Most of them I have to water on Saturdays. Some like the oncidiums, I have to water every 5 days. I have almost all of them in leca/moss and bark mix.

Thanks for info, Steve.
This is good to know as I heard how great ultrasonic type. I don't think it is for me.

Do you have hard water in your area? I have so many plants and I love misting them. I would be spending some serious money buying water :rofl:

I have hard water. If I will start misting, do I have to use distilled water? Does misting work for your chids?

Humidity is something that really concerned me about growing orchids, but I have found that orchids (at least the ones I grow) do just fine (not perfectly fine) without humidifiers. Then again, I'm in Northeast, not Texas where humidity is probably much lower.

With that said, I do use a whole room humidifier with one gallon size tank for winter. It has desired humidity level settings of 60% down to 40%, although I don't think it really means much other than output level as I do not see any feature on the machine itself nor on the user manual mentioning anything about the machine being able to sense its surrounding humidity level and adjust to it.

By the way, I use a humidifier for me not for plants. I feel I breathe more comfortable with humidifier around when the air can be so dry in the winter. I guess that could also mean having humidifier helps out my plants a little bit if any.

Even with a humidifier on, plants seem really dry ( hence I question how much having humidifier helps with orchids) all the time, so I mist plants heavily in the morning hoping at least while water from misting evaporates, the humidity will go up some.

The relative humidity in my room is usually aroun 40-70 depending on the season.

If your orchids grow and flower in your condition, I don't think you need to worry much about adding humidity. Proper watering is much more important unless your humidity level is extremely low and plants suffer because of that.

Should this be moved to the windowsill thread? We're really trying to get that thread it's own section and this info would really help our cause!

As for the humidifiers, yes our humidity with doing everything we can to keep it up has been hovering around 30% this past week due to the really cold weather. The furnace seems to be running non-stop, the humidity is down, our throats are raw and our skin is dry. We have two humidifiers running on high full time, they're the evaporative ones I find the cool/warm mist ones leave a film all over everything. The evap ones don't seem to do this. And yes we're using the same water. Which is hard. By the orchids I have humidity trays and mist them every morning. I normally mist with tap water, but switched to rain/snow water to help keep down the deposits on the leaves. I also open the dishwasher after doing the dishes which releases a lot of moisture as well. Normal winter weather, when it's not 4 degrees out, the humidity stays around 40% in the summer it can get as high as 90% so we run an air conditioner on dehumidify which brings it back down to about 60%.

Like NYCorchidman said about running a humidifier for himself not the plants, with your low levels it's better for YOUR personal health to raise it a bit. People do best around 35% or higher. It helps hair, skin and noses and throats.

In the winter time I disconnect the dryer hose and put a pantyhose sock on the end of the hose as a lint trap. I hang the hose so its a couple of feet off the ground. This gives me and my plants lots of extra heat and humidity that I would otherwise be blowing outside. Just some food for thought. Works well with my setup.

Oh, my, I've never thought of that! :lol:

This kinda makes me wish I had a dryer..

This is an update to this humidifier for my windowsill orchids thread. I purchased the Vornado Humidifier
Evap3 from Costco. I set it up at 50% and low fan and it raises the humidity from 55-65%. I have been replacing the 1.5 gal every 2 days and I have been letting water sit for 2 days before I put it in yhe humidifier. My Oncidium Wildcat Golden Red is about to bloom and other phals with flower spikes that are about to bloom. I am thinking of not purchasing the humidifier for the whole house for now due to the expense.
