I spray for powder mold, it hits back harder

Whats up everyone? I'm looking forward to hearing from u experienced growers here. I've been battling pm In my flower room (hits hard while flowering) for a while now. Been using green cure to spray. But it seems like it's getting immune or something. It's getting worse. I spray only to come back and find more pm the next day (although spraying does removes the thick stuff). I have humidity from 35%-%50 (varies as AC goes on and off). I have a 50 pint dehu pulling 6 gal a day from the air. Temps are from 77-82 or 83 as I'm trying to make it hard for mold to live (also using 1250 ppm of co2 enrichment so I bumped up the temp). What should I do? I've tried a lot of things. What has worked for u? Thanks a bunch!

trim the effect plant matter , keep the fans going like crazy and try to tie your plants to open them up so u have alot of circulation between the stems/leaves. and keep foliage dry never folair feed.

run a dehumidifier during dark cycle, worked for me.

Ya I prune to allow airflow but don't wanna keep pruning affected leaf because it won't have any leaf left soon, I'd rather spray them. What else has worked for you guys. Sulfer spray in a house, in flower? I am willing to do anything now. I have five 16" fans in a bedroom already and gonna add one more to each tray as there is a huge amount of nug Thanks

sulphur burner on a timer. mine comes on for 15 mins each day during lights out. i fought mildew for years. now it's simply gone. you can unplug it the last few weeks of flowering.

I have a constant cycle in flower and never have bud more than 2 weeks from harvest. I don't believe I can burn sulfer right? Especially not in my house right? Thanks bro's

i burn it in my house. you might not be able to on a perpetual though.

damn. anyone else know about sulfur burns during flower? how late can i burn? and does the mold just dissapear?

your not gunna want to hear this, but your gunna have to tear it down, clean, rebuild, clean, and start over from seed. if PM keeps poppin up in your grow, that means your plants and area is totally infested with PM, including your AC and dehumidifier.

gotta get your exhaust in check too. yes, PM is present in the air everywhere, but with proper vents and circulation, PM is not a problem. this does not mean add a bunch of oscillating fan(they DO help), its all about your intake vent(s) exhaust fan(s) AND where you vent it. venting it outside is best. recylcling the air only makes it worse.

i will always stand by the fact that PM is a 100% enviromental issue.


also be careful where you get cuts from. PM from med dispencerys is very common in CA.

i brought home clones to my uninfected grow and got both pm and the evil spider mites... i learned the hard way to always wash clones!

Natural and easy: Baking soda and water (1:10 ratio respectively). It is alkaline and will kill the powdery mildew. I do not recommend spraying any buds during flowering as it can cause Botrytis. Be careful and avoid the buds. You might need to scrub down and keep the humidity way down especially during flowering. Keep your plants spaced apart. Tight plant spacing + high humidity + poor air circulation = PM. Do not overdo the application as it can affect the PH (raises it). Alternatively or in conjunction you could try 50% water and fat free milk as a spray.

If you sulfer burn for 4 hours while the lights are off every three days for nine days your problem will be gone. I have battled powerdy for a long time and finally got rid of it when i did that but i only was two weeks into flower. It might affect the taste!!!!!!!!!!!!!! Make sure that you have some way pull the sulfer out of the room 1 hour before the lights come on!!!!!!!!!!! The only thing is that your house is going to stink really bad for a week or two but to me it is worth it i hate powerdy.and make sure that you do your veg room also even if you dont see it in there !!!!!!!!!put on clean clothes before you go into your flower room after that so that you dont bring it back in there you can even take a shower just to make sure!!!!!!!

i Havent tested it yet but i believe liquid light will discourage pm as it has a ph of like 10 and it says specifally not to adjust the ph. I dont know why but it doesnt burn the plants. I have had pm before in my current grow but i think it was due to some standing water i didnt see. either way the plants that i used liquid light on did not have pm. maby a coincidence because i am only trying it on a small percentage of my plants.

Ya its a bitch. im gonna prune some infected leaf now. its not on buds though so this is good. so burn sulfer inside during flower really? what about spraying sulfer in there (if there is even a spray)? like on the walls and shit. does sulfer kill the powder or what? i wanna do it in my veg to knock out the couple spots i see every once in a while. is it safe on babies in an ezclone machine? i wanna try everything before i tear down. thanks everyone!!

Pm was bad today (flower of course cause veg I spray strong and knock it out). Gonna spray it down again today. What is the remedy people? Thanks

@fdd2kblk. I know bro but I pull in 1 day and can't right now. After the pull I plan on burning but once again my only problem is my perpetual grow. I always have mature bud (like 2 weeks from harvest). I don't wanna affect my bad ass nug but will have to if it gets out of hand. What the **** pm?! Thanks for your help

yup sulphur burner on timer helped ..

You can use GreenCure google it that what they use for tabacco they spray with greencure 7 days before havert ,, check them out ...

Ya I use green cure but the pm seems immune to it now. Ive been using it for months. After I spray I see even more powder mold, it doesn't get rid of it like it used to. I think I have no choice but to burn in flower after this pull, plants will have 2 weeks to recover before harvest after I burn a couple times. Think this will affect taste and smell bad? Think it's a bad idea? But I can't let mold take over! @fdd2blk, picked up a sulfer burner and some sulfer. u burn 15 minutes, once per dark, every night!? Also, how much sulfer do u use? I am gonna use it when lights go out (in veg) so lemme know! Do u turn ur fans and intake and exhaust out all night? Exactly how do u do it bro. Thanks so much
