I built a 7ft tall box in the garage 4ft wide 3ft deep. It has a shelf made of 2x4 and screen mesh 19 in from the floor. under the shelf is a small space heater and air intake vent w/ a forced air micron filter over the vent (to filter fresh air coming into the box). I have a 400w hps on top and two 2tube flourosgoing down the sides each end to give a little side lighting. a small fan inside on timer to circulate the air inside the box and an exhaust fan next to the light on top. I use rockwool drip unit with 8 plant stations and usually end up w/ 4-6 females (skunk #1) to flower. I always grow from seed (idoit w/ cloning so far). I've used this set up for 6 years now, works excellently, fills 12 mason jars & I grow 1x per year. A mason jar a month is more than enough for my use. As far as smell i just put a fresh dryer sheet over the exhaust port on top of the unit. Change it every other day the last 2-3 weeks of flower, as needed before that. After that a popourri spray inside the house 1-2 times a day and wifey burns candles regularly so I think this helps some too but she's done that longer than I've been growing so it's not something we do to mask the odor really
