Have 6 1000 watt lights in one room & need to hook some kind of thermostat switch inside the room to the incoming 220 line to my lights to cut the juice off in case my A/C takes a crap & everything burns up. Is there anyone have such a setup out there & would you share that with everyone who may want the answer I am looking for. Thanks for any input.
What your looking for is called a "High Temp Shut Off Contactor".. Your local grow store should be able to get ahold of one for you.. Its a little box that gets wired in between your timer and the socket you have your lights wired too.. When the temp reaches a certain point.. it cuts the power to the circuit automatically and allows for a "cool down" time in most cases. Check the amp rating.. a safe bet is 5amps per 1000w ballast.. so if you are running 6 ballasts.. you may need 2 x 15amp shut offs.. or 1x30 amp... depending on how you have your room wired ;-) Cheers!
You may also want to consider popping a couple of HOt5 flourescents in your room.. (even use them as side lighting or w/e) run them off 120 on a different circiut.. that way if your big lights cut out for 15 mins due to high temp.. it wont stress the shit out of your plants going light to dark repeatedly for who knows how long... I have helped a few guys set this kind of thing up and it works really well!
