i was told since i have only one plant i prob. wont need an exhaust fan, and a couple of times a day all i need is to let some fresh air in the closet a couple of times through out the day is that true. I originally thought it was so easy to grow lol, it takes alot of work but is prob def. going to be worth it in the end. Hopefully the end wont take to long to get here lol. thanks for all the help:thumbsup:
