Rock Bud by Soma Seeds
If you were hanging around the Amsterdam scene when Soma was pushing out his organic soil lines, you already know about Soma A+, better known as Rock Bud. Soma took Super Skunk, Big Skunk Korean, Afghani, and Afghani Hawaiian, and threw them all in the blender. What he ended up with was a near-pure Indica that lived up to its name perfectly. The buds are so dense they literally feel like gravel in your palm. It's a squat, tough-as-nails plant that shines in a sea-of-green setup and basically shrugs off spider mites.
One of the best things about running Rock Bud is the late-flower color shift. Right around the time you start your flush, the sugar leaves turn this crazy reddish hue that looks like autumn maple leaves. She's usually done in 8 to 10 weeks, pumping out tight, mold-resistant nugs that make trimming a total breeze. You won't find a bunch of airy popcorn fluff on this one. It's all structural integrity, built for growers who need maximum weight in minimal vertical space.
As for the smoke, this is classic knockout gear. The high hits the body hard and doesn't let go, making it top-tier for medicinal users dealing with pain or insomnia. You won't get much done after twisting up a joint of this. And the genetics are so solid that DNA Genetics and others used Rock Bud to build legendary crosses like RockStar and Rocklock. It’s a nostalgic, heavy-duty Indica that reminds you exactly what the early 2000s Amsterdam scene was all about.

Growing Rock Bud: what to expect
As an indica-leaning plant, expect a modest stretch after the flip (roughly 50–100%) and dense bud structure — which makes late-flower humidity discipline the main risk: keep RH in the 40s once buds fatten to stay ahead of mold. Growers familiar with Super Skunk or Big Skunk Korean will recognize much of its behavior. Whatever the listing says, the cut in YOUR tent is the ground truth: log feedings, readings, and photos, and let the trends — not the label — drive decisions.
