So I was thinking of starting a thread for grams per watt (and if you want to be more accurate include grams per kilowatt hours for your whole grow op) on quantum boards or whichever led products that use the samsung diodes since quantum is just a brand and a lot of people are coming up their own board. I guess list down the strain, boards used plus drivers, grow space size/tent size, growing medium plus size, and training methods. Feel free to add additional stats that might be needed. This couldd be a sticky for these samsung diode boards. My intention for this thread is to push led technology forward as we seek how to maximize these diodes. Thank you!
