Wow Jandre, I'm stunned at the difference! I mean, I'm always happy when i see LED performing CLOSE to HID. I've never seen LED surpass HID like this before! At least part of that could be due to how much detailed tuning you put into determining the correct light distance. I've heard other LED users indicate that growth can slow greatly if this isn't adjusted just right.
Most of the head-to-head comparisons between LED and HID I've seen (especially on Youtube) are so incompetent due to HID users not grasping many important factors that are different with LEDs and just stringing them up and using them exactly the same way they're using the HIDs. And then saying: "look how much smaller the LED buds are! LEDs suck!
I saw one that was so mismatched that it was ridiculous. The guy was using 600w HID against a "300w" LED. As we know, that "300w" LED was probably actually drawing 200w or less. So yeah, it didn't produce the same yeild as the 600w...
Anyway, I'm glad to see you doing it right and the results, so far, are really exciting for this LED enthusiast!
