it was intended to reduce the amount of slaves needed which people did

well cotton needed to be separated by hand, and slavery was cheap

why do we use retting on flax seeds

dries it out, making it easier to pick

makes cell thicker, good for clothing

kills microbes, so you can have pure oil

the best time to harvest cotton balls are

when the cotton changes from yellow to white

when plant is dried and dead

when plant is mature but not yet completley dried
