Harvest Timing

 

The logic behind harvesting at a specific time is easier to understand. The usual aim of timing the moment of harvest is to ensure high THC levels modified by just the proper amounts of CBC, CBD and CBN, along with their propyl homologs, to approximate the desired psychoactive effect. Since THC acids are being broken down into CBN acid at the same time they are being made from CBD acid, it is important to harvest at a time when the production of THC acids is higher than the degradation of THC acids. Every experienced cultivator inspects a number of indicating factors and knows when to harvest the desired type of floral clusters. Some like to harvest early when most of the pistils are still viable and at the height of reproductive potential. At this time the resins are very aromatic and light; the psychoactive effect is characterized as a light cerebral high (possibly low CBC and CBD, high THC, low CBN). Others harvest as late as possible, desiring a stronger, more resinous marijuana characterized by a more intense body effect and an inhibited cerebral effect (high CBC and CBN), high THC, high CBN). Harvesting and testing several floral clusters every few days over a period of several weeks gives the cultivator a set of samples at all stages of maturation and creates a basis for deciding when to harvest in future seasons.

sorry to burst your bubble train, but this is common knowledge with most growers. the longer you leave buds mature on the plant the more i suppose 'body stone' you will get rather then a THC head high.

i recall many people here talking about this method.

No bubbles burst. This was also posted in relation to the topic-Harvesting while lights on or off.

I would also like this clarified.(  inhibited cerebral effect (high CBC and CBN), high THC, high CBN).

How can a late harvest have a high/higher ? THC at this time, when he states earlier that harvest will have a lower THC content as it breaks down to CBN, the more mature a plant gets ???

Or am I just reading it wrong ???........

yeah i think you are getting mixed up when he mentions THC twice he's talking about the production & degradation/change into CBD's and the fact that it sorta eat's one part of itself to make the other.   

but from what i read from that is yeah the same thing we know, for example one way of doing that is check the 'hairs' and let them brown off and grow new again, some people do this 3 times before harvesting.

What do you make of this ?

 

Here is a very interesting excerpt that I found on grasscity.

 

"Dr. Paul G. Mahlberg who found that THC in the resin head is at it's peak when it's still clear - not opaque and certainly not amber. Dr. Mahlberg stuck a tiny syringe into the bulbous head of the trichome and extracted it's contents, then analyzed it for THC. The result: Without a doubt, THC is at it's highest before the trichome turns opaque

I don't see how that is relevant to most ppl as most ppl don't imbibe Cannabis fresh off the plant.

 

Has this research ever been repeated? Does this hold true for all strains and phenotypes of Cannabis?

THC is but one of the active ingredients within Cannabis. It is a combination of THC, CBN, CBD, CBC and the differing levels of each that have the desired effect.

For me personally, I smoke Canna to assist with a medical condition, I need a heavy body stone to have the desired effect to meet my needs. This is why I am one of the people TSJ mentioned about ".....some people do this 3 times before harvesting". I have previously gone 4 times but I did not obtain any great benefit over the 3 times and now just go 3 as a regular. I do not grow the same strain over and over and due to this I have a nice variety of smokes depending on my needs. But even in storage the levels of each component varies over time, but the variety means somewhere in my collection I have what I need.

Marijuana Botany is a notoriously out-dated and ancient text. Many advances have occurred since the release of that book. Reading that book for anything outside of entertainment is like reading ancient texts on alchemy if you desire to learn modern chemistry. As for your last post trainwreck; I think he has been speaking with jan copeland. tsk tsk.

If the information about the internal functions happening within the plant are so out of date or even wrong, then enlighten us with the updated/correct explanation.

The point of the topic is information, not hot air. Share the knowledge. "many hands make light work".

The second post was taken form a study done by a Dr. Paul G. Mahlberg, printed in an article by high times , called "Resin Factory". If I had the rest of his paper I would post it.

Do you have the date that the High Times article was published?
