6 oz plant.
Cookies n Chem on the other hand was an amazing plant. It smelled awesome, grew well and produced. It took 5 seeds to get that one plant tho. Of the 5 seeds, 3 were males and one of the females started growing balls so I chopped her down. Between cookies n Chem and cookie wreck, I feel the CW should be the better yielder.
