Dedicated followers will remember me making much of my home-made activated carbon and filter...tedious and laborious the former, a simple construction project, the latter.   When installed with 5”rvk, I was bowled over by the complete attenuation of pong at the other end.  Now, read on...
  Recently, I decided that the filter was mounted at the wrong height in the room and there’s no denying the occasional wafts of garlicky-vanilla aromas in my back yard.  Clearly, I’ve been ignoring the fact that the filter was failing.  It probably managed a couple of months of effective use and, as importantly, proved a point to me (whether that point is learning where to draw the line with “how-to” videos, we’ll see).   TCALSS (is that a recognised abbn?), today I removed the end of my filter, poured out my 3-5mm granules and refilled with aquarium-grade activated coconut charcoal.  It takes about 7 litres of granules (just under 5kg) to refill.  It’s more like 2-3mm and my outer mesh just about contains the smaller bits - point is, I’ve multiplied the active surface area just with that, never mind that this is now properly activated coconut.  How anyone can use extruded pellet carbon, I’ll never understand.   And, this time, the smell at the outlet is...well, not there.  Previously, there’d always been a sweetish tang to it but this stuff is the god’s bollocks.  All lingering smell dissipated and cleaned up.  26 quid for 5kg, no brainer.   While I was still kidding myself, I wondered whether the fan was just pulling too much air through the filter, so I’ve just wired up a WAC1 speed controller - brilliant, I’ve set it on 3 and the rvk is just a whisper now.  The fan operates at all 1-5 settings, and the controller is silent.  Another 26 quid.   Basically, more lessons learned - and all the time I was advising others about smells and ventilation.  Background anxiety seems to have disappeared in a puff of smoke, too.  

@npx2020 ahh well, it will be a long night tomorrow. It will give me a bit of relief though in knowing it will all be safer in there.  Im not too worried about flush as I'm not a heavy feeder anyways. I've just got too take it on the chin.  Humidity has been crazy recently.    Cheers   GM 

I´m using grow, bloom and top max from bio bizz. From now on only water and it´s going to be in a couple of days. thanks
