I think @Mañ'O'Green said he was watering solo cup coco grows 7 times a day? I guess in 20 oz of coco the fertigation disappears pretty quick. I haven't tried it yet.I already have the AN sitting on the shelf collecting dust, I don't think I will use it all on a single solo grow, but hey what do I know, this coco stuff will be a new world for me...
