Trichomes, THC and UVB light.....

Maybe what we need is a comprehensive light metering station in the location known for the highest potency pot, and do a full cycle growth recording of the conditions measuring photoperiod, spectrum, intensity, angle of incidence, etc. do that for 3-5 repititions and come up with some data. or maybe someone did that already....and I should just go back to growing my plants? hahahahahaha:blsmoke:
lol
that is very interesting though
I watched that weed man video and he was sayng that all the best weed comes from the equator areas
those get the most red spectrum light than the rest of the globe

all joking aside....it would be interesting. The challenging part is standardizing the circumstances to ensure that you are truly undestanding the nature of all the variables. As a practicing scientist....this is a big step.....and making sure you have all your assumptions adequately identified and understood. But...it could be very instructive.....

The are 2 libraries which have the answer. U of Maryland and Michigan.

The effects of ultraviolet-B radiation on the growth, physiology and cannabinoid production of Cannabis sativa L.

hey YGF...yea this is the paper that I continue to search for....

Lydon, J., A. H. Teramura and C. B. Coffman (1987) UV-B radiation effects on photosynthesis, growth and cannabinoid production of two Cannabis sativa chemotypes. Photochem. Photobiol. 46, 201-206.

cheers man!

Well that is where the only 2 copies _ other than what the author has _ exist. I've searched the databases and this is it. Nothing more, nothing less.

I've got an email off to the good Dr., but who knows if/when I'll get a response.

You could petition your local university to purchase a copy.

thanks man. that might just be the thing to do...i found a bunch of other stuff again tonight....I'll forward to you.... :hump:

Well I have just started exposing some stunted flowering plants to 365nm UV along with a 250watt Eurolite Sodium/MH they are on 12/12 at present, and I will keep it up until death or harvest.

hey man....that'll be interesting - please keep us updated on your observations....and thanks for taking this on. I believe the references I have seen specify that the uv light is most effective in the uvb range (280-320nm) - as this is where the biochemical interactions were most responsive. the light you are using is uva light (i.e., 320-400nm) and has not demonstrated the same results in previous tests.

How did you arrive at 365 nano meteres wavelength? Got any pic's??

It's what it says on the bulb mate. I am also now full time (24/24) using an actinic moonlight bulb in my clone area to supplement the CFL. no ill effects as yet, indeed the plants are growing straight and true, correcting a bias toward the CFL. the bulb is designed to aid photosynthesis (in marine plants).

The plants will/should lean towards the more intense/luminous light source. If the lights are either side and of equal luminosity then that should hold the plant in a steady central position.

Cannabis loves light.

In these UVB tests... does anyone know how they were conducted? Like were the UV lights added as an extra light source, or with the lumens taken into account and levelled off so that the plants would be receiving the same amount?

We know that lumens are responsible for everything the plant does (even if it is a lack of them)... so maybe in these tests it was simply the added lumens that added to the potency.

I had heard many years ago about using facial tanners hanging from cords with the lights coming on for 20 minutes every hour with the lamps hung 8" further away from the ideal facial tanning distance stated in the manual.

Marijuana man also recently verbalized his ideas and theories that the best weed always comes from the countries that have the highest uvb exposure.

I have never heard of any proper scientific tests and in all reality as you said it is also possible that it is just the extra lumens that give better bud as weed is very light responsive and for all we really know it might be the soil or the air in these countries with a higher uvb level that makes better weed.

However having said that it does seem very logical that the plants would produce more of their natural defense chemicals which we just happen to love to smoke.
Hopefully in response to thinking they may get sunburn they may produce more suntan cream:mrgreen:

You and I are on the exact same page. I can tell you that _ at altitude, >7,000' _ plants have to be carefully conditioned prior to full exposure to sunlight. It is my belief the plant produces 'X' amount of THC, as is _ without any supplemental uv. Then when UV is added either by man or nature, the plant produces more sunscreen to protect itself.

*This is my opinion and I'm probably wrong.

In Ed's first book, he expounded about how plants have their environment encoded into their DNA and if one was going to be successful at growing, you had to, as best as possible, replicate the environment it was used to growing in.

Okay, hang with me, I've got a good buzz and am thinking clearly.... we _ as people _ are similar to plants in many ways. We need water, light, nutes. We get injured and repair ourselves, etc. Over time, our ancestors who resided at/near the equatorial areas had their skin develop darker pigment because of exposure to the sun/uv. This is a fact.

Therefore, it also stands to reason that plants grown in these areas are more potent because of their exposure to the same conditions. Sun/uv.

We have _ over the last 30 years become quite proficient in replicating a number of the key elements to successfully grow indoors.... I still believe the absolute best weed I've ever smoked consistently comes from outdoors, and quite a few had seeds. I digress.... we have lights that go far beyond my original 'Power-Twist' floro's, we have nutes, PPM meters. But we don't have much uv.

So, this rant is about the Darwin-ism of the plant. If we expose the White Widow, Super Silver Haze, and other premium indoor strained to constant uv, at levels which had not been present before.....Will the plant, like us, develop dark skin _ more THC?

Yeah man know yourself know everything else(a bit anyway):blsmoke:

I like to think that one of the best growing secrets is to tell the plant that you will help it to evolve.
In my case as i always pollinate at least 10 seeds on every plant this is true.

I provide a shit environment and shit grow products and i get good stuff all though i do have a growing method and it does help i think that directing my will power towards plants does work.

I like to believe not that i am talking to the plants as i might talk to you but just that i give off an aura of truth in the reality that i did create this weed and that i am further procreating the weed for future generations and that somehow and maybe the plants know that i am helping them just as plants and flowers knew that they needed insects to pollinate them and then adapted to attract insects like bees etc.

I am hoping that they keep doing well for me because they want to attract me like a bee to look after them and pollinate them and i have communicated what i want by constantly directing my needs and what i will do for them in return so that they will evolve further to become more of what we want.

Now all i have to do is get it to work on humans:mrgreen:

What a very interesting concept - 10 seeds from every plant. I like it and it can't hurt. Plus, todays seeds are tomorrow's Acapulco Gold or maybe Panama Red.

I'm ready to accept that plants 'know'. To what extent I'm not sure, but I am sure they do 'know'. Have you ever known a plant to go to seed overnight, right after you walked thru and said....Tomorrow is the day? I'm real superstitious.

Ive never known of a plant that you could tell to go to seed:mrgreen:

When i say communicate i mean i think about my needs from the plant and i direct it mentally with my minds voice at them every day.
I have no idea if this really works or if i am just to stoned.:joint:

But you all have to admit that the plants must have some kind of idea of their surroundings and what creatures they need around them in order to survive and procreate:blsmoke:
