Humidity fluctuation question

[greenpassion]

My Windows do fog up when I have the fan blowing over the pot. They are new replacement windows, and as of yet I haven't had any mold problems, but again, I've only done this 4 to 5 times. I am able to lower the humidity to where I want it by lowering the temp on the stovetop and moving the fan further away. It'll be nice to switch to the cool mist humidifier, but in my experience using them, they don't work nearly as well as this pot and fan set up. I'll need to get a minimum of 2.

My humidity regularly goes above 60% in my house if the heat isn't on and frankly I love it, and so do the plants, and this is not with my humidifier on. I only run that when the heat is on. I don't think daily humidity fluctuations are anything to worry about as it's natural for this to occur outdoors and indoors as the temperature changes. But in general I find that when the humidity drastically reduces during winter both outdoors and due to the heater running, a lot of root tips stop being green and those humidity highs go away for months on end. That's the humidity difference that I resent.

I tend to use HR as the main factor to determine water frequency.

Sorry to burst your bubble, but glass "flowing" is a myth. A long time ago, after the technology superseded "spinning" large disks of glass and then squaring them off, window glass was cast in flat sheets, but the cooling of the melt tended to result in thicker portions and thinner ones. If more exact optics was needed, it was ground and polished. Now, almost all window glass is "float glass", made by pouring the molten glass onto a large bath of molten tin, where it can completely level out before being drawn off the far end of the bath, making it extremely uniform and smooth.

In order for the viscosity of glass to get low enough to flow, it would have to be held in excess of 1000 degrees, and held that way a long time.

I wish my Dad was alive to see that those tuition dollars were well spent.

You will be spending a large amount of money in electricity or gas to keep that water hot on your stove. Be careful.

You know, it's really funny ES, but my hot air furnace doesn't come on when I have just this one burner on my stove going. The warm humid air keeps the temperature really nice. So the electricity from one burner on a stove top versus running a hot-air furnace actually I think works in my favor. Of course this doesn't happen when I'm not home...

I have temp and humidity monitors in each room, and each of them will Read around 60 65% humidity and temps 68., when I have the steaming water on the stove top.

I would also be very afraid of leaving the house with the burner on. I know you say you won't do this, but it only takes once to cause a fire.

I am always very conscientious, especially about my house. It is all I have- my plants and my dogs, and I would never ever jeopardize that, even for my beloved orchids!

Your concern is noted and appreciated, very much.

I try to keep my apartment at 75 degrees, 45-50% humidity. If I remember my thermodynamics correctly, warmer air can hold more water. I think it's probably worth reading about dew point vs. relative humidity to get a feel for what optimal conditions should be for your environment.

Here's a good link that covers the topic:

Thanks Boxter. I finally went out and got a cool air ultra sonic humidifier, and although it puts out a good amount of mist, I'll need at least 2 more for this large room.
