with the strains i grow, i know that the daywrecker tends to grow lots of golf ball nugs all up and down the plant, the leaves are not so dense that the lower bud sights still receive nice light and grow well.
With the CO Tangerine, a bigger plant that is not trimmed will grow lots of worthless fluff buds down low with few ok nugs up top. Now with some serious pruning for bud growth, the tangerine responds and grows nothing but monster dense colas up top. If i was doin a SOG i would go with tangerine clones and prune all the bud sites off up to the tip at 5-7 days into flower.
So think about what strains you have and how they grow......
