At the end of week 10 I harvested all plants. I cut off all big fan-leaves and all other leaves that are bigger than my thumbnail and then cut the whole plant at the stem and hang them as a whole upside down in my tent. After 2 weeks of drying I try to bend a side-branch and if it breaks with a hearable sound, the buds are dry enough to put them into glass-pots for curing. After trimming the dried buds I put the two sides separately on the scale. One main cola of the LUMATEK side (=left side in tent) had bud-rot and had to be thrown out (=appr. 20 gram). The rest of the left side harvested 862 grams of dried buds. Divide the total (=882 gram) by the 600 Watt of power used by the ZEUS 600W PRO, the LUMATEK side yielded 1,47 GRAM PER WATT for this cycle. The right side with the two SANlight Q6W-Gen.2 lamps used 460 Watts of power (=including the dimming) and harvested 880 gram of dried bud, that is an EXCELLENT YIELD OF 1,91 GRAM PER WATT. Therefore I conclude my comparative LED-grow with a CLEAR VICTORY for the SANlight LEDs over LUMATEK! 👍😎 The SANlight achieved 0,44 GRAM PER WATT MORE THAN the Lumatek!
