Cooltube venting

If i completely seal the ducting of my cooltube (air tight with silicone) that will vent outdoors. Should i still put it on an air filter? I figure if I have it air tight my plants smell wont be vented with the heat.

Thanks in advance.

Check out the attached picture.

The smell of your plants will not be vented by the cooltube if it is sealed properly.

Hope this helps.
