Hello I'm going to share my first ever grow I'm in laundry room with constant out side air coming in thru the dryer port hole. I also have a "air circulating fan" constantly blowing on it. Right now it's about a week just switched the fluorescent veg bulb with the flowering bulb and set the timer to 12/12. Great progress so far. I'm also using plain gardening soil which I'm adding organic flowering and bud fertilizer once every few days same with watering.
