I thought about that, would probably be more efficient and just as cheap in the long run. How long does the ona last?
When you use the Ona fan with the gel it doesn't last that long. 1 gallon maybe 2 weeks or so. I did the friend test with both, the filters won and the Ona lost.
do you just setup your extra fan filter in the room your watering in rob?
Yup. My tents are in my "office", I just have the extra fan/filter sitting on a table. I also need a little extra protection during the last week or two before harvest and drying. It does the job very well, along with the other fans and filters. :smokebuds:
