Anyway, uh guys, I need help (srry Bill). I need what my 6' filter does minus the smell removal. I need to protect my tent from critters crawling up the nice warm duct that terminates directly above my garden. I've got two draft blockers but that's not their job, so they do it poorly. They block draft just fine though. I don't want to waste the charcoal's finite ability to absorb contams by using it up during veg when smell's not an issue. I mean, it's never going to be much of an issue in the house but my neighbours have a right to fresh air - even if everyone, on either side and the two directly across the street, all grow weed. Apparently, I was the latecomer. How 'bout that! Seems suburbia ain't what it used to be.... thank fugging Elvis Presley on a pogo stick, else I'd've done myself in - marooned here as I am.
Anyway, I'm looking for the zero-cost DIY option here my friends. Your efforts in simply reading this are so appreciated so don't feel unloved if you don' have a skookum idea ready to drop. Good luck wit yer grows one and all, and hey Bill, here's yer thread back. I'm mostly finished wid'it, it could use a fill-up. Look, I promise I will get my crap together soon. (there's a weak sauce promise. creep!)
