Hey I'm a bit confused about the balance. Are you saying that you could have a perfectly good LED configuration and then add some more red light or blue light and reduce your yields because of the balance even though you have even more wattage? What is the preferred Blue to Red? I know that str8outtaweed's WEX-C150 has like 20% blues while the ones at your site has 40% blues. Why wouldn't simply supplementing blues work?

Also what is the difference between more expensive LED sets and cheaper ones if 660nm is 660nm and 1 watt diode is a 1 watt diode and a 120 degree beam is... you know what I mean.
