About CBD Spectrum
Genetics & strain profile
CBD Spectrum Autoflower is a feminized autoflowering strain. It comes from a CBD-dominant cultivar crossed with Ruderalis. It has 8 to 20% CBD and very low THC, 0.4 to 0.9%. The CBD range is wide, so any one plant will land somewhere within it, and the page describes it as a fast, beginner-friendly autoflower. It carries our beginner-friendly badge. The page makes no medical claims and neither do we: CBD content describes the plant, not what it will do for any person.
It has no reviews yet, so what you read here comes from the breeder’s description and not from customer grows, and we will not claim results beyond that. Autoflowers are forgiving, but forgiving is not the same as maintenance-free: water and feed with care and check the plants regularly. Our seeds are guaranteed, so if a seed does not come up, contact us.
How CBD Spectrum Autoflower grows
Because it is an autoflower, it flowers on its own schedule without a change in light hours, so you can run the same long-day lighting from start to finish. It finishes in about 8 to 10 weeks from seed. The plant reaches 60 to 120 cm, a wide range, so leave room for the taller end. It gives up to 375 to 450 g/m² indoors and 110 to 150 g per plant outdoors.
Sow directly into the final pot, because autoflowers dislike being transplanted, and keep the medium damp but not soaked at about 22 to 25 °C until the seedling breaks the surface. Keep the room steady, with consistent temperature and humidity, because stress can slow an autoflower and cut the yield. Water gently, feed lightly and harvest by the trichomes rather than by the calendar. Outdoors, sow after the last frost so the plant has the whole warm season. Yields are best cases under good conditions, not promises. Check your local rules before you plant.
Taste, aroma and effect
Herbal and earthy, with light citrus notes and often a mild sweetness. With very little THC, the effect is calm, clear and functional. With very little THC, newer consumers should start with a small amount, since effects vary from person to person. Any flowering cannabis gives off a smell, so plan for odour control indoors.
