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!!

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

Yes but not with regard to plants. HVAC personnel and wildland firefighters use the same information to make better decisions about what they do. HVAC guys use it pick the right horsepower for compressors and fans, they have about 5 charts to cover different elevations. Firefighters use it to predict fire behaviour and break it down every 500 -1000 ft.

By default the vpd charts do incorporate altitude because they use relative rh which is the amount of water the air can hold relative to sea level. I don't think this adequate though as it seems to ignore the physiological properties of the plant and how there is a difference in mass of particular substances that can be contained within air.

To explain this a little more I used to be an industrial hygienist. The ideal gas law is good for approximating things but ignores particle size so when you start adding contaminants that are not well modeled by the ideal gas law things get funky. It gets even more funky when you consider the body's adaptations to work in a reduced oxygen environment which we have at altitude. My boss who had been making these corrections was ostersized by many of his peers saying he was paranoid 20 years down the line people are starting to open their eyes.

Accuse me of anthropomorphic thoughts if you will.

thanks for the reply! much of that was over my head. i was a sociology major. lol.

only thing i'm aware of is how much horsepower you lose per 1000 ft elevation gain. which is considerable up here.

what elevation are you at roughly?

Something else I did not know until recently is that (forgive me if I use the wrong terms here) sporilation and infection rates for Beauveria Bassiana and other fungi are not consistent at different elevations. Citation- @Jewels

8000ft

So can you tell me why people perform unsafe acts at work?

 

[rkymtnman]

8000ft

wow, so you are up in the air too.

i would say that social mores have been adversely affected by the proliferation of social media in today's society which has led to an abundance of individuals that feel the need to draw attention to themselves thru negative behaviors.

lol!!! not too bad since i just made all that up off the top of my head!!!! sociology were the only classes that i was remotely interested in attending. and we had a lot of football players in them too.

 

[DopeDaniel]

Yeah, I kinda thought I was the highest fucker on here. Gonna have to drop a pin on my gorilla spot, might be 83 or 8400. I think it also makes a huge difference if your costal or inland geography.

I try not to complain too much about the elevation as I'm not gonna do anything about it other than move higher lol. It's for sure a stress on the plants, imo contributing to intersex issues but that's another topic.

not too bad since i just made all that up off the top of my head!!!!

Agreed, unfortunately it's not strictly an uber modern problem. That said, ice bucket, cinnamon spoonful, hot pepper fame awaits those who are brave enough. LoL you'll have the never dying loyalty of your fan base...for 5min.

i'm still blown away by the tide pod challenge. WTF was that about?

I sit around 5800 or so, and there's that noticeable difference in plants from here to Daniel's place.
