Spectrum question

[jaywillin]

3500k vs 3000k 380nm-780nm
I am very familiar with 3500k, I have 3 autocobs, I'm just trying to get a better understanding of 3000k 380nm-780nm
which is boosted red ? more geared towards flowering ? do the plants need anything different under the 3000k lights ?
thanks

3k is more geared towards flowering 4-3500 is good for both. 3500 being used most in home grows seeing it’s in the middle.

3k can be used for veg too just might get a little stretchier with more internodal spacing.

thanks guys,
good to hear about the possibility of stretching, compact, shorter plants are better suited for my space
I was just kinda curious about the 3000k, no real desire to venture away from 3500k.
the only decision I've been going back and forth on is getting another couple of autocobs for my 2x3
or trying a qb type light , I've already got a pretty good short list, it's just pulling the damn trigger !

Although can't go wrong with either, I suggest stick with AutoCOBs vs. QBs. I've seen multiple comments from owners of both that say the QBs work great, comparable, etc. but not better than the AutoCOBs.

2 in the 2x3 would do nicely that's for sure

I suggest... If want the latest and most up-to-date technical knowledge of what the Cannabis and hemp plant actually needs in the photon of full Spectrum Lighting...from far blue and far red outside of PAR.
One needs to study Dr. Bruce Bugbee of Utah State University and the CEO of Apogee Industries ( a maker of photon light density meters).

Dr. Bruce Bugbee has been teaching plant biology and science at Utah State University 43 years and has been funded by NASA for 33 years.
Utah State University is one of the few College/ Universities in the United States that is license to study cannabis and hemp.
He and teams of scientist AR doing thousands of tests around the world on cannabis and hemp (NOW) and he has hundreds of other scientists grads & undergrads performing test daily right now.

You can look him up on YouTube and watch hours and hours of classes and Technical information on the subject you are seeking info on....of far blue and far red photons and what the effects have a upon cannabis in real time.
As these test are the most relevant and latest information on cannabis that you can find....And has changed the thinking of PAR and what it means to the cannabis plant.

I discovered Dr Bruce bugbee about 10 months ago. And his test and input has revolutionized the way I grow. And I don't play. If it ain't relevant and if it ain't working... I ain't using it. And would be considered bunk in my opinion...
I only use the best and I only run the best and I grow 99.9% organically. To grow AAA bud .

So I suggest y'all get on the stick and start studying... because all good Growers study

before they grow and make up your own decisions like I did...
And you can grow like I do . Or maybe even better. Know before you grow...it's the best thing you can ever do.

When they come out with LED lights and chips that have the far Red Spectrum and the far blue Spectrum I will use LED lights as well as they have to be affordable and that would make them cost-effective... The red LED chips are super expensive...Those ones that you see on that 315 CMH light with the 4000k bulb.

3k can be used for veg too just might get a little stretchier with more internodal spacing.

For 16 of those 20" inch far red LED chips strips... was a 425.00 bucks shipped to the house from eBay.
The far-red technology is very expensive right now. But those far red LED strips are in the range from. 660 to 780 nm.
So from studying the tests and conclusive Photon usage of the cannabis plant. The green Spectrum the far Red Spectrum is utilized in the growth and flower throughout the entire grow. The Sun delivers all of the full spectrum and that's why cannabis plant's do so well Outdoors. In the Full Sun...

In order to simulate the sun with artificial light one has to use all of the spectrum from the far blue to the far red and everything in between. And you will have the.
Thoroughbred of all artificial lights. Like a finely-tuned NASCAR it's a winner every time.

Enough said figure it out for yourselves fellas...

One must also take into account CO2 levels if growing indoors with high PAR full spectrum lights. The more photons the more CO2 needed for photosynthesis. Kinda like an air fuel ratio for a engine. Too lean she will overheat and burn up too much she will bog down stall.

Yes you have to have all your ducks in a row oxygen CO2 wind water light nutrients they all have to be in the line to grow super weed.
That's why I told them to study. And they all can figure that all out for themselves.
Study study study. To gro like a pro...

I was just thinking about that, wondering if maybe that was s

thanks for this, I had wondered about CO2 before and a quick read here, it looks like I could benefit
lots of other great stuff too, I do have some minor horticulture experience, but nothing weed specific
and I'm only on my 4th, grow, indoors, in a tent, with lights, trying to do it cheap, lol,
first three grows all had issues, nothing major, learning experiences, this ones going better
and still learning, and having fun
thanks again for the info
