THC degrading to CBD

[ReturnOfNog]

So it's well known that if you leave a plant to flower longer some of the THC degrades to CBD, and the smoke is more couchlock.

But say you harvest half the plant at 6 weeks, and the rest of the plant at 10 weeks, well the early harvested buds are the same age as the later harvested buds, they were just picked earlier.

So at the end of 10 weeks from flowering, if THC degrades to CBD, then the early picked buds would have had the same amount of THC degrade to CBD as the later harvested buds, correct?

The difference is the buds picked at 6 weeks would go through the degradation of THC to CDB while off the plant, while the ones harvested would go through the degradation of THC to CBD while on the plant, correct?

Or does THC degrade to CBD quicker while the buds are on the plant and then slow down after the buds are harvested and dried?

thc doesn't degrade to cbd, it converts to cbn.

cheers,.............................gps

There is a good paper written on flowering times and cbn conversion and THC production...

Only 1 strain out of 30 I believe increased in enough cbn to matter....all increased in THC tho...

By week 13 I don't think the electricity was worth the additonal thc tho..

There is a great graph in the paper.

Here you go ReturnOfNog -

The concentration of D9-tetrahydrocannabinol (THC) and cannabinol (CBN) in cannabis plant material (marijuana) of different varieties stored at room temperature (20-22o Celsius (C)) over a four-year period was determined. The percentage loss of THC was proportional to the storage time. On average, the concentration of THC in the plant material decreased by 16.6% ±7.4 of its original value after one year and 26.8% ±7.3, 34.5%*±7.6 and 41.4% ±6.5 after two, three and four years, respectively.

Looks like you are right, THC degrades to CBN.

THC (delta9-tetrahydrocannabinol)

THC is the main psychoactive component in marijuana buds, and mimics the action of anandamide, which is a naturally occurring cannabinoid in the brain.

Quick Summary of THC

THC seems to provide certain positive health benefits, especially when combined with other cannabinoids

THC has the strongest psychoactive effects

THC can cause feelings of creativity, curiosity, or excited well-being

High THC levels may cause people to feel anxious, disorientated, drugged or "messed up"

THC appears to...

Relieve Certain Types of Pain

Be Neuroprotective (helps stop brain from degenerating over time)

Cause Relaxation

Cause Euphoria

Contribute to Altered Space-Time Perception

How to get high levels of THC in your buds:

THC levels in buds are determined mostly by strain (genetics). Most popular strains these days are high in THC unless otherwise stated. Choose a high-THC strain to get the highest levels of THC. Learn about a few trusted strain breeders.

THC is found primarily in trichomes on marijuana buds and (for some strains) on leaves, stems, and other parts of plant

Increasing overall resin production in a high-THC strain will usually increase your overall THC levels

Harvesting when trichomes are milky white or cloudy with just a few amber trichomes starting to appear will result in highest levels of THC

This page covers how to grow dense buds, but nearly all the techniques will help ensure your buds grow to their full THC potential, too.

Having a high THC content by itself does not necessarily mean that the marijuana is great. It's important to look at the whole experience caused by the plant, which includes considering the effects of CBD and CBN.

In fact, the following negative effects of THC are often prevented when higher levels of CBD or CBN are present:

Lapses in Memory

Disorientation

Anxiety





CBN (Cannabinol)

Quick Summary of CBN

CBN is also psychoactive, though much less so than THC

The presence of CBN with THC may reduce the feelings of anxiety that some people feel with high levels of THC

CBN contributes to more of a body "couchlock" effect

CBN promotes uninterrupted sleep

Too much CBN can make people feel groggy or sleepy

How to get high levels of CBN in your buds:

Wait longer to harvest for higher levels of CBN

In fact, CBN levels in buds are influenced almost completely by the maturity of buds at harvest

For highest CBN levels, harvest when trichomes have started turning amber/yellow





CBD (Cannabidiol)

Quick Summary of CBD

CBD is not psychoactive and doesn't make you feel impaired

CBD seems to have many positive health implications

The presence of CBD can alter some of the subjective effects of THC. Higher levels of CBD reduces the psychoactive effects of THC, which can be a great way for some patients to get the medical benefits of THC without having to feel "high".

We've always known about CBD, but originally we didn't think it had much of an effect on people. Further studies have proven we were very wrong, CBD has a big effect on the subjective experience of using marijuana, as well as for your health.

CBD appears to:

Reduce pain

Prevent seizures and spasms

Relieve some types of inflammation

Reduce anxiety

Protect Your Brain (has neuroprotective effects)

CBD has also been shown to:

Have a calming effect

Act as an antipsychotic for people suffering from schizophrenia

Offer relief for some patiens suffering from Multiple Sclerosis, Fibromyalgia and Epilepsy

Possibly help stop the growth of cancer by inhibiting cancer cell growth

Prevent the memory impairment and disorientation associated with THC

How to get high levels of CBD in your buds

Like THC, CBD content in buds is primarily determined by strain (genetics)

CBD is often confused with CBN, which can be affected by harvest methods

There is not much you can do to increase levels of CBD besides choosing a high-CBD strain

CBD is often naturally found in higher amounts in low-THC varieties of cannabis such as hemp, and is also often found in higher levels in auto-flowering strains which are derived from a type of wild hemp

In recent years, some high-THC strains have been particularly bred to also include higher levels of CBD

I’m curious of the storage methods used other than the fact it was stored at room temperature. Sealed, vacuum sealed, etc. Are there other criteria that may affect the degradation (or preservation) of THC? Or is it just a rate that happens regardless…kind of like a half-life.

....interesting topic. Subd

 

[blastfrompast]

Id be curious to see the same test, vac sealed, but back filled with N. and kept in the dark in a freezer lets say...
