I'm using 50% coco coir and 50% moss. There is more light than it looks, I was blocking the light to get a better picture. But, I have a 1000w HPS light on a motorized track and I'm on a 11/13 light cycle. The tallest one is about 6 inches from the light and I have an oscillating fan keeping the tops cool, can hold my hand under it and it feels fine. I use a blooming formula with epsom salts and hydrogen peroxide and flush with straight water every four days. The water I use is rain water collected in one of my many coolers. I am starting from seed and this is my first round. I'm in the process of weeding out hermies and males and getting my clones to root. All of my clones are going to make it except one...oops... I need some advice on getting tight buds from this strain. I know there are nutes for that but I try to keep things natural.
