white powdery mildew

Hi I have the start of white powdery mildew I think. Anyway I have the black saucers and elevators for my fabric pots. After watering plants I left the run off in the pots so its a white residue.. can I spray it with peroxide and kill it or tea tree oil or mix them with water? I was just gonna...

I've noticed that zerotol has given me 100% success eliminating Powdery Mildew alongside proper environmental control (dehumidification, air conditioning, airflow (fans) and such) and literally before I tried nuke em, plant therapy by lost coast, purecrop1, regalia (This works but is funky...

So a little opening details. This is my first grow. I am 30 days into flower currently. 5 gallon pots 250w super hps in 3x3x6ft tent. The air flow outtake goes outside, passive intake on bottom. Sadly no oscillating fans, but I have 2 stagnant fans directing airflow to carbon filter in tent and...

Hey guys I’ve done everything I can think of to rid my tent of WPM but every time I place a plant in there it contracts the disease. I’ve cleaned the tent with bleach, peroxide, disinfectants, you name it. I’ve even steamed it with a steam cleaner. And some how spores are still there. Every time...

Will an air purifier help clear mold spores? I already had a tower air purifier in my home and just threw it in my tent because from my knowledge the HEPA filter should filter spores right? I’m in week 5 of flower. i trimmed most of the fan leaves because a lot were affected and I sprayed the...

I've been doing Plant Tissue Culture for 6 months now. I feel like making something useful out of my vessels with contamination. What would you think would be good way to make a WPM aerosol? I was thinking just scrap the white fuzzy layer off and put it in spray bottle. Why you may ask? To...

Does anyone know how long spores stick around in a room? I had an entire grow destroyed by powdery mildew 3-4 months ago by PM. I only have one location in my house to grow. And I tried every single remedy suggested, and none worked. I want to try and start up again. So do the spores last...

I’ve had issues with white powdery mildew throughout the grow and have organically treated it up until harvest, there were no visible signs of WPM during harvest but I am finding trace amounts during the trim. Nothing on the buds, just small amounts on some of the leaves and stems. What would...

Looking for suggestions on ventiativen my 15.5x17.5x7.5 grow room that has two doorways and one window. Also I'm trying to do this as inexpensively as I can... Is there an exhaust/intake fan window kit or something along those lines ? My room can get high humidity throughout the day and I've...

Wpm 3 weeks until harvest what will keep it at bay with minimal damage ?

So I just transplanted The SFV OG into hydroton clay pebbles 6/9/16. I've been top feeding 6 times a day while the light is on, it's on a 18/6 on at 6pm and off at 12 pm. The plants themselves don't look to good and I noticed a white powder on the stems and on the leaves themselves. The plants...

I've been through this and other forums and it seems that whenever someone mentioned white spots, the discussion goes to either Spider Mites or White Powdery Mildew. I don't believe it is either of those based on the pics I have seen of each. 1. My white spots are like dust particles, not...
