irrigation setup advice

[stroja62]

hello all,

i am trying to figure out how to setup an additional mister and i am stumped on what to do.

just a little background, i live in Bermuda which tends to be between 60 and 90% humidity. my "greenhouse" is made of 2 x 4's and fabric shade cloth. i lined the inside with a clear plastic to try to retain humidity but for some reason for most of the day the humidity is between 45 and 60%.

i currently have a misting setup that runs for 8 minutes early morning and then 3 times a day it runs for 1 minute just to assist with humitidy.

a few of the mounted plants and the vanda are ususally bone dry within a couple of hours.

my thought was to set up an additional mister just on the mentioned plants to go off every 2 or 3 hours.
would this be ok? or does anyone have any solutions to retain humidity. i have a fan going at all times which probably doesnt help the humidity but definitely helps avoid fungal issues.

First, Welcome!

I am not sure that you really have a problem... these don't have to be sopping wet all the time. At night the humidity goes up as the temperature goes down (that's the "relative" part of "relative humidity") So they likely experience high humidity during part of the daily cycle.

Welcome s62!
I'm not sure if you need a greehouse in your climate.
Why do you think you need one?

Its more just a way to cover the plants from direct sun and its not so much a greenhouse. I guess its a shade house. Also winters are very windy here.

Doesnt the humitidy need to be somewhat constant?

Most orchids benefit from the variations that nature provides. Humidity naturally varies. When the temperature drops, air can't hold as much moisture (and so the relative humidity rises) When the air is warm, just the opposite, it can hold more moisture so the relative humidity drops. It rains, then it stops raining. Epiphytic orchids have evolved to grow and thrive in that variable world. Where you live, I think that the natural humidity should be quite adequate - water the plants well, then they dry during the day. If it doesn't rain, you can water again in the evening and they have all night to soak up that water.
