Clean Powdery Mildew After Harvest?

Hello I read that its very difficult to get rid of powdery mildew - yesterday I was checking some leaves on plants in their 8 week of flowering and found some pm, luckily very few, small white spots on leaves (in 7 from 10 plants) and a little in just one small bud. So I'm not so worried about the harvest cause I'm flushing anyway - and in a week or so I will cut them down so it will not get enough time to spread before the cut... but I would like to know; where I don't see any spot its ok to smoke without concerns or can be still there some powdery or spores even when the buds dried? (Should I submerge the buds in Hydrogen peroxide? or just the the places with white spots should be removed and in my case it would be only some leaves).

And how difficult is to totally clean the pm from the indoor; walls, fans, pots etc, its enough if I spray them with rubbing alcohol and wait for one day to put again another plants? (new from seeds)

thank you

I've never done it, but this might help. H2O2 Wash.

hi thank you, my doubt about doing the bath if it is really necessary? in my case I will remove all the material with pm (the leaves cause all the buds are clean), in the video he is explaining how to clean a material which is completely infected so in the video the buds had pm.

20 grams of sodium bicarbonate per gallon of water, spray on infected areas sparingly but completely.

Do you have pics and are you sure they're ready? No need to flush.

So you want the person to spray baking soda on a plant....

I guess he can let it spread to the buds during the dark, dry process. Rather have a minute amount of sodium bicarbonate on the plant then be smoking live spores of Golovinomyces cichoracearum. Really don't care what he does, one way or the other.

Potassium bicarbonate is better than baking soda. But I wouldn't really want to spray anything on my plants in late flower either way. Especially indoors. But that's me.

Normally I would completely agree with you, but in this case, since it is a live fungus, it should be addressed before the plants are placed in the dark to dry, which will allow the Golovinomyces cichoracearum to spread rapidly, as they will be saturated in moisture, as they asperate the remaining moisture and die.

is this an alternative to the hydrogen peroxide? cause I have seen that you can use either but in that case i prefer to spray HP (10ml per liter of water) and you should rinse afterwards anyway.

I don't have pics, for legal issues I prefer not to take - but I know for sure that they are ready - about the flush I know there is a lot of discussion if its necessary or not, based on my experience it make the smoke smoother so one week before harvest I water them with citric acid (Grotek final flush)

If you don't see helicopters flying over you house or strange vehicles in front of your house you should be OK, lol.

Just delete the metadata if you're worried unless you're outside where us cops can get your location still thanks to stuff like Google Earth.

I seriously doubt it's ready, but I'm only guessing without pics.

h202 will kill it on contact, but won't kill the spores (in my experience) then 2 minutes later that same area will be able to start all over. Sodium bicarbonate will kill it, the spores and keep the area sprayed protected from it coming back. Sodium bicarbonate is not going to hurt the plant or you. You can't taste it, smell it or even see it if you follow my ratio. I use sodium bicarbonate when I cook muffins, birthday cakes, pretty much anything I want to rise in the oven.

Is he gonna bake his plants? This is getting funny man. I know you can use baking soda for WPM, but I think there's better options.

Let the plants rise, lol.

You know how to pull moisture out so it won't happen during drying......baking soda....then rinse with h2o2, then dry with a fan..along with the baking soda, in a box or use a small bowl

I have a hard time believing the baking soda lowering RH much. Ya, I know it will a little, but I seriously doubt it would do anything with my area. Maybe a tiny enclosed box, sure. I mean I keep it in the fridge for absorbing moisture as well as any smells.

When I had to run a dehumidifier I would have about a gallon of water to drain everyday. It would take a shitload of baking soda to get rid of that amount of moisture.

Tiny enclosed box....hmmm 2x2 tent, 3x3, 4x4......

And you keep it in the fridge for what?

Larger spaces will need a dehumidifier, smaller ones no.....
