No THC in HID indoor gardens?

[Levitikuz]

What do you think of that? Everyone growing with just HID lights produce little to no THC in there weed? check this out and tell me what you think...

UVB light is the only light that will produce THC in marijuana?....

 

[SweetIndica2]

Sounds like a controversial subject, i don't think it's 100% correct though. A bunch of well known breeders have tested the THC in certain strains, and i've seen some pretty high numbers. Granted, i'm sure not all of them are 100% truthful...but most of these breeders are using HID's, as most growers do.

I have been growing with HID's for years, and have never noticed a decrease in potency as opposed to weed that around a few decades ago, infact IMO todays weed can be higher quality simply due to the information, and technology that is available for growing. Nowerdays you can practically fine tune a plant, to give it the best potency and yield, etc. possible.

never watched it; dont need to. the proof is, as they say, in the pudding, and i've got a few jars of pudding stored in a cool, dark place.

This has got to be a joke.

 

[Levitikuz]

Listen im not sayin 1 way or another...but you do get high off of the CBDs and CBNs also...so if you had bud with just CBDs and CBNs your still gonna get high...watch the video and learn some things...im not saying what this guy is claiming is true...but he does teach you some things about how the plant creates the thc...and the proof in the pudding...well that pudding may just have cbds and cbns with little to no thc...(IM NOT SAYIN ITS TRUE NOR DO I BELIEVE IT)
I just think maybe we should research this little topic...
because it is true that we have no UVB light in a all HID garden..
But UVB light has definitly been a part of the earth system forever..and plants have obiviously adapted to use UVB lighting..



If i had a big enough place with the time needed i would definitly do a side by side grow and see what results i came up with...
(I think somone needs to)

There be pudding all over the place, ARRRRRRRRR!!!!!!!!!

 

[NiteTiger]

There has been some speculation on the use of UV lighting to enhance bud production, but I haven't seen anything definitive.

However, CBN and CBD are Degraded THC from what I understand, so you can't have one without the other.

Does the video have a lab comparison between an indoor same strain sample grown without UVB, and one with? If they don't, it's a moot point anyway.

Misterpostman uses UVB i think...........makes sense that it would make

a difference........

This guy is taking a theory thats been around some time and making a lot of assumptions.He lost me totally when he said the function of the trichrome is to protect seed.Has he ever grown I wonder?My blockhead develops trichromes long before mating season if you know what I mean.I doubt this stoner could finish a joint of my inside UVB starved erb.

"Now, scientists don't know everything about this process."

im glad he said that early on. as far as the cherry bomb example, i believe he said it was 2 different growers(im sure with differing styles) so ima throw that out.
I personally think it is total BS because, as said the pudding is out there

now the way i belive it to be is clear is CBD, cloudy is THC, and amber is CBN..........i dont know if this is right but i THINK i heard somewhere a while ago.
anyway, overall i think the message is clear;

so many grow books to tell you how to grow a better leaf, but there needs to be more on how to grow better/more calyxes.

also, he needs to reference the science hes using to come up with this(said right after he sparks one up) so we can read it ourselves.

True that

Im saying that plants use UV light for somthing...and maybe MJ uses it to make more THC...Humans even use UVB light!!! So plants definitly use it for somthing...It part of the light spectrum!! I personally think there is some big questions that we all ignore for some reason and make jokes about it...but the fact of the matter is that UVB light has been shining on plants for millions of years and are HID lights for only about 25 or so...i know for a fact plants use this light spectrum for many different puposes...so yes i think UVB light may help produce alot more THC in your bud...and if i had a damn labrotory to test the percentages i would! but most people cant prove shit like that because we dont have the right equipment necesarry...so until you get Lab test back on your "pudding" stop saying its proof...

This video is old news.....like months and months old. Regardless, the author "Marijuana Man" has many very valid findings that might explain how UVB light contributes to higher THC content. It does not, however, prove that there is no THC production if UVB is absent either. Which invalidates the claim that "there is zero THC production w/HID only light."

The point that is most important here is that it seems that UVB light may actually have a very large impact on THC production, which interests me.....does it interest you? I thought so

So of course like you, I ran out and searched for the UVB light of my dreams, but found only ones that are measured in percentages like 10% or 20%, how do you convert that so that it is in the range found in the below scale of 610 - 720 nm??

