My DIY Heating Mat. 35$

I have read in the "bible" that it stimulates root growth for cuttings to keep the rockwool wamer then the ambient temp. I am going to give it a shot. Here is how I did it:

I made a rectanglular box to fit under my humidome

Then, map out where your parts will be installed

I cut-in my dimmer switch boxes, and used dimmers to controll the intensity of the light. For heat controll.

I like the creativity man! The only thing is that it doesn't very practical when you can buy one that isn't a fire hazard, is specifically designed for the application, uses less electricity, and is cheaper to buy. Here's a link:http://htgsupply.com/viewproduct.asp?productID=51504 Not trying to burst your bubble or anything but when it is easier, safer, and probably better to just buy what you know works that's what you should do. Don't reinvent the wheel dude... Good luck

Now, screw down all parts, and run wire.

I used 14/2 S.O. chord you can get from home depot/lowes. About 15' is good.
I also picked up a male chord end to make my own socket insert.

That pretty cool. Thx for the site. Guess I can just line this with some CFL's then

i used to have a heated propogator, i read the same thing as you, it helps root growth blah blah, i could never figure out why my clones never rooted though, then i switched the heated prop off and they took every time.....
