I've got quite a bit to say so bear with me.
@Nosias Not the least of which is thank you for the Rep!!
The GCA produced some of the most dense and solid buds I have ever grown.
The colors and the feel of them just screams excellent dope.
At first, with only a 4 week (or so cure) I was not very happy.
The buds had an off aroma, sort of "grassy" but not like they had turned or were two moist (bad cure).
The flavor has remained fairly consistent from that point through the present: a mango/citrus"y" initial taste followed by an almost spicey/black pepper kind of palate. Strange.
I admit, I didn't initially care for the taste or the smell but;
with more cure time, the nugs/jars smell much more spicey/skunky (dank) and cutting up a nugget smells delicious and quite dank.
The taste has not improved or changed but is a smooth smoke, not harsh and I can take fairly large bong hits as compared to other strains.
I am a taste guy and like my weed to be sort of smooth-sweet if that's a description. The best weed is one that leaves me exhaling saying yum yum yum that's tasty smoke.
GCA does not do that for me but it does pack a whallop with an initial head rush/high followed by a creeping body buzz. It makes my knees feel like they are "grinning" from ear to ear (tendon to tendon??) LOL.
Here is another personal observation: Twice now I have noticed (and been accused of) being "testy" or "short fused" temperamentally over the past 3 months and that's not my norm. I am a no hassles type non confrontational, status quo not easily angered kinda dewd. I had to agree with my GF that I was indeed quick to go off and both episodes were when I had brought out the GCA to use solely for a few days. Not sure it has anything to do with the weed as I am like you, human and prone to complexities but; I am an investigator and fairly observant and inquisitive with a research oriented personality. It's hard to shake out but I am continuing to test my null hypothesis on this matter.
In summary (and this is only one chronic tokers opinion), GCA is good for getting baked (and I've read is an awesome rosin producer) but it doesn't taste as pleasant as I would like and may cause irritability and a desire to tell the world to fuck off!! Hope this helps my friend. (ps I'm still holding about 6 ounces from that one auto)
A grower friend shared his beans after a massive breeding project with the SSDD. So now have all these beans that I will probably drop into the police stations and town hall flower pots for giggles. They grow so darkly no one might notice?
