scrubbers n filters do i need them???

do i need a scrubber or filter for the air that passes threw the lights the lights are on closed circut with intake from outside threw lights and back outside if not where do i put the filters since im using a sealed room the only exchange of air i get is from opening and closing the door, should i get a device that i can put in room that cleans odors out the air??? do i even need one in my veg room??

Some grammer in your post would be nice

If your pushing through the lights then no. If you are pulling through the lights then maybe.

Unless you live in BFE then I would advice some odor control. You never know when someone will come by and try to sell you magazine subscriptions or something.

In the veg room, I don't really notice an odor besides a "green" smell. I woundn't worry about the veg room unless you do notice a smell.

Fresh air is a must.you need to bring fresh air in and then push your hot air out after its cleaned
