I am wanting to begin my grow soon ! I have gotten everything in order and have my seeds germinating right now. I have Mother Earth coco +perlite (70/30 ratio) for my medium. And herbal hydroponics and cal mag for nutes. This is my first grow and I am not sure if I need to wash my coco coir? Or is it all ready to roll and be placed in the pot, right out of the bag?
