Ok stoners and growers... I've got a bag of Roots Organic Original and I need to make it stretch.! I know it's already got Coco Coir added but would it ok to add more Coco Coir to it to increase the volume.? And how much should I add to 1.5 cubic ft...? Oh and a side note.! I will be also using Nature's Living Soil in this mix as well...
