By section 6 of the Misuse of Drugs Act 1971 it is an offence to cultivate any plant of the genus cannabis in the United Kingdom without a license from the Secretary of State. Anyone committing an offence contrary to this section may be imprisoned or fined, or both. Please note therefore that germination of seeds bought from the Seedsman website without an appropriate license is illegal in the United Kingdom.

The world famous Sour Diesel is now available in feminised seed from Royal Queen Seeds.
Royal Queen Seeds are proud to add this fine cannabis strain to their selection. This might be one of the most famous strains of cannabis on the planet; and maybe one of the strongest. Like many of the best cannabis strains coming out these days, Sour Diesel comes straight from California. It is one of the favourite strains amongst many. These powerful American genetics will grow well indoors around the world; outdoors, on the other hand, they need a warm climate, similar to California or Spain. This is a mostly Sativa strain which shows in both its growth structure and the strong effect. The plant develops its resinous buds and powerful aroma over a 10-week flowering period. This is after a recommended 3-to-4 week vegetative period. These plants will grow to a height of around 100-160 cm. indoors, with some stretching during early flowering. Sour Diesel is a very pungent, aromatic strain. Heavy chemical, herbal and sour flavours come from its glistening buds. When grown well, it will give yields of 450-600 grams per square metre. This is both a yield in quantity and quality, producing high-quality, resinous, aromatic buds. Full Diesel power!

I ordered and paid for 3 packs and was supposed to receive a 4th pack free. I only received 1/2 my order or two packs. I wrote back and still do not have a resolution. Will your company be honorable and correct your error? I remain optimistic and await your response. I grew it for two years now
