First off, you need more light. I recommend HPS, other people may like other shit but I recommend HPS. Buy a big ass fan to keep the area cool. Don't worry about the smell until flower. It'll get a little stinky in preflower but no worries. Grow her under you've reached about 1/3 your space. I usually keep her vegging around 55 days, I get a nice 3 to 4 foot plant And about 3 lbs off her. I top multiple times, check out my last batch. I topped her like 4 6 times and have tops all over the place. Use LST, this will hook you up like crazy. It allows light to reach areas where it normally cant. good luck
