THC Bomb by Bomb Seeds

Back in the late 2000s, European seed banks were locked in a massive arms race to see who could push THC percentages the highest, and Bomb Seeds dropped THC Bomb right in the middle of it. They’ve always kept the exact genetics locked in the vault, but it’s universally recognized as a perfectly balanced hybrid designed to do three things: yield massive weight, finish fast, and blow your head off with potency. It completely lived up to the hype and became the backbone for almost everything else in their catalog.
This is the definition of a workhorse strain. It stays squat and incredibly compact—usually maxing out around 90 cm—which makes it a dream for indoor growers fighting for vertical space. You can push it hard, and after just 7 to 9 weeks of flower, it produces yields that are honestly stupid. We're talking rock-hard, absolute boulders of bud that are so dense you might actually snap a pair of trimmers trying to get through a harvest. It's vigorous, handles abuse well, and just plain performs.
When it comes to the smoke, the name is no joke. Testing consistently between 20-25% THC, it delivers a massive two-stage high. You get an immediate, racy head rush that eventually settles down into a crushing, heavy body stone. The flavor isn't the most complex thing in the world—mostly earth, pine, and a little citrus-fuel—but you aren't growing this for a nuanced tasting menu. You’re growing it for maximum firepower and a jar full of commercial-grade weight.

Growing THC Bomb: what to expect
As a hybrid, expect a moderate stretch after the flip (around 100%) — but watch the plant, not the label: phenotypes within THC Bomb can lean either direction. 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.
