I don't like to argue so normally I avoid matter of factness when I post. But I've got plenty of money to use HID lights in my veg room I don't do this because using fluoros to slowly build a plant gives me a better yield from a plant with much thicker stems. Stem size is related to yield that is a simple observation. Additionally a veg room with fluorescent lights doesn't need air exchange that's a stoner myth, sorry fan companies I just said it. My 2 veg closets are completely sealed with 1 stand mounted oscillating fan (each) that doesn't even blow the plants it blows against the wall. No powdery mildew, no problem with growth and since my home is cooled by a huge central a/c unit the fluorescent lights don't need special cooling practices. I do run 2 veg rooms because I am always worried about Powdery Mildew since I had it about 7 years ago but I got rid of that Strawberry Cough pheno which was prone to it and never seen it again. For those using Google to find my post you may want to know my home is cooled to 69F in the summer and heated to 66F in the winter where my veg closets run year round as described above. So there it is there, again I am not here to argue so if you are so convinced you need HID lights and air exchange then by all means "grow the right way".
an excellent way to make mistakes to learn from.
