first time out,C. Vegged for 2-3 months,i know longer then i need but light situation is the hold up. I am concerned about heat and energy,although getting the most for my money and best yeild possible is my main concern,and im trying to to do the best research for my conditions as i can.You see,i can spend $100 more and get a 1000w opposed to 600w,and this is where my problem lies.From the way it looks everyone is definitely in favor of the 600w instead of the 1000w.

Let's throw everything out the window thats been said and speak in theoretical terms. You have 2 5x6x8 room's. Exact same setup in each to the T! Same amount of plants and genetics,they grow exactly the same, same setup,same humidity and temp in the room,etc etc etc(im aware this is not realistic as nothing in nature is identical,but theoretically speaking..... One room has a 600w,the other has a 1000w.They grow for the same amount of time. Which room is going to produce a better yeild and why? Rember the only thing different in the equation is the light,everything identical
