How to Fight Powdery Mildew in the Grow Room

If you have battled powdery mildew in the past you know how devastating it can be.

Powdery Mildew is a plant disease that can only be maintained (not cured) with fungicides and other plant washes. If your garden is being taken over by this problem it is likely best to take everything down, sterilize and start over fresh. If this is not an option for you, we can give you a run down on some of the products you might use to fight until the end. We also will cover some tips on grow room treatment with sulfur burning/vaporization.

Jorge Cervantes visited a grow in Southern Oregon and they use actinovate and serenade first 3 weeks of flower and thats it. Also foliar feed using silica raises the PH of the surface of the leaves and PM doesn't go for that either. Use TPS silica and Dyna grow protek. Another source of PM discussed in the video with Jorge is cow.or steer manure needs 1 full year of composting before using it in a grow.

interesting how one expert says it is not systemic but the next says it is.

I have found the Serenade disease control to work very well outdoors. It is so pungent and stinky I'm not sure I would want to do it indoors. Great vid thanks!

Dont you want you split unit ac and filter/exhaust on while burning the sulphur so that it sterilizes the ac and exhausts out the smell?

[Deeleeshush]

Thank you for these new informative vids

[patmerrick]

Can actinovate be used during flower and does it show up in lab tests?

How to get the powdery mildew outta the grow room when it’s empty?

[jackydo]

do these help fight bud rot as well? or botrytis cinerea

Thanks for the vid. Regarding the Green Cure, how long into the bud stage can one spray it on the foilage? Someone told me that WPM is systemic and I should use it to flood my container and root ball. Can you help here, they weren't very specific as to how often, when and at what stage the plant is in. I grow for a card holding patient and I don't want his health in jeopardy. Thanks, I hope you still come back and answer comments.

what are thoughts on washing with a hydrogen peroxide water cure to remove it

[taalinstitute]

I have a few indoor plants and I think they have Powdery mildew, what do I do?

[kylendmonasco]

Please know this is extremely dangerous if it it is not purged on maruajuana. And this can give congenital health deficiencies

[littlebeebs]

Do Actinovate or Serenade leave a residue on the plant that makes it look ugly when you spray it ? I need something for PM on succulents. They have farina on them and I'd prefer them not look hideous cuz it defeats the point of having them . They're all indoor plants . These that have the PM don't have lots of roots yet, so systemic won't be affective YET . But I'll use systemic when they've fully rooted . I have sulfur powder, but I read that it's only preventative. Thank you 🙂

Sulphur? Really!? Oh boy!! Bad stuff!...

[thecloneguyz]

This dude is a rookie if he never even mentions a UVC bulb or what they're

[BeEasyTreeFarmer]

This is bad information. Unless you're doing this to sell product which is still just as bad if not worse.

Spray hydrogen peroxide on your plants works wonders with mold.
