sorry , i;m just an old indoor dirt farmer who quite using sol 25 years ago. most of my outdoor grows "disappeared"before they were fully ripe.Now I grow what ya'll call "budcicles" 12' to 18' colas that seem to ripen equally their entire length .

Take care, Sal.

ok i 'm pretty sure i think i might understand what your saying.you what me to reread the PAD and than hang the inc's so their light is evenly distributed on the plants entire length ? I was considering using 200watt inc's hung above.

Science Nerds Unit!

I think of spectrums for plant growth in terms of two spectral ranges of phytochrome reception, but really it's three. I tend to think of Red and Blue behaviorly as one factor and the Far Red 700nm to 800nm as another factor.

When using PAD, tight volumetric uniformity results in a tight genetic (mRNA) responce ranges (reduced genetic bandwidth).

As a specialist and a well practiced researcher I'm sure I'm much more bandwidth critical than most.

In one respect this is like most growing, you get better results the next time arround by learning how to dial into your plants demands and responces to the environment you provide to the plant.

I hate sounding qualitative all the time, but I'm really just here to your perspectives and desires.


- I'm on those graphs next time, thanks Dog.

Take care, Sal.

Hell most of us, myself included don't even know what genetic bandwidth is...LOL.. Although I think I'm starting to understand it a little more each time you talk about it.... :thumbsup:

Fact: McCree did not publish his first experimental results since they did not meet is expectations, and he then modified his experimental proceedure to include a baseline using a background continuum spectrum and measuring the results of additive bands of light.

Also: McCree uses 25nm bandwidths in his work, where TP's (Rauber's) work uses 5nm bands just as the CIE Chromaticity and Lumen standards do.

What McCree left out of his work is the spandard responce of adding additional units of background spectrum and observing the results.

What the data tells me (with different references than most), is that Red gives too much of a responce and low end Blue does not give enough compared to the expected responce of a chlorophyl saturated leaf, which approaches a blackbody on trend, negating it's responce curve to a flat line from arround 400nm to 700nm roughly.

So what is the responce we see, if not the photosynthetic responce of chlorophyl (which is actually the doppler affects of a Hydrogen Ion degeneracy pumped through an organic molecular system anyway)?

Find the line were the spectrum ballances phytochrome to your liking and you then have a competely new set of Relative data references.

That's me dancing arround what I can't dump from Rauber's patent yet, but it's more conceptually than I can stear you guys towards.

Take Care, Sal.

Ok, I thought that I was getting a good grip on this. :jawdropper:

Can I use UVB 5.0 lighting from germ too flowering. I have been using a UVB 5.0 20w lamp for about a week now.I am new to this so please be easy on me. :D Here are some pictures of my first grow; this is a picture at day 5-6! :thumbsup:

This may be a tad off topic at this point, but thought I'd mention it anyway...

I've seen this show on TV last night. Called something like "Should I Get High?" (It's kinda like that Super-Size Me guy that ate McDonalds for a month to monitor the effects) Anyway, the lady hadn't smoked cannabis before, and went to Amsterdam to document her experiences, and the effects of smoking for a month straight on her psychological make-up. Would she go schizophrenic after one joint like the European media was saying?

Anyway, near the end of the show the subject is in a lab being injected with a pure THC. In another test, she is injected with a THC with cannibinoids. (I don't think they mentioned which cannibinoid(s).

In the first test with pure THC, she was freaking-out a tad and was getting paranoid and showed definate signs of unease.
In the second test, she was all giggly and playful...couldn't stop laughing. Simplistic, but was only an hour show.

Having smoked this shit daily for decades...maybe I'm crazy, but it makes sense that the physical effects of THC can be altered by dicking with the THC:CBN:CBD ratios. (if indeed these are the cannabinoids refered to in the show)

Perhaps different strains deal with the damaging UV rays at different speeds, and likely at different times during the grow. Depending on initial (baseline without interference) ratios to begin with, effects might or might not be 'kicked-up a notch' by using UV lighting. Perhaps some strains start-out degrading the CBD's earlier/later than other's. Perhaps some strains have less CBD to be degraded, to begin with. (I might be backwards on this CBD:CBN degradation thing)

Also, does every strain come with a different ratio of cannabinoids, or can we alter this through either light or chemistry...?

And then there's this: Cannabis and Cannabinoids

IDK...Guess it's time for morning coffee. :jointsmile:

Great questions rusty.. I hope sal can shed some light on your questions..

Aloha RT,

"Also, does every strain come with a different ratio of cannabinoids, or can we alter this through either light or chemistry...?"

I'd guess, yes, and yes.:D

CBD n CBN ratio effects are less than subtle and are somewhat predictable in their effects.

It gets a lot more complicated when you factor in the multitude of THC stereo-isomers.
Delta-9 gets the most press, but is not the only psycho-active isomer.
To make matters worse, the relative concentrations of different isomers in any given sample is in a state of flux.

Heat, light, and age will shift one form to another.


(Isomer:- Same molecular ratio with a different arrangement of bonds.)

So, 5 different strains don't just give us 5 different highs.
When ya chuck in other variables, like harvest timing, heat, UV, curing method, and age.
You can build a side effect "spice rack":cool:.
Different ailments require different side effects, yah?

The world is fun today.:)
