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 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.

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.

A recent very fair and equal sbs showed these differences using violet. Not uva but violet. Of course it was implemented differently then GLA but with pretty comparitive spectrums all on, a little different from yours But close (both full spectrum, no gaps, 400-750nm. Up against the ChilLed Growcraft heavy red the results were definitely better then assumed. At a 11-12% higher thc, twice the terps/cannabonoids & popping for cbg/n/d while the white+660 ChilLed did not. W/12 oz. More Yeilded over the 4x4. Same cuts sane mom. And Like you, ChilLed had the bigger x4 plants going in. They also had 70w veg advantage too. So anyone saying violet is BS simply is going by this bunk old science that's been out. Uva+B damage cells (good for healthy rejuvintation but not necessary for increses) while short wave higher energy, more useful in par range and photosynthesis violet stresses with more leniency (used sparingly) and creates the effects they're chasing with uva + B.

I follow and use these lights. Despite what anyone says, they know their spectrums & how to use them. GLA, mad props. I bet you conr in higher in every dept too.

Hybridway2, why do you keep lying? Why don't you stop spamming amare(the company you own Marc...) after you have been banned 3 times from RIU? @sunni @potroast ?

did the results for this test come back to you?

I have some very bad news. It's actually much, much worse than that.

As many of you may know, Australia still has some very harsh pot laws. They are so harsh, that in some cases the authorities can confiscate your home and all your assets. Aussies will know what I'm talking about.

The contact who does the testing – which is all underground over here – was busted with a significant grow and it now looks like he may lose everything. I feel so bad for him. Everything was confiscated: the testing equipment, samples and everything else.

I still have samples from the grow, but I no longer have a way of testing them. The guy who was doing it is also a friend, so I'm a bit depressed about the whole thing. I can't provide much more in detail. I can only wish the guy good luck, and of course everyone around him is now trying to lay low. That's why I haven't been on here in recent weeks.

The whole thing sucks :sad:

so sorry to hear that, would appear Australia is a little behind the times in this respect. Best wishes for your pal.
Good that you still have samples, which one do you prefer? I just did an internet search and found some home test kits. Not as good as a lab but its something?

We all preferred the plant grown under the GLA light but I guess you'd expect that. There is no chance of getting the samples tested by the origal guy now, so unless I find someone else local who can do it I will just have to hang on to the sample. The problem is, the longer the samples are held the more they decarboxylate into CBD, so it's hard to get a true reading if you leave it too long. We have done other tests with UVA, so we know what to expect, but that's not the same as actual testing.

what sort of setup was he caught with and how did the measure it all commercial or not?

I can't go into too much detail, but he "allegedly" had enough plants to lose everything he owns. He is also looking at a few years inside. Even with a good lawyer, he is facing some very stiff penalties. That should give you an idea of the "alleged" scale.
