I go back and forth on the LEDs. I have a 6 - 8 week window before I can build my room so I have plenty of time to read. What I'm missing in my research are LED grow logs from more than just a few people. I'd love to go this route as it would ease numerous issues but they are hard to commit to given the scant success stories.

One resource that might interest others is this little calculator that compares electricity savings using an LED vs. 600w HPS. Pretty impressive numbers. Now this thing is calibrated for tomatoes etc. so I'm not saying this is the product to use. Far from it. And before anyone flames me, I'm not saying that this could replace a 600w HPS with the same results. Please. But it is a nice little tool to gauge cost savings.
