Hi i just recently purchased some Hairgrass for my planted tank.i have about 30 bunches of it,its about 1/2 inch in diameter.In each bunch looks like there is about 20-30 strains of grass..should i plant the whole bunch :?: or should i separate each bunch :?: Here is a pic of what i did so far there is about 6 bunches there and it looks like i should trim it down too...
