The Dr Earth Fungicide seems to be very effective against pm as well. Stinks for a day or two but dissipates
I would think the Neem would do a good job at choking out the pm too assuming humidity issues are corrected

Have you tries adding neem cake to your soil mix?

The slower the air passes through the carbon the more time it has to absorb the odor. I believe the manufacturers call it "Contact Time"
Big ass filter with low air flow for the win

I felt the exact same way and I strongly resisted all the advice to spray MB. I burned myself out for almost a year trying to eradicate it many other other ways. The idea of losing my organic-ness made me start to lose interest in the grow. I am the only one I know in my area that uses organic methods. I won't use municipal tap water and I wont put anything in my compost unless it was organic certified or from pristine woods. For so many years I had zero PM and zero spider mites while everyone else I know uses things like Dr Doom and Hot Shots on a regular basis.
The problem is I have been working hard for years putting together a group of top notch selected clones and was not willing to give up on them to shut down. My friends would have my head on a pike if I dared shut down and encouraged me to spray strategically. So I finally gave in to the nuclear option in order to permanently eradicate PM from my perpetual and save those special ladies. It seems to have worked and just as @CobKits mentioned I got the job done with just a few ml.
Maybe there is a natural way to eradicate it, I wish I had discovered it. I did have one lady out of about 40 genotypes that was super resistant to PM, but it was not 100% resistant. I did lose some awesome ladies just because of losing interest in the grow during the PM battle RIP!

Yes it works very well with low flow, ~10W. I just had to make sure to use a thick enough layer that I get enough contact time if the fan speed is turned up. I use about 6 pounds of loose carbon in each filter, carved out a pattern on the top of an 18 gallon clip tote and taped on a paint strainer. Weather stripping to seal the lid and caulk to seal the tubing and any small holes. It is a lot of work and there is probably a better way.
To save a few more bucks I refresh the carbon every 6-12 months as needed by cooking it in a stainless kettle on a campfire and then leave it in the coals overnight. Just beware the strong fumes that come out of it while cooking

Hey Vegas, I do have neem seed meal in my mix, good stuff. I reamend with:
Fresh compost/EWC
Coop Poop 2-4-3 -composted chicken manure from organic laying hens
Azomite
Kelp Meal - organic
Crab Shell meal - organic
Alfalfa meal - organic
Indonesian fruit bat guano
Neem cake - organic
Fish bone meal - organic
Greensand
BTW Vegas these inline fans have simple linear potentiometers controlling fan speed. if I had a 5V or 12V power source, is there a simple way to rig up a controller that could automatically dim the fan based on canopy temp? Would I be better of with a separate controller for each fan or could it be set up to control 3 different zones?

Can eradicate PM you think? Should 60% rh considered an issue?

I am no expert on humidity and pm. Depending on temps I would say (VPD)
I tried the Dr Earth Fungicide and saw it knock pm's dick in the dirt. A regular spraying would definitely keep it at bay.
Only issue is that it is only available as ready to spray and in a hose end bottle. I was thinking of getting the hose end product and just figuring out what the dilution rate is so it can be used in my regular pump sprayer.
Organic "Stylet" oil also will keep it at bay if applied regularly

