I think you misunderstood what I wrote. I am obviously biased towards my own lights, but the grow-off was not. If that were the case, we would have put the bigger clone under our light intead of the Mars Hydro – you can see it for yourself in the photos.The comparison was obviously biased towards your own lights (I know you said this). As for the stretching and uneven canopy under the Mars, do you think the grower maybe didn’t care for them as much? Even subconsciously?
They end product looks identical to me.
I also don't see any way the grower could have favoured one over the other cosidering they were both the same clone, they were both fed from the same reservoir with the same nutrients, temps, humidity and airflow, and both were in the same tent with a partition down the middle.
Perhaps the photos look identical to you, but they didn't look identical in real life and you can even see some of the photos I posted showing the Mars plants stretching more than the GLA. This was reflected in the bud structure, also.
As I said right from the start, the fact we were involved in this trial even on the periphery (by providing the lights and light readings) is going to lead to expectations of bias – I get that. But I would suggest if you look through what I have posted, I have tried to be as fair as possible. You might also expect that if we were going to slant this trial in our favour or post up results that were embelished, then we would have had our lighting winning by a much larger margin than it did.
There is a very good reason – which many don't understand – why a lower CCT fixture can prevent stretch compared to a higher CCT fixture. The secret is the UV, which is responsible for cell contraction but, because it is dim to the human eye, does not influence the Kelvin rating as much as other spectra that are brighter and contribute more to the overall colours we (with human eyes) see. It is the same at the other end of the spectrum, in the far red and infra red ranges. Adding far red diodes does not change the CCT as much as adding red, green or blue diodes. CCT is just a number – if you look at the spectral range of high CRI vs low CRI LEDs in the same Kelvin rating, you will see what I mean.
So that part of the experiment did not surprise us.
Here is the plankian locus – do you see how the lines converge? Anywhere along each of these lines is the same CCT. However, the further you get away from the black locus line, the lower the CRI. You can see that a 3000K light can have very different spectral properties depending on whether it is biased towards the violet/blue or green/yellow ends of the spectrum.
