About A-10
A-10 leans heavily on its earthy backbone, with a fruit-sweet top note that keeps the smoke from turning harsh. Some growers find the earthy side heavy on first contact, but the sweet aftertaste is what brings people back to it. It smokes cleanly and is the kind of jar that stays in rotation rather than getting saved for occasions.
A-10 is 100% Indica, running 21% THC with CBD under 2%. With almost no CBD to soften it, the psychoactive side comes through plainly, but 21% is moderate enough that the strain suits newcomers as well as experienced smokers. The high runs about two hours before it tails off, relaxing and euphoric rather than overwhelming. Many growers report using it to wind down in the evening or to settle before sleep.
Growing A-10 Autoflower Seeds
A-10 Autoflower carries ruderalis genetics, so it moves into bloom on its own schedule regardless of what your timer says. There is no flip to 12/12 and no risk of a light leak dragging a plant back into veg. Keep the lights at 18 to 20 hours from sprout to chop and the plant handles the rest.
It behaves like the Indica it is: compact, bushy and easy to please, which makes it well suited to indoor tents. The short life cycle means everything hinges on an uninterrupted start, so plant directly into the final pot, go light on nutrients for the first two weeks, and leave the scissors alone. Autos do not have the recovery window a photoperiod plant does.
The short, fixed cycle also opens up options outdoors. In a Canadian summer you can sow, harvest and sow again inside the same season, or tuck plants onto a balcony where the ambient light schedule would never let a photoperiod strain finish. Greenhouse and garden runs work just as well as indoor ones.
What to Expect
- Flowering: 50 to 60 days, which is on the longer side for an auto
- Height: 80 to 100 cm, no height management needed
- Indoor yield: 400 to 450 g/m²
- Outdoor yield: up to 450 g per plant
- Difficulty: easy, a reasonable choice for a first grow
Those yields are strong for a plant that finishes this fast and stays this short, which is the main argument for running the auto version of A-10 over anything else.

I’m fairly new to growing, and A-10 Autoflower was very beginner-friendly. Plants stayed compact and produced dense, flavorful buds. The high is smooth and comforting. The Seed Pharm delivered great genetics once again.
