One strain and 4 completely different phenos. #1 was a mutant that topped itself. It is short and farthest behind. Did nothing but defoliate. It gave itself about 12 or 14 mains. Pheno #2 is the tallest and looks to finish first. Buds are hard and plentiful all the way down the cola. #3 and #4 are medium height and stacked very nicely. I think they will produce the largest buds.
