I'm finding different answers everywhere online like this Google search that totally contradicts each other?
Ive grown probably more of the original gg4 S1 that went around the commercial facilities then any other one plant. As far as that gorilla glue goes, there is a good reason imho that it gets called both.
From the grower's perspective, its a lanky plant, with a fairly thin finger to the leaves, and a pretty big node spacing on average.
But, from the smoker's perspective, that original gg4 was a pretty stoney plant. Its a smiley, uplifting to the mood plant, but it is really stoney still. A lot of dispensaries would call it an indica hybrid because it was a more accurate way of describing the effects most of the time.
The plant itself is just a lanky hybrid, and depending what spectrum of lighting, from sun, to hps, to LED, its one that tends to express with a lil bit different structure to the flower as well. I could also NEVER get color from the buds through to end cured bud. I could get some streaks on leaves and sugar trim with cold temps, but it just stayed a vibrant, almost neon lime green through growth on the flowers.
I always considered it a pretty even hybrid, with sativa leaning tenencies in growth, especially in flower, but indica leaning tendencies to the quality of the high.
It also did this really cool and unique thing, where the buds looked fluffy, but when you pick them up, they are not fluffy at all lmao.
Ive also never grown another plant that so heavily required netting or yoyos indoors. If you didnt, the plant just flopped around all over the place and all over itself, even with elevated silica to the feeds lmao.
gorilla glue was a strange plant, and honestly, along side some of the gelato and Bubba lineages, probably one of the legendary plants of note in the modern era.
I recloned a clone of a clone of that original gg4, soooooooooooo many times. I grew so much gg4 flower privately and commercially from the same original clone and the plants never changed, and thats something many commercial growers had the same experience with. A lot are still growing that original clone after having already probably produced near Tonnage of the stuff. Its willingness to grow as far sideways as up, and how much of a good mood the plant was is why i ended up starting my own long term f1 project with the plant. It's def on the list of genetics i dont ever want to lose.
As for is it indica or sativa? The answer is Yes
Fun fact/The story i was given: The original gorilla glue 4 plant was not cloned for one reason or another, i assume its weak-sauce stems. But after harvest, a single viable self pollenated seed was found after significant regret for not cloning the plant. And the day was saved, and coincidentally, is one of the living legend plants that probably wont be lost to time any time soon. We dont have many of those. It was almost lost forever after a single plant lol.
The original popularized gg4 cut, was actually a self pollenated S1 seed resulting from a stress hermed plant taken real late into flower. So far as i understand it, it's a a tiny miracle any of us have ever even smoked that flower
