Hey all. Never used to have to worry about smell control, BUT, indoors now and close neighbors. Built a 3x3x5 cabinet/closet in my basement. Have two plants, one almost done budding and the other just getting under way. They are small plants, the bigger of the two is around 14 inches and compact, the other is in a 2 liter bottle, both 12/12 from seed.
Plant 1 is bagseed and stinky. Plant 2 not so much smell. Anyway, bought a 4 inch fan and filter combo from HTG supply, set up according to information gleaned from this site. It should be more than enough for my size cab. My passive intake is a 4 inch hole bottom left of cabinet, it has a 3 inch flange on the outside to prevent light leak plus black pantyhose on outside rim to discourage light leak. Inside it runs into ventilation tubing so as to let it flow on the opposite side of the filter above, you follow? The filter/fan combo has 5 inches of vent tubing between filter and fan, then another two feet running through sealed hole to outside of cab. It is sealed very well with clamps, etc... There is negative pressure evident since the door takes a little nudging to open and the inflow through the passive intake is strong enough to hold paper, filters, etc... to it while testing.
Temps steady around 80 degrees farenheit. Humidity varies between 55 to 65%, it has hit 70% a few times after watering. I understand high humidity levels can not allow the carbon filter to work. I also have ONA gel in a shallow pan mixed with water outside the cab underneath the outflow vent tubing blowing into it. There has been a few days when I walked into the house and smelled my plants and the ONA gel too, LOL. So, I am confident that the fan/filter is setup properly, but my question is does anybody think it's just the cheap filter from HTG supply, and that if I buy a Phresh or Mountain Air filter the problem will suddenly disappear? Or, is it possible there is too much fresh air coming into cabinet, not allowing all the air to get scrubbed? I can post pics tomorrow if needed. Some days, usually when the plants are due to be watered and they are dry, I can not smell anything even in the basement. Any help is appreciated. Peace
