I know this was a joke and all but i grow using hps/mh and LED and tbh my cheap ass blurple lights blow my 400w away on frostyness and is pretty much the same on denseness
HPS is crap. The frostiest trees are surrounded by LED's.

UV is pointless to bother with, every try here led to not a thing. I appreciate the science but it never came about in practice of all the growers that have ever tried it.
I feel the subjects redundant indoors and very few longer growers bother with it.

Frostiest, smelliest trees are grown outside...and they don't melt when burnt..

I gotta say! "Trying" isn't a bad choice.
I will say that those little LED's. Won't supply any light intensity that will actually effect the outcome...overall.
I'll also say that you have the supplement's that are doing it for you - terp, trich and therefor "oil" increase....

i guess i will have to learn my lesson, lol. i just added 2-25w T5 bulbs to my 4x4 tent this grow.
i will be honest, at first, the lights 2 feet away were too close and i could see the plants suffering. i was also running the lights 15 mins every hour for 7 hours.
i pulled the lights up almost 3' above the canopy and only run 15 mins every hour for 4 hours now. the buds are most definitely frostier. whether that makes for a stronger smoke or not, i will not know for another month or so.
UV can be damaging, that's for sure

UV-B is what you want. The easiest way I've found is in reptile bulbs they are cheap and readily available that being said they are not intended for a multi-light HIGH production environment, there are dedicated lights for that purpose but for a tent they can be used in my experience. Just be careful and turn them off before you enter the garden UV-B Kills humans.

Yes that is the goal we were all working to before leds started making wild claims about light.
Full spectrum trumps all, its why cmh is so good at its job and where leds failed to outyeild hps. A photon is a photon at the end of the day

right! read on here one day a guy said led lighting causes a calcium deficiency. ROFLMAO Really! well i guess that the photon produced by leds is magically different than photons of different light sources.Yes that is the goal we were all working to before leds started making wild claims about light.

Actually, different lights are stronger in certain spectrums and different spectrums are responsible for the production of different compounds within the plant. So yes, different lights can change how a plant grows, which in turn can create higher or lower demand for particular nutrient.

interesting theory nano but i disagree. i hope im wrong and it would be awesome if you could post a link to a study confirming that, it would mean i learnt something and if i learn something so do 1000s of others with all the people i educate in my shop. this is what i know.... blue photons carry more energy than red photons. uv photons are damaging to cells causing the plant to produce more oil to protect its self. theoretically the plant would need more nutes to mane the oil but in no uv plant study do i remember any mention of a different nutrient requirements, no do i remember anyone saying they put in uv and it causing a deficiency. i know that red and far red work together in the plant and makes the whole greater than the sum of its parts. this is known as the Emerson effect. we know it takes a couple hours for the photocrome red to turn into photocrome far red after the lights go out. we know that if a far red light is run for 15-30 min after lights out this speeds up putting the plant to sleep. green light dosnt wake a plant up like other specrtiums do however, some studies show green light is related to a plants drought resistance but that thoes studies haven't shown to be definitive (even if this proves to be true who cares about drought in an indoor garden lol.

"his experiment has provided additional
evidence that equal PPF does not necessarily
result in equivalent amount of mineral uptake.
Spectral quality may exert an influence on
mineral nutrition through related physiolog-
ical processes such as stomatal control, trans-
piration and carbohydrate translocation."
Quick excerpt from the pdf if you don't feel loke reading the whole thing. They've known since the 60s that spectral quality effects nutrient uptake. They do close the article by saying that ultimately you are better off making up for abundance or deficiency by altering your feed schedule than you are trying to use supplimental light to balance the problems that result. Or, better yet, use full spectrum light.

leds can provide some spectrum that hps just cannot.
there are are even led systems that put out the spectrums that the sun provides at the exact hours of the day those spectrums are being produced. hps can't do that.
with that said i use both led and hps
