Yes that is a good question too.

Well... straightforward as the answer may be I have to say I still find the question perfectly legitimate.
Cheers!
After 13 years of growing, yes, light spectrum makes a difference. This is the whole point of inside growing, environmental control. Light is included.
LED's at this point are capable of putting a lot more energy into a single area than HID's can do.
Good spectrum is good spectrum, but if this good ratio of light can be intensified right up to the limit of the plant's ability to process, growth will be better.
Good spectrum requires multiple light sources at the present level of technology. Red and blue feed chlorophyll very well but chlorophyl tastes bad and does not get anyone high. THC likes a few more wavelengths and all those entourage chemicals use more than chlorophyl also.
A good day outdoors beats anything I have built, but inside the weather is excellent 24/7, 365/year and outgrows the the outdoors 9 out of 10 times.
Finding the max for veg at this time, am using double the budding intensity without bleaching due to balanced light ratio's.
Pictures show the level with and without the CMH supplement, the LED's alone do not provide longwave (800 plus nm) red nor green, both very beneficial for growth.
It is not where the light comes from, but what it is.

Unless you have a partner like I have had a time or three, lol. Like the plants are in special forces, one day it's nice tropical island and the next in the desert, then the arctic. the light could be 9, 10 or even 16 hours depending on how many times he walked past the timer. :S Correction always met with, "don't worry their fine". I guess some people can learn and some shouldn't even watch
Those types have proven to be security risks anyway.Wow, what kind of growth rate are you getting with that?
Have you used more blue LEDs for veg? Thinking of trying them for rooting.
I even wonder if different light frequencies can influence a lot of things including flavor.
Light spectra has influence on flavor (terpenes), but not on CBD concentration, that's controlled by Bd/allele.

i think that a cooler light would produce more THC just look at bud grown under 600w vs 1000w... less watts and the shit is wayyy more frosty... i think maybe someone should grow the same bud, same conditions under 400w 600w 1000w hps/metal halide, 300w led, cfls... compare everything then send out a little piece to get tested of each and see what you end up with for results
your question was CBDs so i dont know. gotta leave this one for the pros

Ok, now were cookin.
Care to elaborate on the effect on terpenes? Or ideas on how one might influence them with light?
I know that they are the first to vaporise off, and CBDs take more heat than THC. Kind of puts the two on opposite ends of the spectrum in regards to medicinal vs pleasure traits.

In those cases it's probably less light intensity and more of a heat issue and probably have a general loss of resin from that.
Off topic but what are you using now from veg to flower, a variety of MH/HPS/LED or only LED?
I'm also curious if there are bulbs for UV supplementation developed yet that distribute UV evenly over a canopy. Last I read you had to sort of spot-place UV lights if you wanted to try that route, and that way it's quite a lot of work to try and set that up in a grow space and constantly move them around.

I'm also sure that the evaporation of the terpenoids has a lot to do with the ratios and types of terpenoids present in the final product. Monoterpenes are the easiest to evaporate, then sesqui-, di-, triterpenoids etc.
Regarding the medicinal and psychotropic effects, the terpenoids also play a big role. This is the best thing I have come across regarding the effects of terpenoids. Definitely a good read.
Terpenoids, ‘minor’ cannabinoids contribute to ‘entourage effect’ of cannabis-based medicines

I'm just finishing up my first grow with my new LED light board. This one does have 5 or 6 UV bulbs that the manufacturer claims help with resin production. I'm harvesting the first plant at the end of this week so I should be able to chip in my 2 cents after I get the buds dried out.
