/sigh so i woke up to the smell of weed coming from my utility closet again today, this really sucks i thought i had fixed the issue with the duct tape but i guess not, i walked around the out side of my house inspecting for smells, i still haven't detected the odor out side yet but if the smell is getting to my utility closet threw the attic its only a matter of time before it smells out side and I'm only 2 weeks into flowering. I really hate the way this whole thing is set up it fucking sucks that i cant just go sit on the exhaust side of my ventilation system and take a whiff for odor, i knew this would be a problem but i did not know how big of a problem it would be i didn't expect to have any odor leaks, i figured it would be a problem months down the road when my carbon filter was going bad or something like that. When i walked out side today i noticed that the wind was particularly strong, i have also noticed that the smell is not particularly consistent some days it seems stronger than others and some days i don't notice it at all, i am wondering if the wind flowing threw my attic could be negating my negative air pressure at times and causing the odor to escape into the attic around the hole i have cut from my ducting, it seems possible but unlikely the negative air pressure in my closet seems quite strong.
I really wish i had a weed odor detector, i know it probably sounds dumb but i am still not sure that this smell is even weed, it smells very dank and musty almost like old oil and a lot like weed but it doesn't have the fresh growing weed smell that my grow closet has, i am pretty sure the odor wasn't there before but i suppose it could have been and I'm just noticing it now because I'm extra paranoid. I dunno it just seems to coincidental to me for it to not be the weed, in the utility closet there are holes punched in the wall for utility stuff and it is the only room that i am smelling anything so my guess is that the smell is getting into the attic unfiltered some how and then seeping back down into the walls and into the closet where i can smell it.
Right now i have very few solutions left to fix this problem the main one being to change the position of the fan and the filter from filter-hood-fan to fan-hood-filter this is probably the best solution it however is the one that i like the least, doing this would require me to take a part my entire grow room and it would be a real pain in the ass to mount my carbon filter at the other end, it would however help me to identify the source of the problem if the problem is still my hood or some where in my ventilation i would know because the issue would be resolved. Not only would this be a pain in the ass it would also create other issues like the sound of the centrifugal fan spinning and the whooshing of the air that is currently being dampened by the carbon filter, on the other side of the grow closet is a room that gets used a lot and stealth factor is of the utmost importance to me. The only other real option i have that might be a solution is to weather strip the ducting hole in my ceiling so that if the issue is being caused by the wind it can no longer pull smelly air from the grow room, as i said before it doesn't seem to me like this would be the problem because i have a lot of negative air pressure, then again the odor coming from the closet isn't really that strong either i mean it smells but it doesn't really reek like my grow room so maybe it is the problem. I also might try removing the hood from the ventilation system to see if it is the cause of the problem i would rather raise my temps a few degrees than have to worry about this shit constantly plus it would also help me to determine what the problem is.