i really dont think anything eradicates PM like MB. the rest just "control it". as long as you have living plant tissue it can live inside of it regardless of if its expressing its external characteristics. you can have no symptoms whatsoever and then humidity changes and boom- it expresses itself because its still there. it will survive thru the cloning process and infect the next generation. the only way is to kill it and kill it entirely. ive only gotten it once in the last decade (dirty cut) and i took cuts of everythign, and as soon as they had roots i took everything down, bleached down the whole room, dipped all cuts (whether they were showing symptoms or not), and started completely over. did the same thing with those damn mendo super mites and now they are permanently gone. i dont use neem or azamax or surfactant soaps at all in my usual cycle as i dont need them once everything is clean.
i dont consider MB use as part of my grow. i consider MB part of a separate quarantine process i use before i grow and will only apply it to plants that wont be consumed, for genetic carryon process only.
i dont often take on new cuts from outside sources, but am literally only now flowering the new strains i got in Dec at emerald cup now they are thru the quarantine and grow-out process (and most of those were from dark heart but you can never be too careful). im fortunate to not have PM or mites exist at all unless i bring in foreign cuts. maybe its because i live in a high desert climate at 5000 feet (fleas cant live here so my dogs are stoked - mites prob. dont live here either in absence of an indoor grow). maybe its because im a hermit and i can count one one hand with fingers left over the number of people who have ever stepped foot inside my room. I've been growing indoor since 92 and back then PM was unheard of. it exploded in the late 90s after 215 when a bunch of people jumped onboard and clone trading became prevalent. It spread so fast back then that people thought it was a cannabis-specific govt conspiracy to wipe out the industry. and nobody knew how to treat it, the first time i got it in 2001 (dirty cuts from bay area), i tried in vain with Bacillus Thurigenesis and environmental adjustments but couldnt shake it. i literally stopped growing for years after that, and when i came back to it in 2006/2007 sulfur burners and BT and serenade (bacillus subtillus) were the rage. again, these are just controls. MB gets into the plant and eradicates it. much better to take a knee and lose a cycle or two and be clean going forward. and its pretty easy to setup a small quarantine tent in another part of the house for new arrivals. 2-3 dippings of azamax and one dipping of MB kills most anything. you could even use avid in such a setup if you were paranoid. roots too to be sure against fungus gnats. way better to go nuclear here than to put chems in your actual garden

that said these 'controls' are the ONLY option if you have an existing crop, MB is not an option on anything beyond clones and seedlings that are 90-120 days out imo. if you elect to finish out a crop that showed mold (either PM or bud rot), be realistic that there is prob still some degree of mold inside the buds and consider the H202 post-dip

This is all based on how in touch with your garden you are as well.
I check my shit all the time and treat at the first little dot of pm. Anyone who has a whole room full of plants covered in pm is probably in the wrong Career/hobby imho

you can call going nuclear during quarantine the "OneHitDone" process (naw J/K i dont want to associate you with nasty chems)
ding ding ding. take the time to ERADICATE it and life will be easy and chem free again

i hear ya but you could spend 40 hours in a room and still couldnt check all of the spots esp in flowering. thats why i will always dip instead of spraying. submerging gets to all areas. and the last thing i want to do is atomize these toxins into the air im breathing (even 'innocuous' chems like neem/azadiractin are serious irritants to the respiratory tract)This is all based on how in touch with your garden you are as well.

Funny I saw PM thought mites realized mildew. I add more small fans across soil to keep it drier more difficult for PM to establish. That helps keep it down in my garden.

Sure you can use a dht22 with mini arduino and a establish a operating range and fan can go on/off through ranges with a series of if tests within a while loop pretty easy to code.

Use pinouts for each zone to different relays controlling the fans one for each zone.

I use exclusively DC fans, because I can dim them and they are more efficient IMO.
I like the fan you pictured.
My tents are using Papst server fans.
I was wondering about using hydroton for aeration, how do you feel about that?
Btw I am still running my tent with CXB cobs, and have a 2nd tent with Cxm22s both do well.

No need to get Nuclear.
I was desperate & used Eagle 20. Never again. It works but is terrible for you & your plants.
I now use just a tiny bit of Organicide Plant Doctor. Safe, does work instantly.
Check it out. No poisons & will cure your problem.
Systemic curative & prevetative. Uses Mono & Di-Potassium.
Don't know why it's not a famous remedy?
Towards the bottom will give medical marijuana instructions.
Don't soil drench. Just foliar.

Also, instead of sulfur burning, I just use the Ozone generator in the area w/o plants when cleaning time. 24hrs in a sealed room kills it all.

Edit: I can't be sure that it's not neg effecting my buds. Something wrong last grow & im not sure if part of it was the Plant Doctor.
It does work against PM, whether it hurts my finished product, I'm still trying to figure out.
Just needed to add that.
