IMHO you should start losing the dome first then removing the heat mat maybe a couple of days later. And if your lights are more than a few inches away from your current seedlings then you can lower it to boost warmth for seeds and seedlings alike. The cold room temps will affect your unsprouted seeds more than the sprouted ones. Or you could always move your seedlings into other containers and leave the stubborn seeds on the heat mat.

IF you don't use it I would totally disable the features for it in your windows live. I don't use the IM features or any of that stuff in my hotmail so it is all disabled and I do not take any requests period.

I guess I didn't give enough info. I was using the install disc and was trying to install an optional program called "Natural Color Pro" from the disc. As soon as I clicked on install it came up in Firefox. That was why i wanted to turn FF off, After i read the screen closely there was a workaround that I got to work. Everything is now working great, all I have to do now ti to learn how to use it. Thanks again.....Jim

Nevermind. Got it direct from Pentair. In case anyone else ever needs to know, you have to follow the power cord to the bottom of the power box and disconnect by unscrewing the handscrew that holds the cord on. No tools needed. It was simple. There IS NO on/off switch.
