1000 Watt (x2) Heat issue

Hi there 1st post here...

I have a 10'x10' room that I have grown 6-9 plants in the past with one of the aforementioned HPS lights. I am planning on doubling my production by adding an additional 1000 watt HPS..

I already have a carbon filtered can fan in the room and didnt have any heat issues in the past; and i never ran the ventilation/ducting through the lights.

My question is, is this imperative to do? If I have two lights in the room will I need to run the ducting through the lights to avoid any heat issues?

Thanks in advance for the help, I certainly appreciate it!

I'm running into a similar problem in a slightly smaller room, having the light on obvously increases the heat quite a bit, so running two lights would make it even hotter I imagine. As long as your temps aren't running hotter than 80F you should be alright. I hooked up a small inline booster fan to the vent on my hood with a 400w HPS, and it cut the temps in my 4x4x7 tent by 2-3 degrees, venting out the hot air within the room is as critical as bringing the proper temperature air from outside, so maybe you want to try hooking up a booster fan or something? Good luck and happy growing!

I'm ok with my temps getting up to 86, but no higher than that. As long as there is good ventilation and always a fan on your plants you'll be ok.

Last winter (I live in western Minnesota) I had a problem with the temps (basement/cellar) getting too low <65 with lights off; hence I put an electric space heater in the room and that helped nicely! Gonna trying an Ebb and Grow soon and see how that goes with the rez temps and all...
