Bomb Seeds (you'll also see it written as bombseeds) does one thing with total focus: breeding cannabis for big THC numbers and heavy harvests. Every bomb seed we stock is feminized, four of the thirteen strains run on autopilot, and nothing makes their catalogue unless the numbers hold up.
The brand started in 2009 and now runs its head office out of London, with breeding and testing split between Spain and the Netherlands. THC Bomb came first and still anchors the whole line: a compact plant around 90cm indoors, testing at 25% THC and filling out in 8-9 weeks of flowering. More than fifteen years later the recipe hasn't changed. Take a proven classic, cross it with Bomb genetics, stabilise the result, and only release it once quality, potency, and yield all deliver.
THC Bomb is the obvious starting point, and not just for the name: 25% THC, up to 650 g/m², and an earthy, sour smell that gets properly loud in the last two weeks of flower. Atomic pushes further, testing at 26% THC (the strongest in the range) thanks to a THC Bomb x (Chemdawg x Kush) pedigree. Gorilla Bomb takes Gorilla Glue and layers sweet diesel over a chocolate edge. And Big Bomb is the yield monster, hauling up to 850 g/m² indoors. One honest catch there: Big Bomb tests around 17% THC, so it trades punch for weight.
Here's the complete list, so you can match flowering time and yield to your setup before you commit.

|---|---|---|---|---|
| THC Bomb | Photoperiod | 25% | 8-9 weeks | Up to 650 g/m² |

Most of the range sits in the easy-to-moderate bracket, and the compact heights (90-150cm) suit small tents well. Berry Bomb and Edam Bomb finish fastest at 7-8 weeks, while the autoflowering options go from seed to harvest in 8-11 weeks total. If you'd normally reach for Royal Queen Seeds' Fat Banana, Banana Bomb covers the same sweet tropical ground with THC Bomb structure underneath. Worth knowing before you plan a breeding project: Bomb Seeds makes regular seeds too, but we don't stock them, so if you need males, head to our regular cannabis seeds instead.
High THC and heavy yields. The breeder started in 2009 with THC Bomb and has kept the catalogue small on purpose: 13 strains, each crossing a proven classic with their own Bomb genetics.
Every Bomb Seeds strain we stock is feminized, including the four autoflowers. Bomb Seeds does breed regular seeds, but you will not find them at Zamnesia.
Atomic tests at 26% THC, just ahead of THC Bomb and Gorilla Bomb at 25%. If you want the opposite end, Edam Bomb sits at a mellow 15%.
The photoperiod strains flower in 7-10 weeks; Berry Bomb and Edam Bomb are quickest at 7-8. The autoflowers run 8-11 weeks from seed to harvest.
