humidity just wont stay up! im using an ultra sonic humidifer running on a short cycle hydroponics timer dialed to 5 mins on and 5 mins off. the humidity will get up to around 70% when the fogger is on but once it turns off humidity drops down to as low as 20%. and if the exhaust fan is on the humidity will stay very low. i can't leave on the fogger all day because it takes 8.3 amps (about the same as one and a half refrigerators). what should i do, my GH is a lean too with a concrete floor and stucko wall, west facing. would you agree that these conditions are drying it up in there? should i cover the wall with spanish moss and the floor with tuff or something?? should i build a conventional swamp cooler? or just make shure every little crack is sealed in the whole GH?
i tryed it, i had two 0.5 misters spraying for about 5-10 seconds every 5 minutes. it worked ok but water was constantly driping off my balcony and i was worried about wood rotting, maybe if found finer misters? does anybody make a finer mister tip that 0.5 gph, i haven't seen one. or maybe ill just have to make a drainage system.

They do make a finer tip, but I dunno if you need any special equipment to run it. I know at the ATL botanical gardens they have a mist system that pumps out mist so fine it feels dry, but it raises the humidity. It is a super high preassure system. Running a swamp cooler system will help a little, but a freind of mine runns that system and still has a problem with the exhaust fan pulling out the humidity. That is why I am an advicate of pushing air through a swamp cooler I think it pushes in more humidity into the GH and passively pushes it out. I personaly run an exhaust fan, but someone has a GH on the other board I go to that just used a cool master cooler with no exhaust and he is in Arizona. That way your not pulling out the humidity and hs claims it keeps the GH cool enough without pulling it out with an exhaust fan. You can get a fogger for GHs that pump out a good thick fog, but I duno how much they pull as far as amps go. Is the concrete at ground level? You could put mist heads under your benches to spray on the floor and that will increae your humidity too. After watering here during the summer I make sure I finish soaking the floor all the way to help increase humidity that way too.
