Ok so there is a lot of different info about Mildew and I am trying to piece together some info on Powdery Mildew. Lets say a room has a bad infestation and you are going to shut it down and start over with fresh clones from an uninfected source. As far as how to clean I see people say just "bleach" everything, well that is too general an answer for me, so to get more specific.
The challenge is killing the asexual spores called conidia. These are the white "mildew" that is seen. PM also has sexual spores that it releases when it gets cold and it thinks winter is approaching. I think these are called cleistotheca and are little brown sap looking things on leaves that look like thrip turds. The conidia I read can live up to 21 days, the Cleistotheca live months. I think if you have mildew it is better to up the cold nights so that u only have conidia to fight against. These conida are asexual spores that need to live on another plant. They are obligate parasites. In nature they might get blown by the wind into atmosphere when conditions good and land far away and start to grow. In a room they might land on walls or any surface like edges of tables, under tables etc. I have yet to find out if conidia or cleistos can rest in medium and grow onto root for example. But so the spores are on the walls. How to kill them? You can turn off everything for 3 weeks which hopefully the spores will have died. But u do not want to have everything down that long so how can we accelerate this shut down? I think the variables and products might include Sulfur Burners, Ozone Gnerators, high temps and maybe other stuff too.
Lets say you clear everything out on Sunday, day zero, 0. Then on Monday you add Physan20 which is like bleach in that it contains Clorine type compounds and is known to be very good for disinfecting. Add that to the ebb n flow resevoirs and run them a bunch to do initial disinfection.
* SULFUR BURNER. Day 1 Run this for hours, perhaps at least 8 hours long. This releases elemental sulfur which is at ph8 I think. I read that it binds to hydrogen atoms in spores but I am not sure of the nature of this on resting spores. I know it stops spores from germinating on living tissue but does it kill spores that are resting? I imagine it might at some concentration kill off the spores. Anybody have any info on using sulfur this way? Does it disinfect in addition to stopping spore germination?
* OZONE GENERATOR Day 2 Ozone is a very reactive form of oxygen. It is often used to cover up smells and sometimes used for disinfectiong. I think you could crank it up in the room with fans off for hours then vent it. While it is in contact with spores it might rip them up and destroy them. Is this a good way to disinfect? Anybody have experience with this?
* HIGH HEAT. Day 3 I suppose any easy thing to do after those two treatments on day 3 is to turn on all lights and turn off ventilation so room gets very warm like over 110 but below 130. This could really torture spores as well. This kind of thing could be used in any room shut down as hi heat increases metabloism and might stress organism.
My goal is to annihilate the room during this shut down with lots of corrosive compounds that r in a from (mists) that allow them to coat every surface. This is better than I could every hope to do by hand.
Do any of u have any experience with these shut downs? Any rules of thumbs? What do you think of the regimen of compunds? Are there side effects? Like I think that rubber might eventually get damaged by ozone.
I hope we get some good answers here, I have read alot about PM and will continue to learn but I think this a enormous problem that alot of people deal with improperly. I think alot of people confuse control (sulfur burner, PM will return after stop using sulfer ) for eradication (permanently gone). My goal is ERADICATION.
With no plants alive in room and I hit the walls hard with these compunds I am thinking a few days of shut down. 3 days? 7 days? what does everybody think?
MUST ERADICATE THE BORG NANOBOTS!
