Quantum board owners and experienced growers post your GPWs here

[Mariano Gomes]

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!

I like grams per square foot personally. The problem with g/w is that the less light you use, the higher the number it will be and the lower your bud quality will be. I ran only a 180w PlatinumLED in a 3x3 and easily came in over 1 g/w. There were a couple good buds under the light but everything else was super larfy.

What exactly are you trying to do to push led technology forward / maximize diodes? Collect data?

Yes basically collecting data I will add grams per foot then. Basically collect data and make a standard that we could use for LED lights that directly correlates to yield and efficiency. Because right now we know that burples need 50w per sq foot right which is basically the same wattage needed for HID lights so the only advantages for going burple is lower heat and longer usage hours over HID. But with the advent of cobs and new led tech efficiency has dropped it 35 watts per square foot can yield as much as 50 watts per square foot. Since it can produce more photons. maybe from these 3 data inputs GPW, Grams per sqf, and grams per killowatt hours we can have a clearer picture or standard for LEDS. Oh I am talking about actual watts of the wall. And this standard can be used for all LED lights in the future and cut down on false advertising.

I beleave if you dive into @Growmau5 videos on YouTube a lot of this has been done. Maybe not diode LEDs but COBs are covered, FYI Quantum boards and that style of LED is COB, chip on board.
