@JUNGLE_B4RNS, thank you. As far as I understand that means also your actual yield/W was 1.6g, was it not? For me, getting the most yield out of a give space is critical. Therefore I am wondering if you have any experience about the yield of a 680W Mars Hyro LED at 100%. Or if you can give a approximation what you would expect in a 4'x4'tent that would be highly appreciated from me.

@JUNGLE_B4RNS,thank you for explaining. I am thinking about changing from HID to LED. I just have a test run with 600W in a 4'x4' tent. Did you do a whole run at 100%? I think it would be more yield. What do you think?

Great report, thank you. Why do you run the lights on 50% only?

Awesome work dude, would you mind to upload a picture of the defoliated plants in week 9? Do you think the defoliating increases yield or quality?
