how much humidity

[dennis]

is to much i recently transfered half of my plants (warm and more light ) into a different room last nite before i shut everything down the temps were in the high 70's and the humidity was at 80% i do have two puter fans running just above the plants

[Tindomul]

I keep mine in vivariums where humidity is over 80%. So long as they get their daily drying out period, they are fine. But for most of the early part of the day, they are at 90% or above humidity.

I agree with Tin. Mine stay at over 80% during day with 3 hour mistings then dry out overnight with constant fan. I run one fan (enough).

I think you humidity will be excellent for many of those tropical orchids...
the humidity will also aid in growth I think

[Marco]

my humidity is 30% my plants hate me

I know humidity is a great attribute to growing orchids, but I might be wrong, feel free to correct me...but when growing indoors, without an orchidarium and it's kind my indoor humidity is not so high, and I have seen where my plants have "learned" to acclimate to the enviroment. Maybe some have had a slower than normal time getting to that point and showing disappointment by not blooming but one day they will love me for it I fear mold/mildew and prefer to keep my humidity at about 55%.

when mold starts growing on the walls, it may be too much.

The higher it is, the more important air circulation is.

[justatypn]

Air circulation is on a constant but not going to chance it to the point of unwanted coloration on the walls, once it reaches the exterior walls it's damaged 'what's lurking behind your walls'. Another angle would be to much air circulation keeping the humidity lower than what it could possibly be if set at a lower rate of speed. Geez, darned if ya do or darned if ya don't...but they are bloomin' for me...so I guess "I'll be"

Air humidity can't be bad for orchids. You need to increase your air circulation to get rid of mold and your orchids will thrive.

I don't have the space for a dedicated orchid room. So outside of my mini's (in an orchidarium) they just have to learn to adjust. There is no other choice.
