Buds quality LEDs VS HPS

Again...how did that happen in 2014...or 2012???
I wasn’t happy with the results and prices....so went off and started my own thing.

Still waiting on ANY test here instead of deflections of the presented test. They have been presented for what they are and no attempts or assertions that they are scientific Giselle. Just valid and real test.

But Hey...it’s more fun to deflect and speculate than actially putting the tires to the road and using the horse power. Let me know if ANY other test you people would love t

If you are trying to prove your lights can work as well as hps you have. What else are you getting at?

I got different lab results even from the same lab when the dispensary I used to work with sent in samples from the same oz of weed.

A 2 % variable is always going to happen one way or the other with bud testing.

There is more drastic increases shown from adding uv. Making the lights shown incomplete at best if they are supposed to be better than hps.

Got to love all the talk and ZERO numbers of other test. Only bitching about the one presented.

Get to it people...if it’s so easy and so available and everyone has some...why are NONE presented.

All the ancedotal evidence regarding quality I've seen suggests 400-700nm light is all fairly equal, margin of a few percent. CFL, LED, HPS it's all good.

Back when I was growing I would get 28-32 zips from a 700w output lamp. Over 1.25 GPW of dank from a guy who used a basic fert schedule tap water with micro/bloom and nothing else but PH, 900ppm, and usually was dealing with minor DWC root rot issues the whole time.

That was g5 Vero 18 at nominal current. We're talking maybe 37% efficient on a cold day! It was a large grid of 30w cobs, ran without reflectors. I did even better with a similar rig running g5 Vero29s at 42% efficient. Now 50-60% efficient rigs are available.

Seems like a no brainer to me.

making assumptions about your test is exactly what I am not doing.:bigjoint:
It actually is. And the fact that you don’t see or even know the parameters or the preface of the test, shows very clearly your assumption and lack of any rational thinking on the test. Instead you stay wrongly focused on today, not the test. That is your bias...not mine.

Because My test would also be bias,something I am not afraid to admit Although I have no stake in any kind of lighting or company, I kinda prefer my HID's and my tests from Un biased sources.

Because I didn’t just replace 10kW of lights the year before the test and had some issue that cost us a ton. And when moving into a new space with the new light that they said would fix the issues(lack of PPF) head to head to see what was going on.


Not here to argue with people who won’t step up.
Again...still waiting for anyone else to present some results.

Then why is de hps the industry standard?
For the same reason that we still mine coal. When industries and infrastructure exist around methods, it takes time and money to change.

It takes time and money to do a test, and I suspect the only ones who would be motivated to do it on a big enough scale to be less controversial would be light manufacturers (from either side) who stand to benefit from the results. Edit: making it inherently controversial...

Realistically speaking, who do you think will fund this unbiased larger scale testing, apparently run by an independent contracted facility?

Kinda been my whole point. maybe a university down the road when testing is more legal.

That's what I am trying to get across too. My tests even the nutrient and flushing ones I did in the past with lab results proved very little. So I use what I'm comfortable with and works.

And all the lighting info needed to decide what to buy is available from the universities of Michigan and Utah.

I still find the Grow side by side interesting.

Who said it had to be big?? Many university studies are very small samples/experiments. Good solid methods/practices and documentation are enough. Seriously...looking g for anything at this point

Seriously...I’m looking for anything...anyone to step up and present it.
There is a BML video out there, that no one has used yet that i left for you, hoping someone would at least attempt to present something. But hey, even that is too hard for this thread/forum.

Come on guys...shit or get off the pot. .

No you just won't entertain any conversation about your results for fear they are not as conclusive as you want them to be.

I suspect Inda-Gro did testing before they decided to build LED lights, to know for themselves that the product would produce. Anyone know someone who works there?

The other people who stand to profit and would therefor be motivated to do unbiased testing since their only goal is more efficiency and/or a better product, are large scale cannabis producers. Again, you'd probably have to know someone to get that info shared, but I've seen a bunch of pictures on this website of decent sized commercial grows that converted to LED/COB lighting -- what convinced them? Maybe it was just the electricity savings over time, I really don't know. I do know that if my income depended on the quality of my product, I would do some testing before investing.

Their test is just wrapping up and was a simple grow using all there lights. There is a thread called “20 plant grow” or something like that...should be on the first few pages of this section.
I’m technically a Indagro distributor/seller still. Tested them in 2014 as well and he kick back was I could sell them. Believe Hyroot still is too and has he new fixture.
I have never sold any of their lights or used my indagro discount in anyway. Sent my test fixture to cocokola on here and he disappeared.

They have not sent their fixture to lab testing and have said on their FB page their numbers were calculated from the strip manufacturer they use’s data sheets. Not full system real world test.

wonder what their test results will show, HMM?:roll::mrgreen:

i have used hps since 1979..i have totally switched to leds..why??

and nah..noone likes a guy who plays devils advocate with nothing except nomenclature
to back it up..other than that what you got..
oh yeh an unannecdotal 2% variance in thc
besides it was cute the first 10 posts..now you are just a troll

gg has" something "

..you have..."nowt"

sure everyone would love a pile of tests..but not from indagro
