After about 15-20 years of dabbling in cannabis. I have found that type 1 flowers with high amounts of CBG seem to look frostier than your average type 1 without CBG.
The CBG seems to add longer trichome stalks and make the buds look more covered in frost.
Can anyone explain or link me to anything explaining WHY please?
It doesn’t seem to have this effect when the type 1 has more CBD, CBN, or other minor noid.
I have noticed that in many type4 plants (cbg) that they have this icy look to them even though they don’t contain high cannabinoids like a type 1 might. The White CBG certainly has this and strains created from it can carry it down.
Matterhorn for instance is a different cbg variety which seems to have shorter stalks on the trichs and it doesn’t have the “white” look to it.
Here are a couple articles published by NIH on this subject.
‘“Type I” plants comprise of individuals that contain predominantly THCA, and contain low levels of CBDA;
“Type II” plants contain THCA and CBDA in approximately equal ratios;
“Type III” plants have high levels of CBDA, and relatively low levels of THCA;
“Type IV” plants contain CBGA, which is also the precursor compound to both CBDA [7] and THCA [8], as the predominant cannabinoid;
“Type V” plants are characterized by undetectable amounts of any of these three cannabinoids and are referred to as “cannabinoid-free”’
‘the minor phytocannabinoid are not randomly distributed between the different chemovar types. As is shown in the heatmap presented in Figure 2, phytocannabinoids from cannabitriol (CBT) and cannabinol (CBN) families are more abundant in Type I chemovars, as they are predominantly the degradation products of THC. They can also be found in type II chemovars, though their concentration would generally be lower due to limitation in the amount of available precursor. Similarly, phytocannabinoids from cannabielsoin (CBE) family are more abundant in Type III chemovars as they are the degradation products of CBD and can also be found in type II chemovars to a lesser extent. Type-IV chemovars contain unique phytocannabinoids from the cannabigerol (CBG) family and high levels of phytocannabinoids from the cannabichromene (CBC) family, as CBCA synthase is intact. These selective distributions among chemovars are the result of metabolic pathways unique to either THC or CBD, which are not found in type IV chemovars’
I know this didn’t get much replies but this may be interesting to you OP,
(not an ad but it seems like they crossed type 1 with CBG strains to induce faster flowering, maybe you found a phenotype that contained this trait naturally?)
In my experience cbg will crystallize very quickly, a little more readily than cbd of the same quality. Maybe it has to do with the concentration/potency of the material, but I have always assumed it was temperature related and that cbg just wants to be crystalline at room temp. But I don’t have any data to back it up. But here’s some flasks of 1st pass cbg distillate crashing out during processing. Cbd does this as well but cbg has a quicker rate of crystallizing.
I would guess this visual effect is related to this characteristic of cbg.
Regarding looking frostier, at least in thc strains, it often has to do with the different types of trichromes, not all of which contain cannabinoids. That’s why a lot of modern strains can look amazing but not test very high.
