First and foremost itsmehigh hit the nail on the head. Change your environment so it can't grow.
Different levels of heat kill different molds. For example PM can be killed by raising the temp in the room to 100 degrees for 1 hour. 90 will do but I found using 100 gives me a little room for error.
Vinegar
Apple cider vinegar is toxic to powdery mildew because of its high acidity (low pH). Use it at the rate of 1 tablespoon per quart of water several times a week . Some gardeners recommend alternating using vinegar with potassium bicarbonate and milk..
Powdery mildew is sensitive to heat. Neither species will grow at 90 F (32 C). and will quickly perish when above 100 F (38 C). To get a complete kill maintain the temperature for an hour. This may not be a feasible option in most indoor gardens for several reasons. The first is that it may be difficult to heat the space to such a high temperature. The second is that even a single peak of 100 F (38 C) affects the growth of plants. Vegetative plants with flowers or fruits in mid stage growth (weeks 3-7) may stretch a little from the experience. The heat treatment has relatively little effect on first and second week flowers or flowers nearing maturity. You can minimize heat impact on plants in several ways. Heat the garden at the end of the day, as the lights are turned off. Since the plants are not photosynthesizing, they have lower water needs. If the plants are being grown hydroponically, lower the temperature of the water to 60 degrees. Keeping the roots cool will help the upper plant parts beat the heat. It's not difficult to do this, even if you don't have a water chiller. Just add ice to the reservoir or flow through system. Roots of plants growing in soil can also be cooled using thermal ice packs at the base of the stem. The heat treatment should kill off most of the fungus and its spores. The chances are there will still be some fungal re-growth. These can be eliminated using spot treatments.

Use a HEPA13 filter, it will trap 99.97777% of everything.
OMG!
Full STOP! Do not use UV light to sterilize air. UV light alters the DNA of whatever passes through it, this causes whats called thymine[URL='https://www.google.ca/search?client=firefox-a&hs=597&rls=org.mozilla:en-US
fficial&channel=fflb&q=thymine+dimerization&spell=1&sa=X&ei=uPYSVP7uHZD4yQSysoKgCw&ved=0CBsQvwUoAA'] dimerization[/URL]Pyrimidine dimers are the primary cause of melanomas in human beings.
Pyrimidine dimers are molecular lesions formed from thymine or cytosine bases in DNA via photochemical reactions.[1][2] Ultraviolet light induces the formation of covalent linkages by reactions localized on the C=C double bonds.[3] In dsRNA (double-stranded RNA), uracil dimers may also accumulate as a result of UV radiation. Two common UV products are cyclobutane pyrimidine dimers (CPDs, including thymine dimers) and 6,4 photoproducts. These premutagenic lesions alter the structure of DNA and consequently inhibit polymerases and arrest replication. Dimers may be repaired by photoreactivation or nucleotide excision repair, but unrepaired dimers are mutagenic. Pyrimidine dimers are the primary cause of melanomas in human beings.

that surprised me "woods"
thank you
thank you
Yes, UV damages DNA (kind of the point), but this is not contagious. As long as you dont pass through the ventilation system yourself, I think you will be ok...

YOU CANNOT INCREASE CBD in a plant !!! Specially the way you're yappin
It's no wonder, there's so much misguided info out there.
Your right, My bad it's CBG, spell check takes over sometimes. Not my claims, or test results. Just passing on someone else's info, don't shoot the messenger. Can't you reply to a topic with out insulting the person? It's your right to express your opinion, but there is no need for disrespect. You hurt my feeling. I can "yap" all I want........didn't your mommy teach you "if you can't say anything nice, shut the fuck up"

"Use a HEPA13 filter, it will trap 99.97777% of everything."
Hepa will also be utilized, but the key word is trapped, not killed. The filter will only hold the living spores, these filters are expensive and need to be replaced frequently. When being changed there is a risk of dislodging spores, and releasing them in to the area, a low level uv will kill the spores in the fan coil unit. Hepa 8 will remove mould spores. 13 is a little overkill that will remove viruses and bacterial, not needed in my opinion. We have a protocol in place so that no one will be exposed to any harmful levels of o3, 50ppb is a safe level, O3 has a half life of about 1hr, so it's easy to control the area in which O3 will be used safely. The high levels of O3 will only be used once the facility is empty of humans, to shock treat an area, or an empty grow room.

Did you even look at the test results? You should take your own advise. Not my claims, no affiliation, and I'm not using their product. I concur thc will degrade to CBn, dam spellcheck!!!

