Bud worms/catapiller solutions?

I agree with FlyMuncher. Bud washing is key when growing outdoors. Its not likely caterpillar poop if no caterpillars are aorund or eating the plant. maybe bird shit or seeds or dirt kicked up from something. Good Luck!

Growing outdoors you will get many different types of debris on plants. If you don't have a bug infestation eating leaves or buds there is nothing to worry about. When growing outdoors it's best to do bud rinses at harvest to eliminate the debris from your product.
