Your Grandpa's Weed or is UV supplementation really needed?

Since I was interested in carnosic acid I viewed several patents for extraction procedures to see if I could find a good way of extracting THCA, since they're so similar. Well, I did find several informative patents but one which may prove particularly useful is this one. It's a method for making an oleoresin extract, which is analogous to BHO or QUISO, for instance.

But what's new is their discovery that certain percentages of alcohol and water will extract the oleoresin but not the chlorophyll and other undesirables. Then they get the extract by adding more water which then causes it to drop out. But the thing is; the best percentage of alcohol turns out to be only 40-60%, whereas everyone has been using 95%. It said (in a table) that at 40 or 50% ethanol the extract was amber but higher than that it became more and more green. Apparently 50-55% is optimal. The speed of it is also interesting, only 2 minutes stirring at room temp. Not even any heat involved.

Here's the part that explains it, so you don't have to read the whole patent. Just replace "carnosic acid" with "THC acid".

It has been the surprising result of this invention that carnosic acid is substantially soluble in 40%-60% (and higher) solutions of ethyl alcohol in water and in 60%-80% solutions of methyl alcohol in water but is substantially insoluble in solutions comprising less than 40% of the alcohol. This result is unexpected. These alcohol solutions in water are not sufficiently high in the alcohol content to dissolve green coloring matter that may be present in the original material, but they form very powerful solvents for carnosic acid. Indeed the solvating capacity of the specified concentrations is such that the carnosic acid in the starting material is more than 80% dissolved in 30-60 seconds of mixing at room temperature.

Extraction solutions containing in excess of 60% ethyl alcohol or 80% methyl alcohol result in the undesirable extraction of green coloring matter together with flavor and aroma compounds and other diluent materials. Extraction solutions containing less than 40% ethyl alcohol or 60% methyl alcohol are not capable of efficient carnosic acid extraction and remove only 60% or less of the original carnosic acid. These low alcohol content extraction solutions allow an oxidative deterioration of the carnosic acid. Within the concentration range of 40%-60% ethyl alcohol and 60%-80% methyl alcohol, over 80% of the carnosic acid is extracted within 60 seconds yet no green coloration and very little flavor and aroma goes into solution.

A further novel aspect of the invention is the effectiveness of the alcohol dilution in water to precipitate the oleoresin containing the carnosic acid. To recover the precipitate quantitatively dilution of the solvent to less than 20% in the case of ethanol or less than 40% in the case of methanol is preferred.

The precipitated antioxidant oleoresins produced by the invention are recovered as light brown pastes which may be dried or incorporated directly into oils, fats, foods and other end-products. When derived from, for example, rosemary or sage leaves containing approximately 3% carnosic acid, the resulting oleoresins will contain typically 30% - 40% carnosic acid on a dry matter basis. When derived from, for example, a green colored supercritical antioxidant oleoresin produced from rosemary leaves and containing approximately 25% carnosic acid, the oleoresins resulting from the process of the invention will contain typically 50%-80% carnosic acid on a dry matter basis.

A further novel aspect of the subject invention is that other natural phenolic diterpene antioxidant compounds, such as for example, methyl carnosate and carnosol, which may be present in the starting material are simultaneously increased in concentration in the extracted oleoresin produced by the method of the invention.

The present invention is clearly effective in the selective extraction and concentration of carnosic acid from herbal materials and their extracts, and allows the production of oleoresins with the highest content of natural carnosic acid known to date.

In my outdoor growing experience a few seeds always seemed to kick it up a notch. Havent gone through the whole thread but interested in what strains you are growing. Always interested what old school strains are kicking about. My personal preff is Mexican sativa's, unfortunately dont have an outdoor growing area availible as some of those take forever to finish and are far better suited to outdoor growing.

What does anyone recommend as UV supplementation to 50W of COB LED? Should be able to scale up from a recommendation on 50W.

FWIW, COBs are putting on the frost without the UV, so I'm over here dying to know what is possible with...

Are there readily available 5-10W options, off the shelf, sure I could google but I want to know what the guys putting out the frost are using.

I tell ya what...i used to run htg digital plus bulbs before i got into Gavitas and they were in my opinion...way better than the major brands. Ran the hell.outta them for years. Htg hoods suck but ballasts and bulbs are pretty solid. I like thier phat sack 2 and 3 gallon cloth pots too. Couple few items at htg that i like and always buy. Some of the stuff is garbage but alot of it is decent. Good vid.

I just love how much you don't get it, how stuck in your mind you seem to be, tis truly entertaining and sad but I still love ya. To think that hundreds of folks just blindly follow me is so laughable. Like I meet em at the door and hand em the Kool Aid 8)

You should just wait till I get the light and post the grow and see if I'm so wrong ???

Pretty soon every one will have ya on ignore and you'll just be typin to yourself ?

There are actually folks out there that want the better weed, for some reason you don't seem to understand that ? You say you're happy with your weed, why not be happy for others that want something more from theirs ?

You come across like an aged religious fanatic yelling death to all infidels that don't grow like me, no 72 virgins for you if you don't use HPS and your smash your flouros thread kinda proves it

Just an FYI, though I truly doubt you'd seriously take the time, but I spent many hours researching this light, you see it is designed to penetrate 3 feet of water to grow coral in aquariums (if you read the whole page I posted the link to you would know this) and recommended to be 2 feet above the tank (as shown in the pics) so that's 3 watt leds with 5 feet of penetration and as stated on the "con" page they already exist and are in use on tanks all over with reviews of how well they grow coral. Tis a ironic correlation that I use T5 bulbs designed for the same thing 8)

And as I shared with you in our recent pm, if ya want true innovation ya needs to look outside the "grow" industry 8)

At the very least I thank ya for bumpin my thread

No, you're just close minded.

Cannabis the industry is crammed to the lid with BULLSHIT, designed to separate the uneducated from their money.

@RM3 hands out candy at the door, all right; joints of his own weed for people to smoke and JUDGE FOR THEMSELVES.

He certainly doesn't claim to be anything special, other than an experienced grower.

If you're so smart, where's your degree in agronomy?

I was lead to believe that the best light to grow anything under is SUNLIGHT does that mean to get the best results under lights a True full spectrum of all the colours of a rainbow would be the ultimate indoor grow light or is that just a pipe dream?:peace:???????:leaf:
