I think I know why but...

quick summary: my flowering plants in a coco/hydroton/peat mix will stop "smelling" during mid flower. i usually use southern ag fungicide (hydroguard ) during all of veg and start of flower. but at some point in my last 3 grows, they just stop making the whole grow room reek. to "fix" it, and this is my 3rd time doing this with success, i stop the southern ag and give them a 5ppm dose of chlorine (pool shock). after 2 feedings with the chlorine, the plants start smelling again 24/7

so the question: i think i must have some root rot issues going on, the southern ag doesnt' stop it, and only the chlorine gets the roots healthy again and they smell .

anybody else have this same issue? i've been on forums for awhile and never heard of a root rot issue causing plants to stop smelling.

or is maybe the chlorine stripping off some layer on the roots?

i'm kinda stumped. but i just dosed them with chlorine 2 days ago and the whole basement smells (in a good way) now.

thoughts??? let em rip!!

Maybe swap the hydroton with some perlite?
I use hydroton, and love it.
I do think however, the surface of it, can hold more moisture then we realize. Not allowing the pots to dry back quick enough maybe?
Perlite, I prefer the large chunk myself, when I mix up my medium blend.
I also do not use any fine coco coir except in my worn bins, anymore, as coco husks (for me) are far more versatile.
In my medium mix, and as a mulch cover, in my pots.
I do have a small jug of southern fungicide, I used a bit last year maybe.
Now that I make LAB's and use it regularly, most of my issues I was chasing, seem to have gone elsewhere, for now.

@Captain Sternn : i bought a brand new bottle of SA for this grow specifically to see if maybe the last bottle was just old and not helping in the last 2 grows. but same results this time.
@webeblzr i should have said i use sunshine mix 4 which is peat and perlite. but i have examined my roots after harvest (i grow in 2 gal pots) and the root mass looks fantastic.

i'm not against using pool shock. i've used chlorine during my dwc/rdwc grows with much success. and it's dirt cheap.

the bad part is that if it is indeed a root funk issue causing the lack of smell, i can't really remove the plant from pot to examine roots.

well, maybe some others will chime in if they've seen this phenomena before. thanks for the help you 2 though...

I had the thought that if it was a wide spread problem in the roots, maybe somewhere along the way it would be pretty likely to manifest as pytheum ?? stalk rot ? Likely enough ? that if it doesn't, maybe the fading aromas have some other cause but I'm without any idea what that could be. Could it be killing some beneficial fungus, if there is such a thing ?

oh well, like i said, not a big deal, i know what brings back the smell but not sure why it goes away in the first place.

i'm gonna stick with either a very mild case of root funk . or this is just my imagination. lol. but i am able to recreate both the issue and the fix in 3 straight grows. only variable that has changed is the strains of what i'm growing.

was gonnea keep out of this but come on don’t push fake bro sci, everyone deserve their own views but ur saying it like this makes it sound like this obvious good bacteria is def not ur issue if u were having one. Did u state even why ? nothing , no facts , no info and also no proof. that’s preety degrading when every pro bacteria/fungi study would disagree with that even for hydro .


keyword only diff is ur growing diff strains, hmmm that’s ur big obvious why. Don’t blame something that in no way was ur terp enhancer or loss. That makes zero sense even if u had root rot or a medium base. That very product would only be a defense and an aid . Has nothing to do with ur inputs or terps. If anything enviromental and strains are biggest map to such.

example, I grow 100’s of new and previous pheno’s a year, am I lossing terps being organic and also def pushing my microbe and def fungi dominates in my medium and def doing such on day 1 - to harvest ? well I disagree it’s not possible for a pool shocker besides the smell of the pool shock would be only ur only gain and also that stuff is bad for You and also hints why it’s not ag or food approval , ain’t touching that and def know u are what u eat.

well I grow in same medium both indoors and out ( year after year and never throw away ) and I know I’m def not shocking my mediums to death, I know never have I lost smell or value of quality by good bacteria or fungi , it’s def other things and factors like genetics to environmental that def can and will . 2 days after u destroy ur benficals u gained terps? That makes sense ? I’m no troll but come on even if the sterilization saved ur crop it’s not gonnea give you two day terp enhancement or gains .

