I have it on the devices, but I can tell already it’s one I’ll be thumbing through with great regularity. I’ve found my textbook. Thank you for the links @lazyfish.

I know right... Everything is better with Bacon.

Now we just have to get Oldbear to test the THC saturation point of bacon grease and let us know the best ratio...if his arteries survive the experiments .

Cannabis-infused bacon fat.... sounds like a match made in heaven. Lol!

From Chapter 4 of the Handbook of Cannabis

Many guides in the gray literature advise that cannabis plants are at peak potency and ready for harvest only when the capitate stalked trichomes are at the milky white stage. However, a study of over 300 dry cannabis samples indicated minimal correlation between trichome color and potency, except in relation to darker brown samples, which are clearly past the peak of potency (Potter 2009, p.77).

My c-99 BB Fast is almost all cloudy with very little amber. I guess it time.

Isn't darker brown what we call amber? Unless they are talking about something even darker than that, like when everything has gone to CBN.

I believe he's speaking of amber coloration Shed. I was intrigued that they didn't find any increase in potency. What they had to have found - if they looked - was a changing terpene profile, which, IMO, has more to do with the effect you'll feel.

I found this later passage interesting. It seems that caryophyllene is found in the capitate sessile trichomes, on parts of the plant other than the blossoms, a bitter deterrent for grazers. This followed a discussion of how capitate stalked trichomes entrap insects, with an interesting point about the alarm pheromones some insects emit that keep away others of their kind.

I don't think that's the only place on the plant this terpene is found.

Restricted allocation of capitate stalked trichomes to floral tissue is widespread throughout the plant kingdom, where plants optimize investment in defense by allocating secondary metabolites to tissues in direct proportion to their value (Herms and Mattson 1992). It is notable that sessile trichomes play no part in insect entrapment, suggesting that these had a different function, likely relying more specifically on their bitter caryophyllene content to deter herbivorous attack. When separate, fresh capitate stalked and sessile trichomes have been removed from the same plant and analyzed, the capitate stalked samples exhibit a much higher proportion of volatile monoterpenes, which give the trichome contents a solvent-based adhesive quality (Potter 2009, pp. 96–97). The cannabinoids cannabigerolic acid and tetrahydrocannabinolic acid have been shown to cause apoptosis in insect cells, and it has been suggested that this is an important defensive role for cannabinoids in capitate stalked and sessile trichomes (Sirikantaramas et al. 2005). The different ratios of cannabinoids and terpenes, between floral-derived stalked trichomes and more foliar-derived sessile trichomes, emphasizes the importance of maintaining a consistent balance of leaf and flower material when the material is used to manufacture a complex botanical drug, such as Sativex®.


Every time I go to read more I get more excited.

Interesting! Whole (above-ground) plant edible oils seems to be the recommendation here. Then the roots (if they truly are higher in CBD as we hope Neil can consistently show) can be used for those applications requiring a more CBD-based medicine.

Does all this make your skin tingle with excitement too Shed. Lol! Ok, one more.

In Jamaica they employ workers in the cannabis fields to rub their hands up the branches, lifting oils and depositing them on their ever-moving appendages. It's at once painful and fascinating to watch. Lol! They do this for hours and then scrape the accumulated material from their palms with big-ass knives.

Turns out that when the tiny bulbous trichomes (which are found all over the arial part of the plant) are ruptured it signals an increase in nearby capitate stalked trichome expression - they'll grow larger in size, and may be producing a more potent (to humans) oil in those chemical factories we grow in hopes of harvesting. Jamaican cultivators already know that the abused plant rewards with more oil. We're the ones pampering our plants and missing out on the opportunity. Jamaicans do it to get supplemental product. Two oil harvests from the same plant.

Hmmmmmmm.......

The bulbous trichomes aren't believed to hold cannabinoids. When they grow CBG chemovars the other trichomes express milky in appearance (all that cannabigerol) but the bulbous ones stay clear. I'd sure like to see some lab results from selective samples. We know very little about the effects of the "minor cannabinoids."

Isn't this fun? This book is great reading.

Talking about making bubble hash:

“Although usually performed to collect capitate stalked trichome resin heads from floral tissue, it can also be used to produce sessile trichome-based hashish. This proves especially useful in the production of CBC-rich resin.”

 

[SweetSue]

Thigmomorphogenesis - mechanical perturbation whereby the stems are brushed almost flat daily for the first 2-3 weeks of growth to beef them up in anticipation of heavy yields.

They borrowed this from the culinary herb industry.

 

[SweetSue]

I may have found my answer about terpene changes between weeks 6-10. From page 31:

“Separate tests have compared the monoterpene and sesquinterpene profiles of the chemotyoes used to produce THC and CBD for Sativex. These were seen to vary little over this same period.”

Not sure what to make if it, since as a grower I know the scent they put off increases with maturity. How can that not change the terpene profiles?

 

[SweetSue]

Page 34: “The amount of energy needed to biosynthesize terpenoids molecules has been calculated to be up to three times greater than that required to synthesize an equivalent weight of sugars. (Gershenzon 1994)”

So how do I do this and where can I see the video?

Hug your plants!!!

I’ll see if I can find one for you Bobby.

I’m into chapter 6 - the pharmacologic effects of cannabinoids (6.3.2) - and I’m reading about THC being a partial agonist for CB1 and CB2 receptors. 11-hydroxy THC is a better connection than delta-9.

So I’m wondering.... if the effect we want from THC is to stimulate the receptor, and 11-hydroxy appears to do this better than delta-9, what change in the signaling occurs that makes 11-hydroxy less useful as medicine? Hmmm.....

 

[SweetSue]

I’ll see if I can find one for you Bobby.

Here ya go. They start talking about charas at around the 20:00 mark. Then they go to a field and demonstrate.

Here is my first oil extraction in the instant pot. I left the buds whole. Its about one third jfx and two thirds crescendo 11 in mct coconut oil. 110 min at high pressure in a pyrex covered with foil. Now its cooling.

I have been wondering why we dont add the lecithin during extraction rather than after.
