I grow in straight coco coir and feed GH nutes. My lights on temp is around 80 and lights off temp stays around 74. I keep humidity around 55. I feed 3 times daily at around 900 ppm. I have 2 electric sky 180s on top and a pair of viparspectra xs1000s for extra light penetration. This is my first coco grow as I normally run dwc but the switch to coco has real impressed me. I only vegged her for 6 weeks and she is almost 6 feet tall. I had back surgery and have not been able to do any lst.
