Here's a question for any one who has checked and an idea for anyone interested. Is there more CBD produced from an LED or a HPS. And is the difference, if any, related to increase of resin or increase or decrease in it or another cannabinoid?

I don't see why there would be a difference.
What makes you think there would?

[jamminman]

I have heard that UV-b produces more THC from CBD, so if light can affect it than....? I have experienced more oil produced from LEDs, so again...reason to wonder for inquiring minds.

i think that genetics has more to do with CBD and THC production than the type of light source used.

however instead of "LED vs. HPS" maybe a better question would be "sunlight vs. artificial light"

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.

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.
