Best Powder Mildew preventative?

I live in a swampy area. It's inevitable that I will end up getting some spores in the grow room. I have added a HEPA filtration system that is equipped with a UV light. I change my clothes before entering. I have been reading about all of the different products out there including milk as a foiler spray to prevent powdery mildew. I am just curious to see what everybody is doing to keep PM at bay. I also have a dehumidifier in my room and I am trying to keep the humidity below 50%, but I know that always doesn't work. I have a few different sprays, Regalia, Ed's zero tolerance. But I'm also looking into Procidic2. I saw that people were using eagle 20 but I've read a bunch of stuff that says that is not good to use since it not good to inhale. I can't use a sulfur burner because the grow is in my house in a spare bedroom. Any information from you experience growers that have had PM and have dealt with it I would appreciate the help and the knowledge!

My 2 acres of property includes 1/2 acre of wetlands (aka swamp) and across the street is acres and acres of wetlands. I have never had WPM in my tent *knock on wood* even though I've had high humidity in there from time to time. Good air circulation through the tent, and good air circulation in the tent, are both very important. I also never do any type of foliar spraying so that could also be why I haven't had any issue with it in my tent. I've never used any preventative sprays for it, either.

Southern ag garden friendly fungicide seems to be keeping it at bay. I had it last run and my clones got a couple spots that keep popping up. I've been foliar spraying and watering with silica too.

@Renfro any suggestions here for PM where OP can't necessarily use Sulphur?

Get enough air flow inside your space, avoid temp swings during your lights on/off, clean up and cut all your undergrowth that doesnt receive light, and change your clothes before entering your grow room. Showering is even better before going in.
Spraying plants indoors is a PIA.

That looks pretty sweet. But how much does that bad dog cost?

I've got plenty of airflow. I will keep my temperatures day and night as close as I can this run. Normally I do rinse off in the shower before I go in now just because I've had it before. I even went in the room like a Jedi with the sani light from california light works.

I do admit I did foilar spray with photosynthesis plus a few times In veg. But this time I won't. The results were just so awesome! Never seen a plant pray so hard!

I never had it for 18yrs until I had to move my plants to someone's house that let the humidity get too high with barely any airflow. Tons of air flow and humidity control has always been enough for me.

If you are seriously interested then PM me the info on your space, how many cubic feet is the volume of your room? I assume it's a flowering room. I will get you a quote. Will need your zip code to calculate the shipping.

This is just a spare room with a 4x8 tent. But I do have a bigger setup other than my home grow. But at this time funds are tapped. Once things get better and I can recover from this last lost crop I will get in contact. Thank you for the reply!

Think I'm gonna just start over after this run and get an ozone generator to run in the room.

Well just some information about the product. It will take care of your odor and will sterilize all surfaces in your room (plants included). Leaves no residue and is safe for you and your plants.

I picked up some Regalia By Marrone Bio Innovations. After doing some research I decided to give a try. I drenched my media and gave them a nice spray top and bottom tonight. Last week I used some Einstiens Oil. I will be sticking with the venerate every week. Building up the plants natural defense to pathogens. Hopefully it works out this crop. So far everything looks beautiful!

And it works like a champ. I had a friend bring over a plant that had PM on a few lower leaves, I put it in a room (not my grow room lol) with the AirROS unit for an hour and then put the AirROS back in my grow room. The PM on the plant died and the plant is healthy and I gave it back to my homey.

@Renfro Thanks Man I’ll read up on them. I’ve been reading about 30 topics on dehumidifiers. Saw this for sale today. I’d have it in a very well insulated Garage. It’s 576ft2 Your opinion On them? I agree with one post someone made said that most of the 30 50 70 pint Lowes Menards dehumidifiers aren’t built to last though I’m sure some people get lucky and use one for five years plus.
