Ventilation for Room

My set up will be in a small grow tent for about 2-3 plants (more likely 2 plants).

I am looking at growing in this tent: http://www.accesshyd...ml#.UsD7dfRDt8E

This will be in the basement.

I am not near a window.

The basement is a decent size, will I be alright with using the preexisting air in the basement to filter through to the vents?

I do not want to push the air outside. Thanks

well you need some fresh air circulation in your basement or the plant`s will use up the Co2 and you end up with stalled air with low amounts of Co2 (witch will give you a low/slow grow rate) you wouldn't like to be in a sealed basement either Im sure, tho for you its not low level of Co2 that would be the problem in the end, on the contrary

but as long as you provide some air circulation in there (cracked door/window) its ok to recirculate the filtered air from the tent




depending on what kind of light you plan to run in that tent I would say a small 4 inch budget ventilation with a filter to match would do the job just fine
