Yes it dies I will not argue that point. I just finished my very first tub of classic 20 20 20 and it lasted me 13 months. And I have about48 plants at a time growing. I am cutting back to 12 until I lose some surplus. I guess I am giving weed for Christmas this year. At least to those that use it.I give all the credit to Jack's. That stuff makes life so much easier.
