About this format
Cannabis seeds are sold as collectable souvenirs and for the preservation of genetics. Feminized seeds grow into female plants, autoflowers switch to bloom on their own regardless of light schedule, and regular seeds produce both sexes for breeding. Germination is illegal in many countries — know your local law before you buy.

Granddaddy Purple Autoflower: California Classic, Auto Speed
Granddaddy Purple is one of California's most recognisable indicas, and Royal Queen Seeds has brought it into an autoflowering format without losing what makes it worth growing. The purple-blushed buds are the first thing you notice, dense and visually striking before the jar is even opened. The lineage does the heavy lifting here: Purple Urkle brings the deep colour, the berry-candy sweetness, and the body-heavy indica character, while Big Bud Auto adds bulk and the ruderalis genetics that make the whole thing light-cycle independent. At 19% THC, this sits firmly in experienced-user territory, a strong indica that earns its evening-only reputation.
Sown to harvest in eight to nine weeks, this is the quickest finish here. Its counterpart, Granddaddy Purple Autoflower (Zamnesia Seeds), wants nine to ten but reaches 500 g/m2 instead of 450.
Compact, Fast, and Surprisingly Easy
The growing profile is one of the clearest arguments for this auto over its photoperiod counterpart. Seed to harvest lands at 12 weeks, which makes scheduling straightforward and multi-run seasons realistic. Indoors, plants stay between 70-120cm, compact enough to fit a standard tent without aggressive canopy management. LST works well if you want to open up the structure; topping is debated for autos and most growers skip it. Outdoors, expect plants around 140cm with a yield of around 160g per plant, manageable and tidy. Indoor growers can expect up to 450g/m². One detail worth knowing: cooler night temperatures during the later stages of growth intensify the purple pigmentation considerably. It won't change the smoke, but the visual payoff is real.
Berry on the Cure, Pine on the Exhale
Fresh from the jar, the aroma is berry and candy with a floral lift and an earthy base underneath. On the palate, the sweetness carries through but shifts toward pine and herbal notes on the finish, two distinct moments rather than a flat profile. The effect follows the indica blueprint: a relaxing body stone that settles into something calm and happy, with a sleepy, muscle-easing quality that makes it a natural end-of-day strain. This is not a daytime smoke. Keep it for the evening and give it the time it deserves.