‘’if anything people will take clones or grow same but beg and ask , how bh can ur weed be such good quality or so smelly and tasty? It’s not one thing but it’s def good microbes and fungi but also def enviromental and good strains. Reminds me of modern ag sold groceries, yeah cardboard no flavor and also sterilized to death. I’ll take a homegrow and organic anyday and hints why if u care about ur health I would suggest to.

hmmm don’t see anywhere this species is bad… def helps me and even for foliars against disease and molds

Bacillus amyloliquefaciens is a species of bacterium in the genus Bacillus that is the source of the BamHI restriction enzyme. It also synthesizes a natural antibiotic protein barnase, a widely studied ribonuclease that forms a famously tight complex with its intracellular inhibitor barstar, and plantazolicin, an antibiotic with selective activity against Bacillus anthracis.[1]

It is used in agriculture, aquaculture, and hydroponics to fight root pathogens such as Ralstonia solanacearum,[2][3] Pythium,[4] Rhizoctonia solani,[5] Alternaria tenuissima[6] and Fusarium[7][8] as well improve root tolerance to salt stress.[9] They are considered a growth-promoting rhizobacteria and have the ability to quickly colonize roots.[10]




I only replied cause ur pushing this agenda of let’s pool shock and it instantly fixed and give ya boost of terps and qc. if u truly believe this go for it but I’m def gonnea keep on my growing choices cause I know when I was using sterilizers my weed def was not nowhere as good but also less flavorful and def not stronger smelling.

TBH i didn't read past this. waht fake science am i pushing?

you explain then: same timeframe roughly (5 to 6 weeks into flower) and smell goes away, had been using SA, added chlorine and plants started smelling again.

and p.s. even the wifey agrees that the smell went away.

your turn...

if ur sayings u can smell this bad smell in ur water/medium, so what ? Ur not under current …the “smell” your referring to is just the bacteria producing beneficial enzymes and that smell is a good thing , hints why in hydro they reapply every 2-4 days . omg natures produc(ng something I gotta buy in a bottle with a fancy label and cost 100x more and no Bennie’s , u ever even use organics cause so much that’s beneficial smells and that’s so much of the beneficial . Those bacteria’s are producing and releasing what so much of this dumb industry pays for in a bottle. Do a fish protein or some bat or seabird And don’t tell me they aren’t stinky, but does it enhance the terps. that’s a well known secret on terp enhancement actually and many og’s cement in their organic poo’s and bacteria/fungi for such.Stinky but those exact bacterias that are part of that creature creates special bacteria for them, like u are to ur mother

Since u obviously dont want to have a real discussion or cant read , its ur choice to make a thread with zero facts or really anything but bro sci

So Enjoy ur sterilized weed,its ur choice .

heck if that’s true than why don’t we all just pool shock our non hydro mediums and form what ur saying they will be soo much better. Yeah ur pulling those facts

show me ur weed, I’ll show u mine? Hahahha



also many pheno’s and strains don’t even have smell till end and def less chances till mid stage flower, I bet if u didn’t do that and still did SABF the smell stoll would of came from ur plants . So what’s ur point besides that? i def can tell u no matter what u did even enviromental it’s the strain dependent on when and how much terps exist, it’s the farmers process and also choices of the end result. Blame SABF for that? lol

An open discussion without the negativity would be great. Please moderate your self.

not sure what you're going on about. did you read and comprehend anything of what i wrote? the actual smell that the plants give off during flower goes away. but then comes back.
So Enjoy ur sterilized weed,its ur choice
you do know that chlorine is a tertiary nute for cannabis, right???

so you are calling me out for bro science by using confirmation bias (bro science) as your "evidence". too funny.

I have a thought that this could be related to a natural slow down in transpiration that happens about this time. I think you are at elevation, how high? what's your vpd?
8800 ft. i'll have to look my vpd up but temps and RH are usually about the same every grow. 80F and 40%Rh at this stage. last 2 weeks i'll drop temps by at least 5F. and also drop led intensity

could you explain the monocropping part?
I don't know if you use any inoculants and the amount of microbes in things like sunshine 4 and promix isn't really sufficient to inoculate the roots. The microbial population is then dominated by southern ag through veg. I will not argue sterile vs. living but it is difficult to ride the line between imo. Not impossible.

Even if you do use inculants there also isn't typically a sufficient diversity of microbes in those to get where I want to be with my version of living soil.

This part is what gets weird in my mind. @JL2G and I have grown the same cuts that come out with some pretty noticeable profile differences, the biggest difference in our grow environments is probably the ~3000ft of elevation. I think he gets more accumulation of the low boiling terps.

If the plant isn't transpiring as much because there is no longer vegetative growth then maybe the terps aren't being volitized either? At altitude this effect gets multiplied because of lower pressure and higher evaporation rates.

I don't think we should be targeting the same vpd as people at lower elevations, but don't ask me what it should be, idk.

i try to keep things easy so pretty much the last decade has been either chlorine or southern ag. i did try something called TPS Billions which is all 3: mycos, bacteria and trichoderma but i only used 1 bag of it a few years ago.

i know the vpd charts are based on rh% and temps but have you ever seen anything that also incorporates altitude into the equation??
