we're using a high tech aeroponic cloner, we should get at least a 60-80% success rate on those clones,
If this is your success rate, you had better junk your cloner and build a cheapo aerocloner for about 25 dollars. Mine has roughly a 100% success rate, and the root structure is massive.

If you notice, alot of people who use filters have them inside the grow room, suspended at the top of the room
I assume you are talking about an odor filter. If so, why bother having one if it's not in your grow room? That's where they go. That's where the smell is.
