    Default 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?

    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.

    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!
