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.

White cannabis strain that is covered with crystals.

This strain appeard in Holland at the beginning of the 1990’s and quickly became a hit in all the coffee shops and not long after around the globe. It is a potent cross of a Brasilian and an Indian sativa. Its name stems from its immense crystal production that makes it shine and glimmer. White Widow can be grown both indoors and outdoors finishing indoors in around 8 weeks and outdoors in late October. This is a great strain for wannabe breeders but will also suit those that enjoy an easy to grow strain with a very strong sativa effect.

None germinated. Finally had to stop dealing with customer support because they were making me jump through hoops trying to get replacements. wish I never did.

Unfortunately, none of the seeds "popped" to germinate. The 3 blueberry did, however, zero white widow. I realize this is out of your control, however, I wasn't expecting all 10 seeds to not sprout.
