Strain
Had a hard time recovering from gnat larvae damage but was to be expected with the nutes i was using. FoopCanna is not a product that should be used in drain to waste set ups and id imagine deep water culture would also be a nightmare. In a light soil it does great but brings the gnats to the party like a it has gnat hormones in it. Idk what it is out of all my grows including dirt from my yard in my closet vrow ive never seen gnats so attracted to a product..nematodes a.must
