I am currently running 2- 400w lights, one metal halide and one hps. My room is a sealed 10x10 approximately. It stays around 80 deg and humidity is just right. I am thinking about going with the bigger lights. My question is....will the 1000 watt lights make the room so hot that i have to air condition it and put in a bunch of ducts and fans? Is it worth the faster and heavier yields of the 1000w setup?

Yes......you will need to ventilate or cool.

To be honest, I dont know how your room is 80 deg as is with the 2 400's going, I was running 1 at one time in a 5x5 room and the temps were in upper 90s, with the AC cranking. The 1000w (if you have the budget for the extra equipment and electric costs) is definitely worth it.... more lumens/sqft which results in higher yields. But it comes at a cost $$ etc... you will DEF need ducts/fans, I dont reccommend running a 1000w unless its aircooled or in a humongous room with good air flow. That being said, if you have 2 lights, they will cover more surface area of plants, a 1000w wont cover the same amount of sqft... so production may just even out.... In my experience the 400s have been enough for me... Im afraid to turn my 1000watter on... that thing is an energy thirsty beast

Yes - its worth the upgrade - but 2x600s might be better - and yes you will need to vent them.
