Not too long from now I will be purchasing or building my own rack system. Im just really confused about one thing. I know how to connect the clips and wires to the flex watt and all of that. But what I dont understand is exactly how the probe will be able to connect to every flex watt.

I will be purchasing/building a rack system will belly heat. So if I have a rack with multiple rows like this one, and have have a separate flex watt for each row how would that work with only one probe?

I understand that if I purchase a thermostat like this one it comes with a 6 plug outlet strip to connect each flex watt cord to, but I still dont understand how is that going to work with only one probe.

The only way it seems like Id be able to make it work is if I purchased something like the hydrofarm thermostat without a probe, and connect a 6 plug outlet strip to it, after Ive already plugged in each flex watt cord to the strip.

Can someone try to explain this to me? Sorry if its hard to understand, I tried to explain it as clearly as possible.
Thank you
