100% success rate with these seeds, and a great strain! I tried some seeds from another distributor, and they were all duds. Had a few of these left over, from a few years ago and they grew long tap roots in one day! Very happy with the quality of seeds at the seed pharm.

Ace Killer OG is built almost entirely from the OG and Kush families. The strain label lists the lineage as White Fire OG, King's Kush and Kosher Kush, and it grows like it: indica-dominant, sturdy, and heavy with resin by the end of flower. THC is listed at 25%.
It is sold as feminized seed and grows as a photoperiod plant, holding in veg until you switch the light to 12/12.
What the jar smells like
The first thing out of the jar is sour diesel, the OG signature. Break a bud open and the smell shifts to pine, cut wood and wet soil, which is the Kush side coming through. It is a loud plant in late flower, so plan on a carbon filter if you grow anywhere shared.

How to grow Ace Killer OG
The label lists medium height, 100-150 cm, with flowering at 8-10 weeks. OG lines tend to stretch a little more than pure Kush after the flip, so leave some headroom and set your screen or ties before the stretch starts.
Top once in veg and train the side branches out to an even height. Feed moderately; OG-heavy plants often react to too much nitrogen late in bloom with dark, clawing leaves. Cut back nutrients in the final weeks and let the plant fade.
The buds form dense and sticky, so airflow matters more than anything in the last stretch. Thin the lower growth before flowering and keep a fan moving air across the canopy. A garden plant can return about 400 g, and an 8-10 week bloom ripens around early to mid October in the south of Canada.
