My air exchange rate is good, my humidity stays between 43 and 45 and temps are 83 day time and 77 night time!!! I have a tower fan on medium speed oscillation covering my 4x4 tent!! Is that enough flow inside? Stated to see it on the leaves closer to where my air is comming in from!!! Im pulling from under my house!! should that air be ok?​

Make sure u have a filter on the intake. U can gett those square filters from home depot for like house ac's and shit. Get the most expesive one u can afford.
They also sell these bug shields with charcoal in them and they go over the end of ur fan or ducting. They come in all sizes from 4in to 10in diameter. I have one of these on my intake and one on the exhaust. Work great

Usually air under the house will be very moist, dank ect... so if possible try to intake air from inside the house

Make sure ur plants are spaced out also and not bunched up so that they get even airflow

if it is powder mildew, this is what you do.......................get a spray bottle, add 90% water and 10% milk. spray them on your leaves that's all you got to do. it won't fuck up your plants, you ain't using chemicals and it does the job quick. latez ​

No the filter will not dry the air but it will catch all the crap and mold spores that are coming from under the house. Never heard of using milk but I use neem oil to keep mildew away and as a pesticide. 100% organic.

well milk and water is also 100% organic. if you've never heard of using milk that's too bad, but it works....look it up. if you are getting powder mildew its because of poor circulation and its not because you need a filter on an intake lol. hey bad2587, it looks like you've got good air circulation........how sure are you that it's powdery mildew. you've got pictures?? check underneath the leaf, if there are black little insects, you've been infiltrated by insects, not by powder mildew.

I have a potable a/c and am wondering how to vent it !! I can keep the unit on the outside of the room taking in air from the garage and I can duct an intake into the tent!! and the exhaust would run all the way outside? If i did that the a./c unit would not be able to run on automatic and always be on !! OR should i cut a hole in the tent and let the unit stick half in half out!!! It would know the temp of the room and be taking in the air from the tent? whats best?​
