still smelly WITH CARBON FILTER?!?!

What do you guys do? ONA gel spray? It's not bad yet... but even outside the tent and even outside it can be smelled.

Thats obviously a problem. What size is the room, carbon filter, and exhaust fan?

Also, is the room sealed up pretty well?

yeah it's a tent. sealed fairly well. it's a 4.5x4.5x8 tent. 424cfm fan. large carbon filter probably 1.5 feet in length. dpes it matter that the Carbon filter is all the way at the top??? or does it need to be next to the plants?

Ok mate. A trick that im using is to put an ONA block in the ducting of your exhaust. I have 24 lady's growing and the smell in the room is eye watering. But with the filter and the ONA, there is no smell outside of the room.... Make sure also that your duct doesn't fill with water particles and clog up by flooding.... Tiny pin pricks in the duct somewhere will stop this happening, But be sure to have somthing to catch the drops of water from the hole's....

Hope this help's man. It sure has worked for me...

sounds like your fan and filter should be able to handle the smell.

how old is the carbon?
do you have alot of bends in your ducting reducing airflow?(duct should be kept as straight as possible as to not reduce air flow.)

excessive humidity can deactivate your carbon as well..
carbon can normally run 4-6 months before needing to be changed under normal circumstances.