This chart was shamelessly stole from a site who stole it from a site who stole it from a site......u get the idea.
How the Sunlight Effects cannabis plant Growth

200 - 280 nm UVC ultraviolet range which is extremely harmful to cannabis plants because it is highly toxic.
280 - 315 nm Includes harmful UVB ultraviolet light which causes cannabis plants colors to fade.
315 - 380 nm Range of UVA ultraviolet light which is neither harmful nor beneficial to cannabis plant growth.
380 - 400 nm Start of visible light spectrum. Process of chlorophyll absorption begins. UV protected plastics ideally block out any light below this range.
400 - 520 nm This range includes violet, blue, and green bands. Peak absorption by chlorophyll occurs, and a strong influence on photosynthesis. (promotes vegetative growth)
520 - 610 nm This range includes the green, yellow, and orange bands and has less absorption by pigments.
610 - 720 nm This is the red band. Large amount of absorption by chlorophyll occurs, and most significant influence on photosynthesis. (promotes flowering and budding)
720 - 1000 nm There is little absorption by chlorophyll here. Flowering and germination is influenced. At the high end of the band is infrared, which is heat.

A good site for getting a grip on UVB lighting here

As much good information as there is there, I still cannot determine what type of UVB bulb to buy so that I am in the correct range of 610-720 nm for flowering.

Any ideas?

did someone say puddin

I have a large UV light that was used in a plating shop back in the 80's. It closed down and I got to keep it. It says when used you have to wear protective cream and gloves. I was thinking of using this light to supliment a crop as it is much more powerful than a reptile light and should be able to produce enough light along side a 1000 watt HPS. I don't know where you would purchase one of these lights, but it's the largest UV producing light I have ever seen. On the label somewhere it has warnings and also a chart showing the spectrum. I have not seen the light in a few years as it is stored at my fathers. I will get it and post some pictures and show the chart that I believe has the nm reading. Would be perfect for a side by side grow to see if anything good comes of it.

What a bag of hot air. Now it's my turn to let out some steam...
This person is spreading heresay and wasting 17 minutes of our time. When it comes to the ending, you find out the guy doesn't even grow and hasn't really done the research on a solution. This is just HIS random theory on why he thinks he used to get more stoned "back in the day".

The utter lack of experience is what stands out the most.

#1 Places like Alaska and Australia grow some of the best pot in the world. The major difference you're going to see in your smoke is from the water/fertilizers being used. Other than that, as long as conditions are optimal, the plant will push out as much resin as it's genetically programmed to.

#2 His statements about why the plant creates THC is only a personal theory. In my opinion, it doesn't make much sense. If THC is designed as a "master defense" then he's obviously never grown outdoors (where he'd soon learn that cannabis seems to be the most attractive plant for anything out in the wild to munch on).

It could also be possible that the plants which produced more THC were naturally attractive for their pungent aromas and juicy flowers. I find it interesting that the plant pushes out the most resin when the seeds reach full maturity. Animals munching on these delicious flower would allow for further cannabis propagation into other areas. Has anyone ever seen insects become immobilized from coming into contact with THC (I WISH).

It could also be possible that selectively breeding a plant for medicinal purposes for over 5,000 years has caused the plant to exaggerate some minute mutation in the plant's chemistry.

#3 His attempts to impress you with big words like 'terpenes' and 'phenols' are another way to highlight his laziness and ignorance. He could have avoided that part all together, since he obviously has no grasp on plant biology, therefore it gave us no further insight into the process of creation.

What I'm truly afraid of is his target audience: Literally tens of thousands of teenage pot smokers who aspire to grow and will ultimately be IC members someday. Can you imagine the foundation of misinformation they will come in with after this?

I've read entire research papers on why it's scientifically impossible for your pets to get high because animals don't have the specific cannibinoid receptors that humans do. You don't even have to smoke with your pets to test this, just leave a bit of hash out on the counter and see what happens ("Dammit Sue!")

NORML still has an official policy about bongs being the least efficient smoking device. It is my opinion after many years of smoking, that there is no better delivery than a water-cooled bong hit. Vaporizers have there place, but bongs for the head!

I'd say the most challenging part of being an experienced grower on this forum must be dealing with the waves of passionately naive freshman growers.

sounds very interesting TGT...i would love to see a side by side grow then have a smoke report done to compare...
