Well, O.C. was the first strain I ever did, which was inside, my very first grow, so it is a somewhat easy plant to grow, does well as main cola, but better I think topped, because the buds are smaller and the quality comes out better. To describe this plant its definitely orange, looks, smells, etc. The Blueberry adds sweetness, and I think it adds length to the buds. It does have a very unique smell, dominated by the sweet orange smell. very nice. It smokes just how it smells. Its not overpowering, mild actually but a very very nice high and its not weak at all, just not mind blowing. This weed done right, grown organically indoors with co2 is a jaw dropper, nothing but amazing comments on this one.
So, ten years later I got some bagseed of the Cali-O. I think the plant got stressed and threw off some seeds, not by me, mind you. anyway, This bud is definitely a straightforward orange plant, like the O.C. but without the sweetness. Its hardy, tasty, and Orange all the way. A very easy plant to grow. The taste, like I said is orange all the way, the high is a feel good every time type of toke. This bud put me in a good head space 100% of the time. Its clear, wholesome, Its just good like that. The more you smoke this bud will take you to the next level, mentally, spiritually, its a solid weed. It can be psychedelic in its own right. The real treat to this strain, is making kif. The taste is so orangey, but crisp, nothing extra. Done organically, this one cant be beat, its old skool goodness. As far as I know its a triple skunk. Skunk#1x Skunk #1 x Skunk #1. So, the kif done right, looks like a pile of coke, its so pure, but wwith an orange tinge, and the experience of this is amazing. The kif will fill your face and head with oranges. you get the point, now, right?
Done outside the Cali-O is easy to grow, 1 lb is not hard and the quality still comes through.
As far as the comparison, I prefer the Cali-0, I smoked the shit out of it, and anytime I had any type of ailment this strain brought me to a goood happy place of feeling good, its good medicine like that. The only way I prefer the O.C. is that one of the seeds I popped gave me a tangerine pheno, that honestly, was just like a succulent tangerine, but hey that was before I knew how to clone and keep a mom. haha. Peace out peoples hope this helps.
