Powder Mildew

MustangStudFarm · Apr 18, 2016

This is my 1st case of mildew after about 5yrs. I never really gave it much thought because spider mites is more of a problem here.
I had a 1000w in my veg room to keep temps up during winter and I recently replaced it with 2x 400's. My big question is, should I start over with my seeds or can I cure this to where it will not be a problem? I have Eagle 20 coming in the mail. I really planned on just spraying the room and equipment with it. The problem is not in my flower room, just in veg...

I have some new seeds coming in and there were only 2 plants that I will miss, but I can buy another pack of them! Would it be easier to just start from new seeds and let my flower room finish and then clean everything with Eagle 20? I am scared to clone off of anything right now, feel like it is a lost cause!

Been looking at the Bodhi 4/20 promos at GLG!!!

I don't know about the starting over part but dont spend a lot of money on powder mildew spray mix some peroxide with water it works pretty good

jtp92 · Apr 18, 2016

O and spray it on the mildew dont feed it to the plant lol

Light bleach water will kill mildew, mold, fungus, all forms of micro insects. I don't know that I would want PM infected plants in my flower room that has never had PM all the same.

Never use eagle 20, it is poison, when burned it turns to hydrogen cyanide, a very deadly gas. It should NEVER be used on anything for consumption, only ornamental plants. Green cure and neem oil are your best bet , bleach and hydrogen peroxide to clean equipment , if its too late in flower you might just cut off the affected areas and throw them in the trash. All PM weed should be thrown in the trash, never smoked. Here in Colorado PM is serious business I lost my mer crop last year to PM, all in the trash can. I hope you get it under control, PM is not a fun thing to deal with, I had to kill my whole crop and start over, bleach everything clean like mad and I still and fighting it a little bit, I spray green cure/ neem oil during veg and first couple weeks of flower and it seems to work good.

completely anecdoctal but since I started using my 12k mh bulb (maybe the UV-c?), and switched to dichlorvos in early stages of flower I haven't had any issues with PM at all..
and I did a run during the el nino storms in CA, in 100% humidity
also the dichlorvos works very well with mites, and is much safer than miticides

I must have been groggy this morning or something.... I still haven't used anything is a simple sentence lol...

So, I came back inside to look at my Bodhi seedlings and noticed that they had something going on! I just cannot catch a break right now.

cant remember, is your grow room apart from your living area?
if so, I recommend hanging dichlorvos strips during vege and the first month of flower.
replace every three days if you have an outbreak, and replace every week if you don't

Veg and flower are separate but my propagation is indoor... Are these bugs on my seedlings? This is the 1st time that I have had either of the 2 problems.

MustangStudFarm · Apr 19, 2016

I just remembered, we have baby chicks in the same room as the seedlings. They have hay for bedding, maybe the bugs came from there???

probably not. probably just came from the "world"
reason I say that is the bugs we gotta worry about for cannabis are not the ones that are eating your hay.
those look like thrips BTW
fuckers...

this is what they can do.
never had a problem with them personally

I have some old azamax on hand, would that work?

yea just go light on that stuff, I see it burning a LOT of plants.
emulisified neem meal would be better but a pain in the ass to make.
I say go get some dichlorvos strips and combat those AND the mites at the same time, without risking/frying your pistils/leaves.

Neem oil +silica + Aloe (I use the 200x powder- just need a little bit, like a pinhead amount for a quart). I also use serenade. Water plus peroxide (1 part peroxide to three parts water) will help kill the spores, but does not really remove the problem. It can help you nurse a plant through the end of flower as long as you spray effected areas whenever you see it.

The neem silica and aloe mixture really works wonders, and you won't have too chop everything down!

Does the neem oil work as a preventive for powdery mildew or as a solution to it? I've never had to deal with it but am interested in knowing because I imagine it'll come up eventually.

Jimsmut · Apr 21, 2016

It seems to work as both in my experience. I just had a male that got it. Once I sprayed it with the neem silica aloe (two treatments), the PM did not come back, even after I kept the plant in the dark for two weeks. When I see it on a plant, I spray everything up to two or three weeks in flower, and am good to go...

ironically when I got PM, just a basic aloe and silica spray worked, i'm wondering if aloe has some hidden antifungal property to it.
Hmmm
