You can find an exhaust fan and carbon filter combination for under $300 that would be more than sufficient for your space and it would control smell for you. If you keep a negative pressure in your growspace and the exhaust is cleaned by a carbon filter, you can effectively eliminate the smells outside the space. You will be shocked at how much a single flowering plant can smell.

Best of luck, there's a lot of fellow texas growers on here to help you out. You'll never be alone here.

Yes for sure irydyum, as i watched them hook up a cover over my front door of my house, to see if the house was too insulated. I never thought a home could be ''too'' insulated, but i guess that there needs to be a balance of air flow through your house to keep harmful air thats not good to breath out of the home. Of course there is a balance which needs to be met so to keep out the cold, but allow harmful elements in the environment to escape is the slandered.:rasta:
