Best UK CBD Seeds

Best CBD Seeds UK

As CBD products have grown in popularity, so have CBD seeds. So much so that numerous different CBD-rich cannabis strains are now available. We’ve written this guide to help you go straight to the seeds that are worth your time and prevent you from wasting money on inferior genetics.

Since 2016 I’ve worked for and alongside a number of UK seed banks, so I can provide a valuable insight into which seeds to choose. Here you’ll find a broad selection of the best UK CBD seeds from those with a 1:1 CBD to THC ratio to some that exceed 20:1.

Most of our choices here come from seed banks I’ve used personally and have featured on our best UK seeds banks compilation. They each offer a broad selection of varied genetics, stock the freshest seeds and have responsive customer service teams.

If you are interested in buying seeds that are rich in THC check out our piece on the best cannabis seeds available in the UK.

Buying CBD Seeds: The Law

The law surrounding cannabis and CBD seeds in the UK is very clear: It is legal to buy and sell them, but they are illegal to germinate. Germination is the process of introducing a seed to warmth, light and moisture to begin the growing process.

Seeds may be purchased as memorabilia, souvenirs, bird food or even fish bait. However, if you make a purchase and indicate that you intend to germinate them, then the seller is obligated to report it to the police. Equally, a seller must not indicate that seeds are being sold for the purpose of germination.

If you do intend to purchase seeds for germination, you must be aware that you may be caught and risk fines or time in prison. As you’re buying them for storage and preservation purposes, this won’t be an issue to you.

Disclaimer – To help you choose which genetic lines to preserve, our descriptions of seeds include details about necessary growing conditions and the plants they produce. This is included to inform your decision and refers only to seeds being grown in countries where germination is legal; it is not a suggestion of how they should be used.

What Should I Consider When Purchasing?

CBD Hemp Plant

Regs

Regular seeds have a 50/50 chance of growing into male or female plants. Some become flower-bearing female plants, and some become pollen-producing males. They’re useful for breeders because they need both male and female plants to produce the next generation of seeds.

Fems

Feminised seeds are those that breeders have engineered to produce female plants 100% of the time. This means every plant is likely to grow crops of resinous flowers and growers won’t need to weed out the males.

Photoperiod

Most CBD rich cannabis plants start to flower when the amount of direct light on them drops from around 18 hours a day to about 15 hours. They can be grown inside or outside, but they either need the correct light set up or the right time of year to produce a crop. Photoperiod seeds often produce larger plants and can reach higher THC levels.

Autos

Autoflowering seeds produce flowers after a fixed period of growth, usually 3 to 4 weeks after germination. These seeds are commonly chosen by beginners or those who don’t have enough space for the lighting necessary for indoor photoperiod grows.

CBD:THC Ratios

The CBD:THC ratio of a seed relates to the cannabinoid content in the buds on any female plants it produces. Whether you choose 1:1 with equal amounts CBD and THC, or something with more CBD and less THC, like 20:1, depends on what characteristics you’re looking for.

High CBD strains are often marketed as having medicinal benefits. Those that are also high in THC still provide a high sensation, whereas those with less than 1% THC are often referred to as purely medicinal strains because they’re less likely to be intoxicating.

Breeders Packaging

When you’ve chosen your seeds and go to place your order, it’s a good idea to request that everything comes in its original breeder’s packaging. Then you can be sure you’ve received exactly what you’ve paid for, not all retailers will do this. If they say no, then do not purchase as you cannot be sure you are buying genuine CBD seeds.
