1 tbspn of each into a spray bottle, dose em good, fan em down to dry and...wait and watch. Usually can take anywhere from 3-4 doses to get the problem under control.
actually, it will at a high enough shock dosage in an empty room, but that dose would kill your plants if they were in there in about an hour of exposure. it may also kill you, your pets, lol.
in 25 yrs of growing under lights ive never had powdery mildew/boytritis etc...
getting air in and out of the grow room is crucial if you live in an area where powdery mildew exists outside on garden plants ,and moving the air around the grow room is important ,like on a breezy day.
get that humidity down low.
if you keep getting it then use a strain thats resistant.
No the ozone generator will kill the odor that the plants create.
Surfnfisher,
I would suggest to you to create some form of better air circulation in the room by bringing in more fresh air. I don't know how you room is set up so this has to be done independently. Secondly, I would buy a sulfer burner and set it to come on for 30min-1hour one night per week while the lights are off. Make sure you do this after the lights have been off for at least an hour. You want the plant cells to close before the sulfer is released. Additionally, I know you have done so but make sure no mildew is left on any plant. I actually would suggest tossing out any bud and plant that has been in contact with mildew. Mildew can cause serious damage to your lungs or the lungs of your friends.
I dont know, I did a neem 3-1 gardensafe spray yesterday. I will do another in a couple of days. I have lots of air moving and A 747 intake and exhaust on 24/7. I hate neem. I am going try the baking soda next.
I have read so many posts from folks who are claiming to know all about indoor growing and I just have to shake my head at what some people will post as fact. I have been growing indoor hydro for over thirty years long befor a lot of these folks were even born and I just want to post one thing that there seems to be a lot of inexperienced advise being offered about. I have used ozone generators for many different problems in the growroom. Of course smell is the obvious but for killing pests it is a wonder worker also. Before I go any further I know there is without a doubt someone who is just chomping at the bit to post about how ozone will kill your plants and any other negative subjects about ozone that they can think of. I will say that when using ozone in any application other than inline ducting applications that the ozone will kill your plants. I use ozone between every crop and have for years as a sterilizer. I have had virtually every type of bug and disease possible in an indoor grow. You must remove all your plants from the room and throughly clean the room with bleach or a good sterilizer first and then turn on the ozone generator. I run mine for three full days between crops. I have completely eliminated spider mites and powdery mildew from my room and they have never returned by utilizing this method. I will add though, that with powdery mildew I did eliminate all the plants that were infected and started all new plants from seed. As long as you don't bring the fungus back into the room after an ozone sterilization you shouldn't have that problem again. You can really get yourself tied up for a very long time fighting powdery mildew by spraying all these concoctions on your plants and fighting a tuff battle but it is much easier to just get rid of any plants that were in the room during the breakout, sterilizing the room and starting over. That will save you tons of exhausting fighting time not to mention money. Do not enter the room during your ozone application. The bottom line is that ozone in high doses between crops with plants removed will completely clear your room of unwanted issues.
Hydrogen Peroxide will help with powdery as its showing.
Best done when plants are not in the light and 1/2 strength on small plants.
A small amount of a surfactant helps in application
