Moved the ladies inside...

I moved my ladies inside to finish. The garage is 16x20. This is where I will also start my inside grow on my next time. My question is do i need ventilation for smell, heat, ect. since growing in a large space? When I go into the garage I smell the ladies since they are only 2-3 weeks from finishing, however I do not have any smell in the rest of the house. I do not have company over and I will be using CFL's. I am not planning on filling the whole space up just what I need for up to 10 plants. Any suggestions are welcome.

Oh yeah, I do have an osilating fan going for air circulation.

Anyone...how bout one of the know it alls. LOL. My ass is going to sleep here waiting on an answer, plus went thru 1/8 of Headband.

you'll need a carbon filter gank, in less you don't have neighbours, nor friends, i've had six little girls at five week into flowering in me garage, and yes you could smell them girls from a twenty foot away

my closest neighbor is 50 yards away, and my wife and I dont ever have our friends over. We run a business and after work is over it is time to rest and Daddy gets to smog out, so very little company, of course my hunting buddy comes over to smog with me, we are like brothers, but other than that zero.

No one else with suggestions or answers to my question.

I think it would be best to use a ventilation system to ensure proper heat circulation in your grow room even if it is a large space. That way, you can be sure that the heat from the grow lights will not burn your plants.
