yo, just read most this thread, and it is a great room with some great genetics in it! I think you know what you are doing but i wanted to point out not to use neem oil and sulfur burner in the same week. I don't know the specifics but somebody over at icmag told me and i took his word for it. I also wish i had that much room to get a good system going. And for sure get the extra 400 for those girls, they will thank you for it! As far as the mold goes the sulfur burner is the most effective thing that i know of. You can also increase ventilation that always helps control mold, Anyway man im subscribed and good luck in these coming weeks.