140 F (60 C) for 15 minutes.

This point is moot, because you're not passing yourself through the UV light sterilizer.... unless you're into that kind of thing....

No it is not, if you are in a room that is being treated with UV light get the fuck out!
Pyrimidine dimers are the primary cause of melanomas in human beings, these are formed when passing through the light and come out the outer side, if your in the room you are exposing yourself to them and increases your chances of skin cancer. How can that be a moot point. Some people care about these thing some don't you have been warned.
There are protocols around changing the filters, SOP's. These filters are used up to a level 4 lab around the world and have been for 50 years no issues changing them out. What is the cost of a failed crop compaired to a few hundred dollars for the filter. I can think of 4 LP's who wish they took my advice and installed Hepa 13's in each room. Just think re-call. http://en.wikipedia.org/wiki/Biosafety_level
My next door neighbor is the guy who designs and certifies these labs for the last 40 years.
Different temps for different molds.

Sorry woody your going to need to elaborate on your concern. I'm talking about producing ozone or O3 with a uv light within the confines of the fan coil in the HVAC system. Nobody will be exposed to the light itself. How is this a health risk? I'm no scientist but from what I can assertain from "Pyrimidine dimers" is that they are formed from direct exposure to UV light. Correct? So if nobody is exposed to the uv light it's a moot point. Unless I am misunderstanding and "Pyrimidine dimers" are produced by uv light and become free floating partials in the air. Then I can understand your concern. But that's not how I'm interpreting "Pyrimidine dimers" from my research. The last thing I want to do is expose any of my employees to any hazards, but uv light sanitizers are a common thing in many residential and commercial applications, to sanitize the HVAC systems, by producing O3.
The biggest difference between a clean room or lab is the high humidity of a grow room. These filters will contain/trap the mould, virus, bacteria, in a lab environment and dry out and die within the HVAC. But in a high humidity situation like a grow environment, the contained or trapped spores can actually grow within the filter. By adding uv within the confines of the HVAC, the filter will be catching dead spores. Defiantly not an HVAC expert but that's how I understand it.
Cheers Itsme.

I agree with itsmehigh regarding the UV exposure. You'd have to expose yourself to the UV directly to be an issue. My guess is your set up would be self contained and you'd never be at risk for accumulating exposure to the rays. Pyrimidine dimers are a result of DNA being exposed to high energy UV light and is not contagious nor air borne.
Basically, the issue of melanoma occurs when damage is accumulated such that mutations, such as the dimers you refer to, ultimately resulting in uncontrolled inappropriate growth of skin cells. Most melanoma is pretty treatable but about 5% or so becomes very aggressive and mobile; usually moving to other organs via the lymphatic system, such as the bone, liver and brain, where it disrupts normal organ function.
I think your concern is only legit if you're somehow being exposed directly to the UV light you're passing your air through. I'm not sure of the numbers but figure out how the UV light compares to a day at the beach...
The company's pre-programmed setting is 140 F for 15 minutes. You could alter it for different applications, but this is what they have used for all of their claims. I'm personally a little sceptical that it is as effective as they claim (they did their tests using artificially inocculated material where the spores are only on the outer surface, and they used conidia when there are much more robust spore types oput there). That being said, it may still be a good approach depending on how it affects quality.
As for the pyrimidine dimers, they are just the form of DNA damage that is done from UV radiation. Dont let yourself or any employee be exposed to the UV source and you will be ok (the reason any UV source of this nature is very well labelled and usually encased). It's not like they are created then flow through the air to get you.
UV sterilization usually uses UV-C, which is almost completely filtered by the atmosphere, so they are not really comparable. On that note, if you have something that is claimed to be "UV resistant" or the like, they usually only refer to UV-A and UV-B, so dont trust them if you are working with these systems (make sure your safety equipment is rated for what you are actually working with).

If anyone has street address for any of the producers can you PM me with them. I'm working on a plan to rock the boat at HC.
Thanks for any help
Thanks for any help
Hi Guys, I frequently visited this forum when the new MMPR rules came out because I was checking feasibility if it was possible to start a small legitimate grow business. I have fallen behind now. Has anyone had any luck getting certified by HC? I mean anyone that isnt a giant corporation or in bed with the government in the first place? Thanks all.

No. It's now over a 12 month process.
No small guys are licensed to sell yet. Some may be licensed to grow, but as far as I know there aren't any.
Regulations have changed on the QA front, security front, facility front, etc - it's far more expensive now and you have to have a higher security clearance, better QA availability and higher standards for other random things.
