According to the different environment condition and plants, to make sure the appropriate wiring density, normally, to install 80~120W/m2.
For example: if you use a roll of ZDR-100 heating cable, and decide to install 100W/m2. The distance of cables is 8cm.
How to wiring: becase the both sides of hotbeds are easy to lose heat, so we need to install the cables more closely in both sides of the hotbeds. The joints on the heating should lay outside.
Because of the difference of production batch, the color will have be different but with same good quality, we will send the four colors (green, red, yellow, blue) randonly according to the stock, thank you for your understanding.
We have several types of automatic temperature controller for this cables. The cable should be used with a temperature controller.
