Smell proofing a grow cab

I'm thinking about giving this thing another go. I have a nice sized cab that would make a nice grow box. My biggest concern is smell, this is absolutely crucial. The plan is to line the inside of the box with panda film, as the box is not air tight. This will also allow for multiple veg/flowering chambers. With activated carbon over the intake and exhaust vents, is this a feasible goal? Any tips would be greatly appreciated!

I think a zero smell grow is impossible. I mean - let's face it - pot stinks. And that's a good thing really because you don't want to smoke a joint and then be able to ace the SAT. No - you want to be wondering why you have a huge hankering for peanut butter and why all of the sudden even boring TV ads have become interesting to watch.

I digress.

Use a 'huge' carbon filter and don't grow hardly any plants. Get some Ona. And - when you open the door to your grow - only do it for a second or that dank will be all over the damn room.

We find wisdom in Sun Tzu's, The Art of War. Use multiple strategies to confuse and misdirect your opponent. Don't just put carbon filters on your grow box. Think outside the box.

1. Burn candles or incense if you can.
2. Keep potpourri in the room, or scented oils. It's Xmas, pine cone or apple cider scents are normal for a person to enjoy.
3. Get Renuzit odor killers if your stores have them. They eat up smells without just masking it with another smell. I find that two or three located throughout the room work great. They last 2 weeks and are a dollar each.
4. Mask the odor with Febreeze or Lysol spray whenever people are around as a last resort, not a great all-day strategy. Works wonders if people are only there a few minutes.
5. Get a houseplant that has a distinct woodsy odor. Or buy flowers.
6. Employ strange odors outside your area to misdirect. If everything is all roses as soon as they open your door, that will be suspicious unless it's that way before they get to your door.

Use all these and others. Cook smelly food. Find a hobby with something that smells. Use your imagination.
