CBD Cannabis Seeds: High CBD and Low THC Genetics

Quick myth to kill first: there is no CBD in the seed. You are buying genetics, and the CBD only turns up in the flowers weeks later, once you have grown the plant out. Cannabidiol and tetrahydrocannabinol are the two cannabinoids breeders steer with, and every ratio on this shelf belongs to a named strain, never to the category as a whole. The packs here come from across our cannabis seeds shelves, with Royal Queen Seeds, Medical Seeds, Delicious Seeds, Paradise Seeds, Kannabia, Dutch Passion, Garden of Green, Sensi Seeds, Fast Buds and our own Zamnesia Seeds all represented. And yes, one seed bank is literally called CBD Seeds: this page is the CBD topic across all breeders, while that bank sits on its own separate shelf.

CBD-dominant, balanced 1:1, or leaning somewhere in between

First fork in the road, and it is a ratio question. CBD-dominant packs put nearly all their cannabinoid weight on one side. Green Cure CBD F1 Autoflower from Zamnesia Seeds is listed at 18% CBD, and CBD ACDC from Blimburn Seeds sits at around 18% CBD with low THC. CBD Fix Autoflower, CBD Auto 20:1 and Dutch Passion's CBD Charlotte's Angel belong in the same CBD-forward camp, so read each pack for the figures it actually documents.

Balanced is the other end of the shelf: Chronical CBD 1:1 F1 Autoflower from Zamnesia Seeds carries an even 1:1 CBD to THC ratio and stays under 1% THC. Ratios that only lean, 2:1 for instance, live between those two poles, so check the individual pack rather than assuming a house average. Worth a scan too: CBDV Auto at 0.2% THC, Auto Cannabis Light and the hemp variety Kompolti. CBG and minor cannabinoids turn up on a handful of descriptions as well, listed next to the CBD rather than in place of it, so if cannabigerol is what you are hunting, look for the packs that name it.

Terpenes and what lands on the exhale

Terpenes are the aroma side of a CBD grow, and our pack copy puts them in plain flavour terms instead of lab lists. Chronical CBD 1:1 F1 Autoflower is candy-sweet with herbal notes and a squeeze of lime on the exhale. Green Cure CBD F1 Autoflower goes the other way, peppery with sweet cookie and pine. Neither profile tells you anything about the ratio, which is exactly why we keep the two decisions separate.

Nine weeks in a cupboard, or a photoperiod with room to stretch

Seed-to-harvest and flowering time in weeks

Autoflowering CBD seeds run to their own clock, counted from sprouting rather than from a light flip. Chronical CBD 1:1 F1 Autoflower goes from seed to harvest in 9 to 10 weeks, stays 60 to 80cm and can give about 450g/m² indoors or 150g per plant outside, which suits a cupboard or a balcony pot. Green Cure CBD F1 Autoflower needs 11 weeks, reaches 70 to 100cm and is listed at 450 to 500g/m² indoors. On the feminised side, CBD ACDC flowers in about 8 to 10 weeks. If you landed here after a fast finisher, the two Zamnesia Seeds autos and CBD Fix Autoflower are the short-timeline options.

Feminised photoperiods trade speed for bulk. CBD Fix flowers over a longer stretch, comes in later in the season outdoors and can stack real weight, but it stretches tall, far more than a small tent will ever swallow, so keep it for a spare room or the garden and give it height to work with from day one.

Indoors, greenhouse, or tucked down the allotment

Most of this shelf copes with all three. CBD ACDC is happy indoors, in a greenhouse or outside once the nights warm up. Green Cure was bred to slot into small grow spaces, greenhouses and guerrilla spots, and its F1 genetics come up uniform, which makes an even canopy much easier under one light. Compared with a THC-forward auto from the wider autoflowering seeds shelf, these want the same feed, the same light hours and the same care; the difference shows up in the jar, not the tent. First CBD-rich grow? We would start with Green Cure CBD F1 Autoflower or Chronical CBD 1:1 F1 Autoflower and save the photoperiod CBD Fix for a run where you have the headroom. UK orders leave fast and in plain packaging.
