Bud with red hairs is more potent, it's because the grower let the bud reach its maximum potential. Buds without red hairs were harvested too soon.
well first of all all female plants have hairs whether you see them or not, secondly the color of the hairs only has to depend on the strain of plant. Some will be green others red, orange, white, or puprle. male plants dont always have hair, sometimes they do. The color of the hair doesn't particularly determine the quality, though i've never been disappointed with nice red hairs. Green on the other hand, the most of the bammer i've seen has been just straight green, but also the most chronic- straight up knock you on your ***- bud has also been just straight green. The quality of the bud has not to do with only the breed, but also the skill of the grower, cause he has to harvest at the right time, make sure the plant gets all that it needs.
white hairs are not good man
that means that the bud was not left on for long enough and was not able to mature and get to its peak potency.. by feeding it what i said before, u dye the hair..
