Here's something from the (OTHER BIG SITE) that's about odor control. WOW, I guess some others talked about my idea too. Just proving my point and moving on!
What methods can I use to remove smells?
The following tips can be used to cover the smell from smoking, or possibly a small grow.
Holmes Odor Grabber or True Air, available at Wal-Mart, Kmart or Target for under $20 US (A more powerful version is available for $29US.) These fan powered carbon air filters work great for small grows. One in the closet or grow room, and one in the adjacent room works very well. Replace the filters once a month (Necessary to keep the carbon active), which cost under $5.
Zeolite (Home Depot). Hang the bag in the grow room. There is also a similar product (“Odour rocks”
used for pet odors, in the pet section at Wal-Mart. Both products are between $5 to $8 US.
Potpourri in electric crock pots. Add scented oils , scented beads, potpourri mixes, spices, you can make it as strong as you like. I keep one near the main entrance of my home, fill it up once or twice and it lasts all day. You can find these near the craft section at Wal-Mart with the potpourri mixes and oils.
Place a small fan with a Bounce dryer sheet laying on the back of the fan, place the fan near your grow. The air is filtered by the scent of the sheet. Many of you may know already how well dryer sheets work.
Ona gel/liquid. Open container and let sit. Removes mild smell for up to two weeks before refilling with Ona liquid is required. The gel can also be placed near a fan (as above)
Glade plug-ins. They work okay, but won’t be enough to cover the smell alone. A few around the house can’t hurt, just change them monthly. Hang some car fresheners all over the place.
The best defense is fresh air. ALWAYS crack a window during the day, even in the winter.
Carpet sprinkle and vacuum products. You will smell it at for at least a few hours, good to use when company is coming over.
Charcoal for use on the bottom of soil, to absorb plant odors. Use an inch or so on the bottom of your soil to neutralize plant odors.
Some other quick smell-busting remedies:
Pine Sol
cook something.
paint something
brew some strong coffee
incense,
scented candles,
spray air fresheners
Add some of the above to your central AC filter, or furnace air intake. Also, dryer sheets work well in a window AC unit’s filter." Try these things in combinations and use often for the best results.
