Flak Jacket Regular Seeds by Archive Seed Bank
Archive Seed Bank crossed GMO x Chem 91 x Face Off OG #4 to build Flak Jacket seeds, and this is about as heavy-hitting a lineage as you'll find at my booth. Three hard-hitting chem lines stacked into one pack, running 23% to 25% THC. This is a pack for growers who want raw gas power, not a beginner's first run.
The Cross
GMO brings that garlic and burnt rubber funk that stops people cold. Chem 91 and Face Off OG #4 stack on the OG gas backbone underneath, with a Cookies undertone poking through on the finish. Caryophyllene, limonene, and myrcene round out the terpene profile, which is exactly what you'd expect from this kind of chem-heavy stack.
What to Hunt For
These are regulars, so expect real spread across the pack. Look for phenos that lean into the GMO garlic funk versus ones that push harder toward the Face Off OG gas. The keeper here is going to be the plant with the loudest nose and the densest flower, the one that makes your whole grow room smell like it needs a filter upgrade.
Running It
Flower time runs 7 to 8 weeks, though expect dense flower to hold on closer to 9 weeks before it's fully done. Yield is high, difficulty is moderate, and this is a vigorous plant that's going to need real filtration once it starts stacking resin. Well suited to solventless work if you're running for hash or rosin.
Worth knowing: skip this pack if you don't have odor control sorted, the burnt rubber and gas funk on this one is strong and it shows up early in flower.
No restocks, so what's on the shelf right now is what's left. Sixteen years of building relationships with breeders like Archive Seed Bank comes down to moving packs like this one. If Flak Jacket is on your list, grab it now, lock the genetics in, don't wait on this one.
