High CBD seeds grow plants rich in cannabidiol with low to moderate THC, for growers who want the character of the plant without a strong intoxicating effect.
High CBD cannabis seeds grow plants rich in cannabidiol with low to moderate THC. They are described by ratio: a 1:1 strain is balanced and mild, while ratios like 1:20 are strongly CBD-dominant and produce very little intoxication. Growing them is no different from any other cannabis plant, but harvest timing matters more because it shifts the cannabinoid balance.

Ratios describe how much CBD there is compared with THC. A 1:1 strain gives a balanced, mild effect. Ratios such as 1:20 lean heavily toward CBD and produce very little intoxication. The higher the CBD side, the gentler the result. Every strain page lists its ratio and cannabinoid range so you can choose deliberately.
Start with a balanced 1:1 hybrid to see how you like it, then move toward a CBD-dominant ratio for even less THC. For the easiest possible grow, our auto CBD seeds finish in eight to ten weeks. Cannabis affects everyone differently, so speak with a healthcare professional about your own circumstances.

Times shown are typical ranges from seed to harvest and vary with strain, climate and setup.
The first number is THC and the second is CBD, so 1:20 means roughly twenty times more CBD than THC. Higher CBD ratios produce progressively less intoxication. A 1:1 strain is balanced and noticeably milder than a typical high-THC variety.
CBD-dominant strains produce far less intoxication than high-THC cannabis, and strongly CBD-dominant ratios produce very little. Balanced 1:1 strains still contain meaningful THC and can be mildly intoxicating. Effects vary between individuals.
No. They grow, feed and train like any other cannabis plant and need no special equipment. The one difference is that harvest timing is more important, because letting plants run long changes the ratio of cannabinoids in the finished flower.
Yes. Both photoperiod and autoflowering CBD varieties are available, so you can match the plant to your season. In shorter-season regions an autoflowering CBD strain finishes in 8 to 10 weeks and avoids the autumn frost risk.
Most growers start with a balanced 1:1 hybrid to see how they respond, then move toward a CBD-dominant ratio such as 1:20 if they want less THC. Cannabis affects everyone differently, so speak with a healthcare professional about your own circumstances.
Cannabis plants grown at home are regulated the same way regardless of cannabinoid content, so the same four-plant household limit and provincial rules apply. Quebec and Manitoba prohibit home cultivation entirely.
