I have two holes in the soil near my plants, these holes seem to big for ant nests however I do find a lot of ants near the plants, Do I really need to get rid of the ants? And if yes, what can I do to get rid of them?
Your ants are maybe farming aphyds on your plant,have a look under the fan leaves.http://www.theweedblog.com/how-ants-can-damage-your-marijuana-plants/ Good Luck.
