Those are some sweet bins. Since we got the LER for the CXA2700K, it seems that the 2700K Z2 bin is about equal with the 3000K Z4 bin when you factor in the increase in photosynthetic efficiency. They would make a great pair.
Few hours back I downloaded the datasheet for the 3070 3000k, I see that there is a new (highest) bin for the 3000K: AB that gives 8500-9130 lumens. The Z4 gives 2% less lumens less at 25C than in a older datasheet, now 7945-8534 lumen.Still the 3000K Z4 is a wild chip !
A single type of led array(COB ) ,that can grow almost anything !
Wild !
I think we can attribute the anthocyanins present to the green light the CXA emits. Even under the 2700k 3050 I had a completely purple stems and buds Edit: on my Blueberry Gum. It is a wonder how the CXAs bring out the true nature of these plantsThe 3000K COBs have only 10% blue, but even that causes the anthocyanins to come out in almost every plant. I assume the plant keys on 450nm blue to infer the presence of UVA and UVB so they protect themselves with antioxidants.
Hmmm, very interesting. I'll have to keep that in mind. Still trying to track down sandpaper finer than 400 and a palm sander cheaper than $40.Definitely a result of the LEDs. I never got that kind of color with the HPS. Even the 3000K COBs with only 10% blue cause the anthocyanins to come out. I assume the 450nm blue causes the plants to assume there is UVA and UVB so they protect themselves with antioxidants.
I use this Diamond Sharping stone to lap my heat sinks. Has two grits Medium 400 and a fine 600. Works really well for a lot of things and wont wear out like sand paper. http://www.ebay.com/itm/New-Duck-2-x-6-Diamond-Sharpening-Stone-Knife-Scissors-Tools-Sharpener-/380908323073?pt=US_Knives_Tools&hash=item58afe7c101Hmmm, very interesting.
