Damnm..that bad out there huh? My cousin had a bush outside covered in mites almost all year long. It would be COVERED with webs and all in the middle of summer. She would do all she could with the room to kill them bastards and sure as shit they would pop back up about every 3 or 4 weeks like clockwork. They were getting in somehow (it dont take much). She pulled the bush up and out the front yard....mites never came back in the room.
One thing I haven't seen, nor want to see are spidermites. PM is bad though, you must be humid like here, we have year round humidity, rotting/mouldy leaves and melting snow, perfect breeding ground for PM in the spring.
I have a hard time getting my RH above 20%. I have a swamp cooler I might use at some point, but I don't like that idea at all, I'd rather have low RH than high. I'm confused though, @since1991 do you have any idea why you had worse PM problems in lower RH?
Those are a similar tech but meant to be installed inline with your HVAC intake so air passes by them as its sucking air into the furnace/air conditioner. They might work if you could fit and power one inside your intake vent. Might be worth trying to maguiver it into your intake. Only problem I see with something like this is it's blowing the scrubbed air into your room which is good, but it's not scrubbing the air inside your room. Not sure how effective it would be.
I have no furnace/ ac, just my ducting, from the outside to the garage and the garage out, is this a decent setup for that?
If your only source of fresh air is outdoor air (which has been established can suck in PM since you have PM outdoor), then you might be better off with a carbon filter on the incoming air and some form of scrubber inside the room. Or a furnace filter or the like on the intake and an air filtration unit inside the room. You could try one of those UV inline units before or after some form of filter on the intake.
This is Colorado; even in summer you can pull air in from outside at night and know it will be cool enough. And as for RH, the only time it climbs past 50% is when it's actually raining.
When I first started growing indoor I thought it would be a no brainer, I had no clue how important it would be to maintain the right environment. My large outdoor grows were well north of where I live now and PM wasn't an issue there. Once I went through the first 6 months I trashed everything including my (naïve) thinking on the environment and built a proper room, including the effort/time to tie into my HVAC for air. At that point I took an oath to either do it right or not bother, whatever it takes to maintain the environment at whatever cost. Within reason of some return but at less than $1.00/gram I can afford to run extra equipment if that's what it takes to maintain the environment. If I hadn't been able to tie into my HVAC I would have put in a mini-split.
I have the same massive pile of detritus left over from 'upgrades', although in my case it really IS about finding a better way to grow indoors.
Whoa, brother- them's some big shoes you're fitting me out for!
Yep, I was one of those coming in from outdoor thinking I knew everything when in fact I knew shit in retrospect. I did do a ton of reading and picked up some invaluable tips, but still did some dumb ass stuff because although I listen, I do tend to try things for myself, even if I know there's risk of failure. I still have that pile of things that didn't work but most of any extra equipment around is from trying new stuff. I get bored easy, and I pay for it, but that's Ok, it's a hobby which I love doing and more than pays for itself, not many hobbies like that around
