Text:  Hi, they all germinated well, and are growing extremely well. These ladies grow pretty quick, the leaves are large and resemble indica, and the internodes are close, meaning there should be plenty of bud sites and i expect a good return for my effort.

16.9% CBG with 0.25% THC from this new type of feminised cannabis strain.

Seedsman CBG #1 is a photo-period strain which has been specially bred to produce very high levels of CBG (Cannabigerol), a cannabinoid which is usually present in low concentrations in typical cannabis samples.

CBG (cannabigerol) is the non-acid form of cannabigerolic acid (CBGA) which itself is the pre-cursor to the three main cannabinoid lines tetrahydrocannabinolic acid (THCA), cannabidiolic acid (CBDA), and cannabichromenic acid (CBCA). Through the action of UV light or heat enzymes in the cannabis plant break down CBGA and in the majority of strains it is converted into either THCA and CBDA. It logically follows that the higher the CBG the lower the THC and CBD levels and vice versa.

CBG is very interesting as it is thought to offer great medical potential. It lowers intra-ocular pressure thereby helping to treat cases of glaucoma. Early research reveals promise as an anti-bacterial, it inhibits colo-rectal cancer cells in mice, has been shown to protect neurons in mice with Huntingdon's Disease, it has also been shown to increase appetite in rats and it reduces inflammation in cases of Crohn's Disease.

Seedsman CBG#1 grows in all environments, indoors, outdoors and in a greenhouse. Its indoor flowering time is between 10 - 12 weeks with yields expected to be between 400 - 500gr/m2. Outdoors, northern hemisphere harvests will be ready towards the end of September - early October with each plant capable of producing up to 350 gr. Colourful displays of purple will affect some plants towards the end of flowering especially in the presence of cool night-time temperatures. Flavours are tangy, from the terpene limonene, with berry notes.

N.B. It is very important to germinate CBG #1 seeds at a constant temperature of 80° Fahrenheit (26-27° Celsius) for optimum viability. Avoid temperature swings and fluctuations.

CBG levels are 16.9% while THC is very low at 0.25%.

seedsman sent me 3 cbg-1 seeds that were not viable. they then sent me another 3 cbg-1 seeds that also were non viable as replacement. i sugested that they should try to germinate seeds from the same batch and i do not believe that they will. will never buy anything from their company again. i asked them to remove me from the e mail list and they said they would. they just e mailed me asking me to review the seeds they sent me. not too bright!

Same scenario as before !
Reply from:  Seedsman (28.10.2026):  Thanks for your review. We do test seeds from all the batches of seeds that we sell - and only release for sale seeds that test over 95% germination - we are therefore very confident with the quality of the seeds that we sell. We also hold our suppliers to the same high standards. This said these are live products and competencies & environments vary so we try to help customers if they have issues. Please reach out to our customer service team to see what they can do to help, and check on our blog for our recommended germination techniques. Best Seedsman

Not sure what to expect,. Grew fantastic, outdoor in FFOF. Novice grower, yeild about 5oz dry. Big colas. I don't like the paranoia THC gives me and this is just feel good. Will grow again.
