white powder mildew

Pretty sure that's what this is, what do you think? Since the pics they've been taken out and washed with garden hose/sprayer per the guy at the local grow store in MICH and placed back into garden. From the one pic you can nearly see the entrie flower room. Need to know also, what is a good humidity gage to purchace and ways to control. CO2 is not yet installed, but hopefully within 6-12 mos. The garden is driven by 1000w. Room and light are cooled by ambient temp from the AC,that's it, no fans at all. Also, all plants veg under flourescents.
Before I buy a product, I want to check here, thanks in advance.
Also, please see my pics under cloning issues.

Wow, wicked PM.

Not a single fan? There's part of your problem. You just rinsed them with a garden hose and put them back? Get ready for more PM!

Jesus it looks like its been thru a fuckin blizzard. I think the colas will have mold up the stem, how did it get so bad? Your only hope now is a dehumidifier and sulfur burner. You sure there's a roof on that joint?

And yes i agree more large fans running 24/7.

Get the fans going. Now. Hydrogen Pyroxide and water will kill the PM. Then rinse with water 20 min later. FANS FANS FANS. Where is the exhaust from the 1000w going? Fans fans fans. I speak from personal experience. It will never go away until the plant is dead. All u can do is keep it at bay. I wont sugar coat it, but that is pretty extensive. U should have 3 or 4 fans in that room. A box fan, an oscilating fan on a stand, couple of smalll clip on 6"fans. I have a 3x3x6foot room and I have 3 fans in it with one plant. My other room 4x4x8 same thing. Also I bought hoods and a cool tube so I can direct the hot air from the lights out of the rooms. Good luck bro.

Is someone doing lines off your fan leaves..?? Wow thats a major Powdery Mildew problem..YOu need fans in that room and maybe a spray to kill the powdery mildew or a sulfur burner will kill all that powdery mildew. I used some Zero Tolerance fungicide by Ed ROsenthal that worked well.

So tell us... how do you feel about fans? Lol.

fans and milk....
1 part milk to 9 parts water all the way
up to harvest with no change in outcome.
this is used for the big agricultural grows
and has worked very well for me in past
grows as well

the AC/fan runs 24/7. I got a 20" box fan I can put in tonight.
Understanding that it may spread to others in the flower room, Does this mean the strain is bad or just these two in the flower room?
They're two weeks from harvest, if they make it. There's no powder on the bud or stalks, just the leaves, will the bud be alright if I perscribe the above?

BTW Milovan, is this a spray or a feed: 1part milk: 9 wtaer?

ALL your plants got it, but the infestation is internal, not external. on fruit crops powdery mildew is merely an annoyance, but in dope, its a real problem. adding milk to your plants sound kinda crazy. that shit will turn sour, burn foliage, and grow more mould. two weeks from harvest i would use hydrogen peroxide (food grade not the hair bleach shit, go to a health food store) and ventilate ventilate ventilate. after this harvest youll have to sanitize your growroom and the insides of that air conditioner with bleach.

if you can squeak them to harvest, you can wash the buds in a hydrogen peroxide solution before hanging them to dry, Jorge Cervantes has a video on the subject. this should allow you to dry your crop but i bet you have it come back during curing.

dont spray any fungicides this close to harvest, unless you wanna smoke turpentine or brimstone. tough it out with ventilation ventilation ventilation!

dont bullshit urself. PM gets everywher. U have had it since day 1. U just lost control of it. It's a fungus it exist everywhere and now that temps are getting warmer we will fight this harder. I have had the same issue as u let me show u, this was my last flower a month ago

So u and ur friends will be the only ones smoking the weed. If ther are any plants in the room touching leaves they are infected. U just have to keep it at bey till ur whole harvest is done, and then BLEACH the room. Dont kid urself, everyone will agree. Yes ther is a possibility that u can infect the others with the fan, u have no choice. By more fans ur A/C fan is not enough. I have direct vented hoods and cooltubes, so I can specifically direct that hot moist air outside. I now have spider mites. I bought Lady bugs today to combat it. I sprayed her with a soapy water mix twice and rinsed her, then bought 2000 lady bugs. haha. Mine is 9 days into flower.

Now I will say it. I TOLD U SOOO

To the OP, for instance I have a 10' x 10' sealed grow room and I keep 4 oscillating fans going 24/7 on top of the AC. I hope you dont try and give anyone those buds after harvest. I knew a smoker who smoked moldy buds, ended up getting mold in his lungs and had to get it surgically cut out.

I got to see medical proof on that one, gotta call bullshit on that!

Anyone who has smoked marijuana more than a couple times has most likely inhaled mold spores from marijuana. That may sound alarming, however its important to remember that you are likely to inhale the same or similar mold spores while taking a walk in the park. The most common type of mold, Aspergillus, occurs naturally in almost everything in nature.
Most mold spores will have little effect on people with normal immune systems. If the mold is bad enough to cause problems, effects are usually respiratory breathing problems and flu like symptoms such as coughing, diarrhea and vomiting but can be more severe in people with other health conditions and/or a poor immune systems.


Found this report on cannabis culture. man some peoples children?hahahahaha

i knew a guy who sold buds dosed with pcp, he wound up getting a bullet in his lungs and had to get it surgically cut out too.

Disagree. PM is an external affliction. It is not a plant disease that has bonded to the plant on an internal, cellular level.

A clone from a mother that had PM can be dipped and grown completely clean if given the right environment.

If it were internal, then Jorge's h202 bath wouldn't make any sense because there would still be PM 'inside' the plant. Not true.

Here you go dummy!

Aspergillus is a fungus, the same fungus which can grow on marijuana plants. The fungus's spores are in the air we breathe, however an individual with a weakened immune status may be susceptible to aspergillus infection.
Aspergillosis is a group of diseases which can result from aspergillus infection and includes invasive aspergillosis, ABPA, CPA and aspergilloma. Some asthma patients with very severe asthma may also be sensitised to fungi like aspergillus.

Well it's not the mold itself but the spores from the mold are the problem to worry about. The spores can survive pretty much anything this side of hard radiation. If by chance you have a very weak immune system oryou're immune compromised, when you smoke moldy weed the spores can settle into your lungs and grow large mold balls, which are hard to get rid of and sometimes have to be removed surgically.


sigh::: some peoples offspring

powdery mildew can infect internal structures of a plant, particularly stems, and other internal voids. when powdery mildew gets into raspberries, the hollow center of the canes get filled with the shit, and it NEVER goes away. those roots will always grow new canes infested with powdery mildew. when PM gets inside the plant's structure the plant must be destroyed. Jorge may be able to dip cuttings to prevent transfer from a minor infestation, but when its bad, theres no hope, no treatment and no cure. fortunately most common crops (except raspberries, blackberries, roses and a few other rosacea) lack the internal voids which allow a PM infestation to get inside. Cannabis does have these internal voids sadly, and the buds are very prone to this shit. Powdery mildew can destroy an entire rose plantation fast in rainy weather. thats wh so many rose farms are in dry ass areas where roses dont do as well without extensive help. Powdery Mildew and other moulds can destroy them so fast the desert is safer for your plants.
