Hey guys I haven't posted in a long time I have just been wondering how to increase the humidity in an indoor greenhouse to about 80%. I researched a bunch of sites saying about gravel in a tray method, others say misting. What would you guys think is the best method to get the humidity around 80%?

i think that misting will quickly increase humidity TEMPORALY but to maintain 80% humidity you would need pebble trays,possible a few depending on size of enclosure, and also plant should be enclosed, also more plants will bring humidity up!!
others might confirm this, you may not need to enclose it im often wrong

well......as sawchuck says....misting is only a temporary way to get the humidity up. I know a lot of greenhouses which use the gravel in tray method which seems to work well....basically you want a shallow tray....coarse "substrate" and then water in the tray.....that means higher surface area = higher evaporation.

Is the kind of gravel you find in playgrounds ok? It seems a little small

i use fishtank gravel the colourfull kind , i think your trying to get as much surface arae as possible so dont submerge the stones or gravel completely, and keep them at this level for constant humidity

I'd use the clay pebble stones. They're about 3/8 of an inch in diameter. Orchid growers use them to keep humidity up around their plants. The orchid pots sit on top of the pebbles and the water level is kept just below the top of the pebbles so the orchid pot is not sitting in water. As the water evaporates...voila, humidity around your plant. In Edmonton, I picked some up at All Seasons Garden Centre and have also seen them at Rona Hardware in the Garden section. You can also try Home Depot's garden section, or any fine greenhouse.

Along those lines, I have a N. Alata I've been trying to find humidity for, I just took this pic with a humidity of 41%, this is a high, it goes down to 25% humidity too. Less than putting it in a green house, any suggestions to raise the humidity?? I've tried a bag over it but started to get black spots on it so I took it off... Or... should I just keep my pants un-knotted and leave it the way it is and deal with it as it climatizes? I've had it for 4 weeks now...

It looks like mine, stopped all pitchers in the dry winter. I'm hoping it will pitcher as the humidity increases. Mine came in the same size pot and I just repotted as it dried out too fast.

umm.. one thing Rug does for his indoor green house is have a rubbermaid type container long and wide enough to cover the bottom of the green house and then keep it full of water.
For terrariums, get some egg crate, cut it big enough to cover the bottom, then suspend it a little and keep the bottom full of water. Works good for me in a 55 gal one.
Other then that, I'm unsure...

im having a real problem with humidity in my mini-greenhouse, it camps at 40%rh. i have a huge rubber maid bin at the bottom with water in it and another with all my plants and pebbles. when you guys are refering to "pebble trays" should i just get a couple shallow trays and put water/stones in them w/o plants say if i put 4 or 5 pebble trays in w/o plants how much would i exect to see my humidty increase hacker posted a kind of home made humidifier in another post and i couldnt get it to even budge my rh EDIT:i found this site if i made 4 trays liek that and put them on the self below my plants ( the shelfs are a wire grid) would that be good? www.dutchgrowers.ca/IG_pebbletray.html

In my terrariums, i just put 1 inch of water in the bottom of the aquarium. i use rock wool for hydroponics and i sit the nepenthes on it.That way the plants are sucking water from the wool so they never go dry.and i put a plexiglass with holes in it for aeration and getting more light from the neons. My nepenthes and my Bromeliad Reducta like's it alot. I never tested humidity in there but there is condensation on the windows so i think it is good for them

Rymah, is your greenhouse sealed ? If it is ,the humidity should stay inside.
